Mutual Interference Prevention Filter

Dimensions	Model	Quantity	Remarks
	E39-E11	2 per Emitter and Receiver (4 total)	For use with E3ZS-T81A. This filter prevents mutual interference by changing the direction of polarized light of the 2 adjacent Emitter/ Receivers. However, when the filter is attached, the maximum sensing distance of the E3ZS is reduced to 1.5 m.

Note: Connect the Sensor to a safety controller conforming to related standards to use it as a safety device or as part of
         a safety system.
* Depending on the wiring, this may turn ON when light is interrupted.
   For your safety, be sure to connect the pink receiver wire (mode selection input) to 24 VDC to turn ON when light is
   incident.
