Useful 8-unit detection
Optical transmission-type Anti
Interference feature
The Anti Interference feature prevents false operation
due to mutual interference even if up to 8 units are
installed adjacently.

Easy-to-understand stability function
When four consecutive detections with a received light level of
120% or lower of the activation level have occurred, the stability
output is activated. At the same time, the stability indicator flashes
an alert.
Timer operation
A delay timer of about 40 ms is provided to allow for a
range of input conditions of the connected devices.
The timer is also useful for stabilization of detection output
such as canceling signal chattering.
Turbo function increases detecting distance
by 30%
When it is desirable to increase the detecting distance for
the current condition of use, enabling the turbo function
allows a distance increase of about 30%.
