1 SUMINITURE SIZE LIMIT SWITCHES QL (Z4) Limit Switches High precision micro limit switches with excellent environmental protection. Quickly upgraded to limit switches with lamps by mounting an LED lamp socket. FETURES. Subminiature design The size of the actual unit is approximately /0 in the case of the plunger model and approximately /6.5 in the case of the arm model, that of the Z5 Limit Switch. Large-scale miniaturization has been achieved. Ideal for miniaturized machinery designs or highly accurate miniaturized machines.. lamp can be easily added for operations checks n exposed terminal type model combined with a socket with cord for the builtin LED lamp (sold separately) easily become a limit switch with lamp. PRODUCT TYPE Convenient for maintenance such as operations checks. QL exposed terminal type Socket with LED lamp. With appropriate O.T. range display The arm model has a convenient appropriate O.T. range display for attachment adjustment work. This should be set so that the operations display board s indicated protrusion winds inside the protrusion on the axle receptor, permitting use under optimum conditions. 4. Terminal uses both solder and tab (#0) 5. O.P. accuracy of ±0.mm (O.P. repeated accuracy initially ±0.0) achieved ttachment accuracy improved greatly. The plunger model has achieved a high O.P. repeated accuracy of within 0.0mm through the development of a unique switch mechanism and a standard attachment surface on the upper surface of the unit (a surface with no slants.) lso, through a unique mechanism that permits adjustment of the O.P. in each individual product at the time of assembly, an O.P. accuracy of ±0.mm.00inch can be safeguarded between lots, so that almost no operating position adjustment is required during either attachment or replacement. 6. subminiature limit switch with a great stroke margin (O.T./T.T.) The T.T. has been enlarged by using a switching mechanism by coil spring for QL. 7. Long life The unit has a long mechanical life of minimum 0 7 times and a long electrical life of min. 0 5 times (5, 50V C resistance load) by means of a silver alloy contact with excellent solvent-proof characteristics and a guaranteed wiping operation that possesses two hinges and switching method by coil spring.. mechanism with excellent environmental protection protective construction equivalent to IEC IP64 The actuator has an axle seal with special packing, and the main case and terminals have both a waterproof ring and an epoxysealed mechanism. lso, the entire mechanism is water-proof due to the optional socket. Socket with cord type... IP64 equivalent sturdy, shockproof construction The body uses die-cast zinc, and the actuator uses stainless steel. Moreover, shock absorbers have been added to lessen the shock during plunger release.

Remove the from the terminal block. (Remove with the terminal receptacle.) Pull away from the body. 7. fter the terminals have been properly crimped in the terminal body, insert the body into the terminal case. (When inserting the body, be careful not to block the hole for the fastening screw with the wires.) ttaching the socket with cord. pply the rubber packing over the terminals, then insert the L socket into the switch body. Turn counterclockwise. Terminal receptacle. Loosen the hexagonal nut and remove the rubber bushing and washer from the inside. Turn counterclockwise.. Temporarily screw in the fastening screw through the terminal body, then insert the washer and rubber bushing into the cord opening. pply the hexagonal nut and tighten it with a wrench or pliers.. Screw the socket into the switch body and tighten it. 4. Decide which direction the cord outlet is to face and strip the sheath accordingly. 5. fter passing the applicable cord through the hexagonal nut, bushing, and washer in that order, pass the cord through the terminal case. 6. fter stripping the cord sheath, insert the corresponding wires into the grooves of the terminal body up to the wire stop, then crimp the terminal receptacle over the wires with a pair of pliers. 9. pply the rubber packing over the terminals, then insert the L socket into the switch body. 0. Tighten the into the switch body. Clockwise direction Mounting The QL Limit Switch is manufactured with a very small variation in the distance between the datum plane and the operating point. When the operating point has been accurately established and the mounting position clearly determined, two M4 bolts should be used securely fastening the switch.

CUTIONS. lthough QL limit switches have large over-travel (O.T.), excessive O.T. will cause wear and change the switch s characteristics. Specifically, where there is a need for long life, it is recommended that the proper O.T. should be used.. When the operating object is in the free condition, force should not be applied directly to the actuator.. Use QL accessories when mounting and wiring QL limit switches to maintain proper characterisrics. 4. In order to maintain high reliability under practical conditions of use, the actual operating conditions should be checked periodically. 5. The use of these switches under the following conditions should be avoided. If the following conditions should become necessary, we recommend consulting the factory. Use where there will be direct contact with organic solvents, strong acids or alkalis, or direct exposure to their vapors. Use where flammable or corrosive gases exist. ecause these switches are not of water resistant or immersion-proof construction, their use in water or oil should be avoided. lso, locations where water or oil can normally come in contact with the switch, or where there is an excessive accumulation of dust, should be avoided. 7.
