Snap on the Switch Unit to the Pushbutton Unit. Mounting to the Panel Insert the Pushbutton Unit into the front of the panel, and fix the lock ring and mounting nut from the terminal side. Make sure that the Switch Unit has the correct orientation when snapping it onto the Case. Align the • mark on the Case with the groove between the case guards on the NC terminal side of the Switch Unit in the way shown below, and push the Switch Unit into the Case until it clicks into place. Confirm that the Switch Unit is securely in place before using. Make sure that the lock ring is aligned with the thread of the Case and the edge of the lock ring is touching the panel. Tighten the mounting nuts to a torque of 0.29 to 0.49 N⋅m. • mark The maximum tightening torque is 0.49 N⋅m. Panel Mounting nut Case Thread Groove between case guards NC terminal Lock ring Edge Mounting the Switch Unit for Voltage Reduction Types 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 N⋅m. 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.

A16Z-5080 Extractor Removing from the Switch End The Lamp can be removed by hand once the Switch is removed using the A16Z-5080 Extractor. • A16-P Models (with PCB Terminals) Installing the Lamp The Switch Unit can be mounted or dismounted by simply opening or closing the lever. ■ Mounting and Replacing the Pushbutton Protruding part The Lamp can be mounted from the Pushbutton end by using the A16Z-5080 Extractor. The lamp can be mounted by following the opposite procedure for removing the Lamp. Removing and Mounting the Pushbutton 1. Remove the Pushbutton as shown in the following diagram. If the Pushbutton cannot be removed by hand, use the A3PJ-5080 Extractor. Pushbutton 2. To attach the Pushbutton, push until it clicks into place.

Note: Recommended panel thickness: 0.5 to 2 mm. Precautions 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 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 N⋅m. Wiring The IP65 model is designed with a degree of protection so that it will not sustain damage if it is subjected to water from any direction to the front of the panel. Using the Microload 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 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% (λ 60) (conforming to JIS C5003). The equation, λ 60 = 0.5 x 10–4/operations indicates that the estimated malfunction rate is less than 1/2,000,000 operations with a reliability level of 60%. Solder Terminal 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. Pushbutton Switches !WARNING Operating Environment Voltage (V) Refer to the Technical Information for Pushbutton Switches (Cat. No. A143). Area of use Invalid area 1. Hand soldering: 30 W, within 5 s 2. Dip soldering: 240°C, 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 100°C min. must be used. After wiring the Switch, maintain an appropriate clearance and creepage distance. Current (mA) LED The LED current-limiting resistor is built-in, so internal resistance is not required. Rated voltage Internal limiting resistor Screw-Less Clamps 5 VDC 33 Ω (82 Ω) Mounting Procedure 12 VDC 270 Ω (470 Ω) 24 VDC 1600 Ω (2400 Ω) 1. Strip a length of 10 mm off the end of the wire (allowable range: 10±1 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. Note: The values in parentheses are for models with blue Pushbutton Units. Others 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. Removing Procedure 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. Pushbutton Switch A16 G-33 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.
