Partly Order Discontinued as of August 31, 2012 COMPACT SIZE LIMIT SWITCHES VL (AZ8) Mini Limit Switches A compact and accurate vertical limit switch. Type with a lamp which makes maintenance convenient; either a neon AC powered lamp or an LED DC powered lamp. The cable can either be screwed in directly, or can use U-shaped and circular pressure terminals. Inner construction Cover attachment screw Cable Cover Terminal screw Cord vent Body Construction permits lamp attachment method to be changed. Head block Standard type With lamps (Roller arm) 6. Lamp connection can be either spring type or lead wire type * Spring type (wiring unnecessary) (With neon or LED lamp type) Wiring is unnecessary because the lamp is directly connected to the terminals. By simply changing the direction of the lamp holder attachment, it is possible to display both lights during inoperability and during operation (however, if both N.O. and N.C. loads are connected, only the inoperability lamp can be displayed.) Operating lamp 4. Mounting are possible to both front and back Compliance with RoHS Directive FEATURES M4 attachment nut 1. Compact design approximately 1/3 of the AZ5 limit switches M4 attachment bolt Approx. 1/3 Spring washer r AZ5 type Inoperability lamp (with shipping) M5 attachment bolt VL 2. Au-clad contacts that can even use low level circuit and little chattering and bouncing The built-in switch has Au-clad contacts with excellent contact reliability and uses a crossbar contact method, and moreover, has a dual cutoff circuit (1 Form A 1 Form B contact) with little chattering and bouncing due to computer-operated analysis. 3. Easy wiring with full-open terminals When the cover is removed, the terminals are open as far as the flank, so the necessity to insert your fingers into a case to complete the wiring has been removed. Moreover, the wiring space is large despite the compact size, and the terminals are spread in a tiered array, so that wiring work can be completed very easily. Spring washer 5. Type with a lamp that can be used with a wide range of voltages * With neon lamp Compatible with: 100 and 200V AC ; Even at 100V AC, sufficient luminosity is achieved through the diamond-cut lens. Also with a long lifespan of more than 20 thousand hours. * With LED lamp Covers 6 to 48V DC and comes in three types, 6V DC , 12V DC , 24 to 48V DC Uses two highly luminescent LEDs and in addition, sufficient luminosity is achieved through the diamond-cut lens. * Lead wiring type (LED lamp type only) Because the wiring can be made parallel to the load, current leakage from the lamp can be reduced to 0. Even with a slight leak, the electronic circuit incurring the leak can be used safely. 7. Dust-proof, waterproof, oil resistant construction The main unit and the cover are sealed with rubber packing, and the cord runner is doubly sealed by the cord vent. The actuator is sealed by both a rubber cap and an O ring in all models. Also, the lens and cover are formed simultaneously with the lamp type, and moreover, a nameplate is affixed to the upper surface, thereby improving the already excellent waterproof capabilities. (Note: Applications directly involving the cord entrance and the locations which are always wet and oily, or submersion in water or oil, cannot be used.) TYPICAL APPLICATIONS Ideal for general plant facilities such as engineering machinery, conveyer machinery, and assembly lines LED lamp type is also compatible with low-voltage DC control circuits such as in PCs and computers.

Over travel (O.T.) 1) When overtravel is too large, life is shortened due to possible damage to the mechanism. Please use in the following appropriate range. Types Plunger (AZ8111, 8112, 8122) Roller Arm (AZ8104, 8107, 8108) Flexible Rod (AZ8166, 8169) Overtravel 1.5 to 2.0mm .059 to .079inch 20 to 30 15 to 20mm .591 to .787inch (at the top) 2. Ambient conditions 1) Because these switches are not of immersion protected construction, their use in water or oil should be avoided. Also, locations where water or oil can normally impinge upon the switch or where there is an excessive accumulation of dust should be avoided. 2) 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. 3) Use within an ambient temperature of -20 to +60C -4 to +140F. (However, do not allow it to freeze.) 4) 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. 5) If OT is too big, the life of limit switch will be shortened switching friction. Use it with enough margin of OT. 70% of OT standard value will be good for use. 6) 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. 7) When wiring, do not connect the lead wires directly to the terminals, but use the crimp terminals and tighten them to a torque of 0.39 to 0.59 N*m {4 to 6 kg*cm}. 8) Avoid use in excessively dusty environments where actuator operation would be hindered. 9) When used outdoors (in places where there is exposure to direct sunlight or rain such as in multistory car parks) or in environments where ozone is generated, the influence of these environments may cause deterioration of the rubber material. Please consult us if you intend to use a switch in environments such as these. 10) Do not store in places where organic gas might be generated or in places of high dust content or high humidity. 3. Installation 1) Tighten the three cover installation screws equally. Tightening torque is 0.2 to 0.29 N*m (2 to 3 kg*cm). 2) Avoid having extra cord length pushed into the cord vent. Any extra length when wiring should be allowed to rest in its natural position. All Rights Reserved (c) COPYRIGHT Panasonic Electric Works Co., Ltd.

Lamp holder 1) As shown in the photograph, wrench a minus-driver in the gap between the cover and the part of the indicator holder indicated by the arrow in the direction of insertion, and raise the lamp a little. 2) After removing the indicator holder, insert it in the reverse direction, and push it in until a snap is heard. 3) After changing the direction of the indicator holder, put the cover on it in such a way that the spring touches the top of the terminal screw. (Unless the spring rests completely on the terminal screw, distortion of the spring, failure in lighting of the lamp or short circuit may result.) 5. Spring type 1) When loads are connected to both N.O. and N.C. only the indicatin at nonoperation time can be used. 2) Take special care not to damage or deform the contact spring during change of indicator holder direction or during connection work. 3) In the case of VL limit switch with neon lamp, if the lamp is connected in series in a 100V circuit, the lamp ceases to be lighted. However, for a 200V circuit, up to 2 lamps can be connected in series. 6. Lead type 1) When loads are connected to both N.O. and N.C. indication can be given on both N.O. and N.C. sides, but it is impossible to connect the indication circuit to the load in series and parallel.
