Recommended ferrules
Note: 1. Make sure that the outer diameter of the wire coating is
smaller than the inner diameter of the insulation sleeve of
the recommended ferrule.
2. Make sure that the ferrule processing dimensions conform
to the following figures.
Recommended Flat-Blade Screwdrivers
Use a flat-blade screwdriver to connect and remove wires.
Use one of the following flat-blade screwdrivers.
The following table shows manufacturers and models as of 2015/Dec.
* OMRON's exclusive purchase model XW4Z-00B is available to
order as SZF 0-0,4 x 2,5 (manufactured by Phoenix Contact).
•After wiring the Switch/Indicator, provide a sufficient insulation
distance.
The following information applies to both screw
terminal blocks and Push-In Plus terminal
blocks.
LED Lamps
•A current-limiting resistor is built in the LED lamp, so the
installation of an external resistance is not required. A diode bridge
is equipped in 6, 12, and 24 V specifications. As such, there is no
specific polarity. Use only AC power for 100 and 200 V
specifications.
•Lighting malfunction of the LED lamp
A micro-current of approximately 0.1 mA or less is sufficient to turn
on the LED lamps. Take a countermeasure like adding a resistor
to prevent mis-lighting in parallel to the LED lamp.
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.
Key-Type Selector Switches
•Make sure to insert the key to the bottom of the cylinder before
turning it.
Button Operation
•Do not rotate or pull on the button on a Mushroom Switch. The
button may come off, preventing operation.
