Omron E2KQ-X DATASHEET

Inductive Proximity Sensor

E2KQ-X

Proximity Sensor with Easy Sensing
Distance Adjustment and Teflon* Coating
Effective Oil and Chemical Resistance

• Oil and chemical-resistant Teflon case.

• Sensitivity adjuster ensures easy sensing distance
adjustment according to the sensing object.

• Incorporates a cord connector with an indicator pro­viding high visibility.

* Teflon is a registered trademark of Dupont Company and Mitsui Du-

pont Chemical Company for their fluoride resin.
