OMRON D4E-1E21N Product information and technical parameters:
Brand: OMRON
Name: Small closed limit switch
Model: D4E-1E21N
Type: screw terminal type, general type with cable.
Rated current; 0.1A AC125V.
Drive rod: sealing horizontal ball plunger type.
Terminal: screw terminal with cable (right hand side).
Action indicator: no operation indicator.
Compared with D4E performance is stronger, in compliance with the requirements of high durability, high sealing.
Horizontal spring, with improved swing lever ratio of the built-in switch to provide a smooth action effect and a longer period of use.
Protection cover protects built-in switch from dust and oil pollution damage.
The plunger type combined with the solid sealing cover has longer service life.
