Safety Precautions

Refer to Safety Precautions for All Pushbutton Switches.

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.

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

•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: 350°C, within 3 s

2. Dip soldering: 350°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.

Operating Environment

•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 × 10-4/operations indicates that the

estimated malfunction rate is less than 1/2,000,000 operations with

a reliability level of 60%.

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.

•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.
