Mounting 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 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 0.20 to 0.39 N * m (3 to 5 kgf * cm). The maximum tightening torque is 0.39 N * m (5 kgf * cm). Mounting and Replacing the Operating Part Removing and Mounting the Operating Part 1. Remove the operating part as shown in the following diagram. If the operating part cannot be removed by hand, use the A3PJ-5080 Extractor. Panel Mounting nut Case Thread Operating section Lock ring Edge 2. To attach the operating part, push until it clicks into place. Removing the Lamp Removing from the Operating Part End Switch Mounting Lamp Snap on the Switch Unit to the Pushbutton Unit. Make sure the the Switch Unit is in the proper orientation when snapping on to the Pushbutton Unit. Grip the Lamp with the A16Z-5080 Extractor and pull to remove. Removing from the Switch Unit End The Lamp can be removed by hand once the Switch is removed using the A16Z-5080 Extractor. Installing the Lamp Switch Removal Grip the part between the Switch holder of the case and the Switch Unit using the A16Z-5080 Extractor, and pull to remove the Switch Unit. When mounting the Lamp, make sure it is facing the direction shown in the following diagram. Insert the Lamp while matching the protruding part of the Lamp and the small guides on the outer surface of the case. Protruding part The Lamp can be mounted from the operating part end by using the A16Z-5080 Extractor. The lamp can be mounted by following the opposite procedure for removing the Lamp. A16Z-5080 Extractor 15 A16 / M16 A16 / M16 Precautions ! 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 Mounting The A16 allows both a general-purpose load (125 V at 5A, 250 V at 3 A) and a microload. If a general-purpose load is applied, however, the microload area cannot be used. If the microload area is used with a general-purpose 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) 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 0.20 to 0.39 N * m (3 to 5 kgf * cm). 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 will touch 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. Microload area Invalid area Current (mA) LEDs The LED current-limiting resistor is built-in, so internal resistance is not required. Rated voltage Internal limiting resistor 5 VDC 33 Operating Environment 12 VDC 270 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. 24 VDC 1600 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. 16 Area of use General-purpose load area 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. If the panel is to be finished with coating, etc., make sure that the panel meets the specified dimensions after the coating. A16 / M16 A16 / M16 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.
