SUBMINIATURE SIZE LIMIT SWITCHES QL (AZ4) Micro Limit Switches High precision micro limit switches with excellent environment proofing Quickly upgraded to limit switches with lamps by mounting an LED lamp socket An exposed terminal type model combined with a socket with cord for the built-in LED lamp (sold separately) easily become a limit switch with lamp. Convenient for maintenance such as operations checks. QL exposed terminal type QL limit with lamp Socket with LED lamp LED lamp L socket type (roller arm) Compliance with RoHS Directive FEATURES 1. Subminiature design The size of the actual unit is approximately 1/10 in the case of the plunger model and approximately 1/6.5 in the case of the arm model, that of the vertical type limit switch. Large-scale miniaturization has been achieved. Ideal for miniaturized machinery designs or highly accurate miniaturized machines. Approx. 1/10 r Plunger model Vertical type QL 2. A lamp can be easily added for operations checks 3. 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. O.T. exceeded Appropriate range Insufficient O.T. range Appropriate range Operating display board O.T. exceeded 4. Terminal uses both solder and tab (#110) 5. O.P. accuracy of ±0.2 (O.P. repeated accuracy initially ±0.03) achieved Attachment accuracy improved greatly The plunger model has achieved a high O.P. repeated accuracy of within 0.03mm 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.) Also, through a unique mechanism that permits adjustment of the O.P. in each individual product at the time of assem- bly, an O.P. accuracy of ±0.2mm .008inch can be safeguarded between lots, so that almost no operating position adjustment is required during either attachment or replacement. 6. A 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 107 times and a long electrical life of min. 3  105 times (5A, 250V AC 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. 8. A mechanism with excellent environment proofing • A 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 epoxy-sealed mechanism. Also, the entire mechanism is water-proof due to the optional socket. Socket with cord type... IP64 equivalent • A 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. TYPICAL APPLICATIONS Any application where compactness, density, and robustness, such as subminiaturized machines and plant machinery, is required. PRODUCT TYPE 1.

L socket type 1) After loosening the L socket fastening screws, grasp the terminal cover and pull it away from the switch body. 2) Remove the fastening screw from the terminal block. (Remove with the 3 terminal receptacle.) 8) After 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.) 2. Socket with cord (including socket with lamp) 1) Apply the rubber packing over the terminals, then insert the socket with cord into the switch body. Pull away from the body. Turn counterclockwise. 9) Temporarily screw in the fastening screw through the terminal body, then insert the washer and rubber bushing into the cord opening of L socket. Tighten it with a wrench or pliers. Terminal receptacle 3) Loosen the hexagonal nut and remove the rubber bushing and washer from the inside. 2) Screw the socket fastening screw into the switch body and tighten it. Turn counterclockwise. 4) Select cord from applicable wire table. 5) Decide which direction the cord outlet is to face and strip the sheath accordingly. (See page 43.) 6) After passing the applicable cord through the hexagonal nut, bushing, and washer in that order, pass the cord through the terminal case. 10) Apply the rubber packing over the terminals, then insert the L socket into the switch body. Clockwise direction Mounting 11) Tighten the fastening screw into the switch body. 7) After 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. The QL micro 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. Operating position (O.P.)

CAUTIONS 1. Ambient conditions 1) The use of these switches under the following conditions should be avoided. If the following conditions should become necessary, we recommend consulting us first. • Use where there will be direct contact with organic solvents, strong acids or alkalis, or direct exposure to their vapors. • Use where inflammable or corrosive gases exist. 2) Because these switchies are not of water resistant or immersion-proof construction, their use in water or oil should be avoided. Also, locations where water or oil can normally impringe upon the switch or where there is an excessive accumulation of dust should be avoided. 2. Wiring 1) Although QL limit switches have large over-travel (O.T.), excessive O.T. will occur wear and change in its 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. 2) Use their own accessories when mounting and wiring QL limit switches so as to maintain their own characterisrics. 3) In order to maintain the reliability at a high level under practical conditions of use, the actual operating conditions should be checked for the benefit of the quality of the product. 4) Do not use the switch in a silicon atmosphere. Case should be taken where organic silicon rubber, adhesive, sealing material, oil, grease or lead wire generates silicon. 5) Avoid use in excessively dusty environments where actuator operation would be hindered. 3. Socket with LED 1) The OFF condition leakage current at each voltage is as follows. Rated operating voltage 6V 24 to 48V DC 12V DC 6V DC 12V 24V 48V – – 1.6mA 3.2mA – 2.6mA 5.2mA – 2.5mA 5.6mA – – 2) Even the polarity of power source is connected in the opposite way, LED is not broken. However, LED is not lit on. All Rights Reserved © COPYRIGHT Panasonic Electric Works Co., Ltd.
