Sensing Object Material E2K-F can detect almost any type of object. The sensing dis- 40mm 50mm 50mm tance of E2K-F, however, will vary with the electrical charac- teristics of the object, such as the conductance and inductance of the object, as well as the water content and ca- Close mounting possible Face-to-face mounting pacity of the object. The maximum sensing distance of E2K-F will be available if the object is made of grounded metal. Effect of High-frequency Electro-magnetic Field There are objects that cannot be detected indirectly.

For a typical measure, refer to theNois with Common pre- Effects of Surrounding Metal cautions of a photoelectric sensor in Rear B-page. Separate E2K-F from ambient metals as shown below. Wiring Considerations 30mm The characteristics of E2K-F will not change if the cord is ex- tended. Keep in mind that voltage drops may occur due to the cord extension, thus, ensure that the total cord length does 60mm 45mm not exceed 200 m.
