OMRON D4E-2B21N Manual And Instructions
D4E-2B21N datasheetPDF datasheet
OMRON D4E-2B21N Product information and technical parameters：
Brand: OMRON
Name: Small closed limit switch
Model: D4E-2B21N
Type: screw terminal type, micro load with cable.
Rated current; 0.1A AC125V.
Driving rod: 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.
One touch off connector wiring operation miscellaneous,
And reduce the downtime due to wiring and maintenance.
Gold Plated minimum load type is an ideal choice for electronic control.
Can provide terminal type plastic screw terminal system and terminal type plastic with operation indicator.
Certified by EN, UL, CSA and CCC (China Standard) standard.
Install the pitch and with the characteristics of D4E- - N and D4E.
