4 asic H with LD eatures and Specifications Linear Displacement ransducer Series H-LD Solid state electronics Series H lectrohydraulic ctuators Compact design for easy installation Infinite esolution Maximum Stability No moving parts Sealed stainless steel probe withstands 000 psi Magnet Magnetostriction In a LD position sensor, a pulse is induced in a speciallydesigned magnetostrictive waveguide by the momentary interaction of two magnetic fields. One field comes from a movable magnet which passes along the outside of the sensor tube, the other field comes from a current pulse or interrogation pulse launched along the waveguide. he interaction between the two magnetic fields produces a strain pulse, which travels at sonic speed along the waveguide until the pulse is detected at the head of the sensor. he position of the magnet is determined with high precision by measuring the elapsed time between the launching of the electronic interrogation pulse and the arrival of the strain pulse. s a result, accurate non-contact position sensing is achieved with absolutely no wear to the sensing components. PULSS LUNCHD PULSS CIVD PULS IN V DC OUPU 0 td DC VOL n average of 00 ultrasonic strain pulses are launched for every reading. ith so many readings taken for each position, vibration and shock have negligible effect on the readings. he transducer assembly is shielded to eliminate interference caused by electromagnetic fields in the radio frequency range. In addition, static magnetic fields of several hundred gauss must get as close as /6" from the protective tube before any interference in transducer operation occurs.

Innovative, resistive element is made of conductive plastic. pin rad Harrison electrical connector available at any cap position not occupied by a port or mount. How It orks he Parker L is a uniquely designed position sensor that uses a resistive element and wiper assembly to provide an analog output signal of a cylinder s position. he L is a dual element type linear potentiometer with two independent elements mounted on either side of a anodized aluminum extrusion. he L operates as a voltage divider. his is done by shorting through the extrusion with the wiper assembly. he position of the wiper changes the resistive load proportional to its position along the cylinder stroke. he L is energized by applying a voltage across the unit, typically 0 VDC. s the resistive load changes with the cylinder stroke, the output voltage changes proportionally. he output voltage at the end point of the cylinder stroke is dictated by the input voltage applied across the device. he probe is mounted into the cylinder cap and inserted into the gun drilled piston rod. he compactness of the design only adds to the envelope dimensions of cylinders with -/" rods and smaller. nvelope dimensions of cylinders with larger rods are unaffected.

Other sizes can be supplied as specials on request. or heavy-duty or high-cycling applications, the use of a larger rod diameter is recommended. efer to Section C, page 96 for proper sizing of piston rods. Stroke Length If an integrally mounted position transducer is specified, the maximum stroke length will normally be limited by the type of transducer. Stop ube n internal stop tube (piston spacer) is recommended in cases where the combination of stroke length and mounting style option could result in excessive bearing loads on the piston or rod gland. Please refer to Section C of this catalog. stop tube may also be used to eliminate the need for an extended rod end with the LD Model. Mounting Styles Mounting styles available as standard on H integral manifold actuators are shown in this catalog. If other mountings are required, please consult factory. Cushioning On cylinders fitted with integral feedback, cushioning is available as a standard option at both ends. Double rod (equal area) cylinders can have the normal cushion option at both ends. Pressure atings Series H integral manifold actuators have a nominal working pressure of 000 psi. ecommended maximum working pressures for H integral manifold actuators with eedback option (LD or L) are given below. hese pressure ratings are given as a guide for typical applications. or applications involving high cycle rates, high frequencies or shock loads, please consult factory.

Utilizing the emposonics LH feedback device, there are three distinct outputs available to suit most applications. Velocity is limited primarily by the limits of mechanical components outside of the actuator, although position update Magnetostriction In a LD position sensor, a pulse is induced in a speciallydesigned magnetostrictive waveguide by the momentary interaction of two magnetic fields. One field comes from a movable magnet which passes along the outside of the sensor tube, the other field comes from a current pulse or interrogation pulse launched along the waveguide. he interaction between the two magnetic fields produces a strain pulse, which travels at sonic speed along the waveguide until the pulse is detected at the head of the sensor. he position of the magnet is determined with high precision by measuring the elapsed time between the launching of the electronic interrogation pulse and the arrival of the strain pulse. s a result, accurate non-contact position sensing is achieved with absolutely no wear to the sensing components.

In addition, static magnetic fields of several hundred gauss must get as close as /6" from the protective tube before any interference in transducer operation occurs. eatures High immunity to shock and vibration eplaceable sensing element Single voltage input + to 6.Vdc 000 psi operating pressure Multiple outputs from on-board electronics asy installation and maintenance Standard strokes up to 00" (analog), 0" (digital) Includes ' extension cable with connector standard If cylinder includes false stage enclosure, LD will be supplied with O Integral Pigtail Cable (' length). efer to pages 9 and 9 for L and dimensions. eedback ccuracy he accuracy of a given feedback device is a composite of a number of factors, the most important of which are: esolution he smallest movement of the device that will produce a measurable output. Non-Linearity he deviation of the signal from a straight line output. epeatability he maximum deviation of output signal for repeated positioning to a fixed point. Hysteresis he deviation of the signal when approaching a fixed point from opposite directions. emperature Coefficient he shift in output due to temperature change. his is a combination of the effect of temperature on the cylinder, the transducer and the electronics. hese factors which are normally additive refer to the feedback device itself. he performance achieved by a given system depends on the various factors such as system stiffness, valve performance, friction, temperature variation, and backlash in mechanical linkages to the cylinder. In the case of front flange mounted cylinders, the stretch of the cylinder due to hydraulic pressure changes may affect position repeatability and system performance. or additional information call your local Parker Cylinder Distributor. 0

54 Parker S-000 seal designed to eliminate cylinder rod seal leakage. Parker Series H Heavy Duty and Series L Medium Duty Hydraulic Cylinders with the S-000 seal offers positive protection against cylinder rod leakage under the most demanding applications. he S-000 seal is the product of countless hours of research, development and extensive field testing and is only available on Parker Cylinders. ased on the popular Parker Serrated Lipseal rod design, the S-000 incorporates the pressurecompensated, uni-directional characteristics of a U-cup with the multiple edge sealing effectiveness of compression-type stacked-packings. he goal for the Parker team was to design a rod seal suitable for all types of applications, regardless of pressure profile. It had to be composed of a ewel gland with wiperseal and S-000 cylinder rod seal. material that would not react chemically with hydraulic fluids. nd it had to produce better and more reliable dry rod performance than the standard serrated lip-seal design in a broad range of applications. he result is the S-000 seal, designed especially to eliminate rod seal leakage in the most demanding applications. It features a special polyurethane material that will not react chemically with petroleum-based hydraulic fluid, is extremely resistant to abrasion and extrusion, and provides exceptional service life. It has more sealing edges than other seals on the market, which Series H lectrohydraulic ctuators in turn produces dry rod performance. he seal geometry was refined for maximum stability in the groove and has excellent performance characteristics throughout a broad range of pressures and piston rod velocities. he Parker design team was successful! S-000 rod seal has not failed in any of the test applications in the lab or on the job, no matter how tough or demanding. or more information on the S-000 call or write your local Parker distributor or Parker Hannifin Corporation, Cylinder Division, 00 S. olf oad, Des Plaines, IL 6006, orldclass Quality Products and Service or additional information call your local Parker Cylinder Distributor.
