The primary concern of low energy switching is contact contamination. Since low energy loads do not arc or burn the contacts clean, contaminants may cause erratic switch behavior. Rockwell Automation s low energy limit switches are designed with welded gold and silver alloy contacts to provide a protective barrier against surface oxides. A stationary waffle shape contact optimizes contact pressure to stabilize the contact resistance in the region of the micro load. A prism shaped crossbar contact provides high pressure to penetrate foreign particles which could prevent contact closure. These low energy limit switches are suitable for machine connectivity and low voltage facilities. They have a low input voltage of 5 V C with contact ratings of 0.05V A min. and 0.0V A max. per pole. Bulletin 0T low energy limit switches are ideal for applications in which heavy duty pilot ratings, a high degree of versatility and a rugged NEMA Type, and P rating are required. Similar to our full line of standard 0T plug--in style limit switches, our low energy limit switches exist in lever type spring return and push type spring return. Operating heads can be mounted in four positions, 90 apart. In today s age of low energy controls, electromechanical switches are more frequently interfacing directly with low energy circuits. Switching low energy loads presents a unique challenge. Rockwell Automation is perfectly situated to assist you with all your low energy switching needs.

12 0T Modifications and Accessories Plug-in Style Oiltight Switches Manifold Mount Indicating Light Manifold Mount All two-circuit plug-in limit switches can be supplied with a special terminal base which permits mounting the switch manifold style on a machine base, panel or raceway. As shown above, this base is supplied with a wiring hole and gasket on the back. To order a manifold mount switch, add the letter U to the listed cat. no.. Example: 0T--AP becomes 0T--APU. Indicating Light Bulletin 0T two-circuit plug-in limit switches (except for the cat whisker, wobble stick, and manifold mount devices) can be supplied with an indicating light. To order add the letter N for 0V AC, 50/0 Hz or N5 for 0V AC 50/0 Hz. Example: 0T--AP becomes 0T--APN. The indicating light is internally connected to two isolated terminals in the base assembly allowing the user to wire the light to either the N.O. or the N.C. contact. Switches with an indicating light have a contact rating of NEMA A00. Where an indicator light and a pre-wired 5-pin mini connector are used, the light is pre-wired to the N.C. contact with J wiring and to the N.O. contact with J9 wiring. Indicating lights are not available on -circuit 0T switches. Fluorinated Elastomer Seals To order limit switches with all fluorinated elastomer seals, add the letter V to the end of the listed cat. no. Not available on manifold mount, low operating torque, low temperature or limit switches with an indicating light. To order lever type limit switches with the fluorinated elastomer shaft seal only, add V to the end of the listed cat. no. Base Assembly The limit switch base, including the terminal block, is available as a separate unit per the following table. --Circuit Base... 0T -X7 --Circuit Base with Indicating Light... 0T -X7 N --Circuit Manifold Mount Base... 0T -X7U --Circuit Base... 0T -X Low Temperature Operation Plug-in limit switches are designed to operate in an ambient temperature range of C (0 +0 F), C (0 +0 F) for wobble stick and cat whisker. Special limit switches modified for low temperature operation at C ( F) are available. Temperature ranges below 0 C (+ F) are based on absence of freezing moisture or water. To order, add the letter E to cat. no. Not available on wobble stick, cat whisker or pre-wired cable switches; standard on low torque and maintained devices. Pre-Wired Cable To order factory installed pre-wired type STOOW-A cable for -circuit (5-conductor) and -circuit (9-conductor) switches, add the suffix Y plus the number of feet required. Example: To order an 0T-AP with. m (5 ft) of cable the cat. no. would become 0T--APY5. The standard cable length is. m (5 ft). Extended cable lengths are available in multiples of. m ( ft) only. Mini-Type Receptacles To order a bulletin 0T pre-wired limit switch with a five-pin ( circuit) or nine pin ( circuit) mini connector, add the suffix J or J9 depending on desired wiring (J9 wiring not available for -circuit models). 5-Pin Mini-Type Receptacle Same Polarity 5 5 Same Polarity J Wiring J9 Wiring An appropriate female connector with cable (9N--F5AFC--F) is available on page -- in Connection Systems. 9-Pin Mini-Type Receptacle J Wiring ( J9 wiring not available for circuit) Same Polarity Same Polarity 9 5 Visit our website: An appropriate female connector with cable (9N--F9AF--) is available on page -- in Connection Systems. 5-5

32 0T Modifications and Accessories Front View Cavity Mounting 0T -AO with 0T -WA Lever Manifold Mounting Rear View 0T -AMU with 0T -WA Lever Cavity Mounting Except for the types identified by Cat. Nos. 0T--B, 0T--, 0T--WS, 0T--WS, and 0T--CW, Bulletin 0T switches can be supplied in a special construction for cavity mounting in a machine base or panel. With this construction, the actuator and contact block are mounted on the back of a gasket steel plate. To order a switch for cavity mounting, add the letter O to the cat. no. of the corresponding surface mounted switch. Example: 0T--A becomes cat. no. 0T--AO (shown). Manifold Mounting All two-circuit Bulletin 0T switches canbesuppliedwithaspecialbase which permits mounting the switch manifold style on a machine base, panel or raceway. This base is equipped with a wiring hole and synthetic rubber gasket on the back (see illustration). To order a switch with a manifold mounting base, add the letter U to the cat. no. Example: 0T--AM becomes cat. no. 0T--AMU (shown). Transparent Cover Switches can be furnished with a gasket, transparent plastic cover. This modification enables the electrician to inspect terminal wiring without removing the switch cover. Not available on cat whisker, time delay or cavity style mounted limit switches. To order a switch with a transparent cover, add the letter Z to the cat. no. of the switch. For example: 0T-- becomes 0T--Z. Extended Temperature Operation Bulletin 0T nonplug-in limit switches are designed to operate in a temperature range of C (0 +0 F). Special limit switches modified for extended temperature operation C ( F) are available. Note: Temperature ranges below 0 C (+ F) are based on the absence of freezing moisture or water. To order a Bulletin 0T modified for extended temperature operation, insert the letter E after the operating head designation. Example: 0T--A becomes 0T--AE. (Cat. Nos. 0T--WS, WS, CW, P, P and the time delay limit switches are not available for extended temperature operation. Cat. Nos. 0T--A and A are available for extended temperature operation except with a reduction in damping.) Special Conduit Positions ual operating head switches can be obtained with up to three conduit openings. The location of conduit openings A, B, and C are illustrated in the dimension drawing on page 5--. The conduit opening in Position A is / in. NPT, the conduit openings in Position B and C are / inch NPT. To order a switch with special conduit positioning, add the suffix S, S or S to the cat. no. per the following: S=Position A+B S=Position A+C S=Position B+C Neon Indicating Lights (-Circuit Models Only) Two circuit Bulletin 0T surface mounted limit switches can be supplied with two neon indicating lights AC 0/0V, 50 0 Hz and 0V, 50 0 Hz. To order, add the letter N for 0V or N5 for 0V before the lever designation. Example: 0T--A with indicating lights would be 0T--AN. Not available on -circuit devices. In addition, indicating light kits as shown in the table below are available for field installation on two circuit devices. Limit Switch Construction Surface Mounted Light Kit 0V AC 50 0 Hz 0/0V AC 50 0 Hz 0T- N 0T- N Neutral Position 0T- N 0T- N0 Conduit Seal A synthetic rubber conduit seal is available to protect the conduit opening against entry of oil and moisture. The seal can be added easily before switch installation and should be installed so that the 5/ inch diameter projection (the other projection is / inch diameter) faces against the shoulder at the bottom of the pipe tap. The seal can accommodate up to four wires of # gauge or smaller. Each wire hole in the seal has a thin inner wall which is pierced when a wire is passed through. Thus, any unused opening remains sealed. The seat is designed for single contact block, surface mounted base limit switches having / inch conduit openings.
