Wiring

• Terminal screws must be Phillips or slotted M3.5 screws with a

square washer.

• The tightening torque is 1.08 to 1.27 N·m.

• Single wires, stranded wires, and crimp terminals can be

connected to the Switch.

• Applicable Wiring Materials:

Twisted strands: 2 mm2 max.

Solid wire: 1.6 mm dia. max.

• After wiring the Switch, maintain an appropriate clearance and

creepage distance.

Operating Environment

• 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.

• The Switch is intended for indoor use only. Using the Switch

outdoor may cause it to fail.

LEDs

• The LED current-limiting resistor is built-in, so internal resistance is

not required.

• If commercially available LEDs are used, select the ones that meet

the following conditions:

Base: BA9S/13

Overall length: 26 mm max.

Power consumption: 2.6 W max.

When DC-specific LEDs are used, wire the Switch so that the X1

terminal is positive.

• Mis-lighting of the LED

The LED lights with approx. 0.1 mA or less of micro-current. Take

a countermeasure like adding a resistor to prevent mis-lighting in

parallel to the LED.

The micro-current varies with the machine (leak current or stray

capacity between cables, etc.). Select resistance value and

allowable power consumption that meet the actual current.

Using the Microload

Contact failure may occur if a Switch designed for a standard load is

used to switch a microload. Use Switches within the application

ranges shown in the following graph. Even within the application

range, 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 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 10−6/time indicates that the estimated

malfunction rate is less than 1/2,000,000 with a reliability level of 60%.

Others

• If the panel is to be coated, make sure that the panel meets the

specified dimensions after coating.

• Due to the structure of the Switch, severe shock or vibration may

cause malfunctions or damage to the Switch.

Also, most Switches are made from resin and will be damaged if

they come into contact with sharp objects. Particularly scratches

on the Operation Unit may create visual and operational

obtrusions.

Handle the Switches with care, and do not throw or drop them.
