Strip a length of 10 mm off the end of the wire (allowable range: 101 mm). 2. Bunch wire strands together and straighten them. 3. Insert the wire into the insertion hole while pressing the release button at the side of the hole. (Using a precision screwdriver is recommended.) 4. Let go of the release button to lock the wire into place. 5. After locking, pull on the wire gently to confirm that it is securely locked. Removing Wires Remove wires by pulling them while pressing the release button. Note: When reusing wires that have already been locked, cut off the end of the wire and strip the wire again before using. Mounting Precautions 1. The mounting panel thickness must be 0.5 to 3.2 mm. 2. The mounting ring must be tightened to a torque 0.29 to 0.49 Nm. 3. The mounting hole must be cut out in the way described previously. The dimension A is the length required for removing the Switch when it is in the mounted state. If Switches are mounted side-by-side separated by less than the specified distance, it may not be possible to remove the Switch. 4. Be sure to mount the Case to the Switch with the correct orientation. Mount with the * mark on the Case facing in the same direction as the side of the Switch with the direction arrow or the word TOP. TOP mark Direction arrow * mark Case 5. 6. 7. 8. * mark Switch Case Switch When using stranded wires with the Screw-Less Clamp, wrap the ends of the wires together first. When wiring, insert the wires until they come into contact with something. After wiring, pull on the wires to check that they are secure. After wiring, ensure that continuous pressure is not applied to the terminals. Be sure to perform wiring correctly. Refer to internal connections diagrams and check the terminal numbers before wiring. 65 A16 A16 Nomenclature Color of Pushbutton * Pushbutton LED/incandescent models Red, green, yellow, white, blue * Cap Neon models Red, green, white * Non-lighted models Red, green, yellow, white, blue, black Legend plate Dispersion plate Degree of Protection * IP40/Oil-resistant IP65 Reflective plunger Flange Shape Lamp Rectangular (A16j-J, A16j-3J) Switch * Square (A16j-A) Round (A16j-T) Terminal Type * * * 66 Solder terminals (tab terminals #110) PCB terminals Screw-Less Clamp Switch Ratings 5 A at 125 VAC 3 A at 250 VAC 3 A at 30 VDC Minimum applicable load: 1 mA at 5 VDC A16 A16 Dimensions Note: All units are in millimeters unless otherwise indicated.

WARNING Do not apply a voltage between the incandescent lamp and the terminal that is greater than the rated voltage. If the incandescent lamp is broken, the operating part may pop out. Always turn OFF the power and wait for 10 minutes before replacing the incandescent lamp. If the lamp is replaced immediately after the power is turned OFF, the remaining heat may cause burns. Correct Use The A16 allows both a standard load (125 V at 5A, 250 V at 3 A) and a microload. If a standard load is applied, however, the microload area cannot be used. If the microload area is used with a standard load, the contact surface will become rough, and the opening and closing of the contact for a microload may become unreliable. The minimum applicable load is the N-level reference value. This value indicates the malfunction reference level for the reliability level of 60% ( 60) (conforming to JIS C5003). The equation, 60 = 0.5 x 10-4/time indicates that the estimated malfunction rate is less than 1/2,000,000 with a reliability level of 60%. Voltage (V) Mounting Always make sure that the power is turned OFF before mounting, removing, or wiring the Switch, or performing maintenance. Do not tighten the mounting nut more than necessary using tools such as pointed-nose pliers. Doing so will damage the mounting nut. The tightening torque is 0.29 to 0.49 Nm. Wiring Solder terminals and quick-connect terminals (#110) are commonly used for terminals. Be sure to use electrical wires that are a size appropriate for the applied voltage and carry current (conductor size is 0.5 to 0.75 mm2). Perform soldering according to the conditions provided below. If the soldering is not properly performed, the lead wires will become detached, resulting in short-circuits. 1. Hand soldering: 30 W, within 5 s 2. Dip soldering: 240C, within 3 s Wait for one minute after soldering before exerting any external force on the solder. Use non-corrosive resin fluid as the flux. Make sure that the electric cord is wired so that it does not touch the Unit. If the electric cord touches the Unit, then electric wires with a heat resistance of 100C min. must be used. After wiring the Switch, maintain an appropriate clearance and creepage distance. Operating Environment Area of use Invalid area Current (mA) LED The LED current-limiting resistor is built-in, so internal resistance is not required. Rated voltage Internal limiting resistor 5 VDC 33 (82 ) 12 VDC 270 (470 ) 24 VDC 1600 (2400 ) The IP65 model is designed with a protective structure so that it will not sustain damage if it is subjected to water from any direction to the front of the panel. Note: Using the Microload Others Insert a contact protection circuit, if necessary, to prevent the reduction of life expectancy due to extreme wear on the contacts caused by loads where inrush current occurs when the contact is opened and closed. The oil-resistant IP65 uses NBR rubber and is resistant to general cutting oil and cooling oil. Some particular oils cannot be used with the oil-resistant IP65, however, so contact your OMRON representative for details. The values in parentheses are for models with blue Pushbutton Units. 77 A16/M16 A16/M16 If the panel is to be finished with coating, etc., make sure that the panel meets the specified dimensions after the coating. Do not subject the Switch to extreme shock or vibration. Doing so will cause malfunctions and damage to the Switch. Do not let sharp objects come into contact with the Switches that are made of resin. Doing so will damage the Switches, causing scratches on the outside of the operating parts, and malfunction. When handling the Switches, do not throw or drop them. Do not allow the Switch to drop and hit the ground. Do not place or drop heavy objects on the Switch. Do not operate the Switch with hard or sharp objects. Hammer Screwdriver ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937.
