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: The polarization directions of the Filters are offset by 90° to prevent interference. When you install the Emitter and
Receiver, install them at the same angle to maintain this offset.
