BH Series - Front/Side Mount Photoelectric Sensors
BH Series Front/Side Mount Photoelectric Sensors
The BH series photoelectric sensors are capable of front mounting using M18 nut and fastening cap or side mounting using M3 bolt screw and nuts. The flexible installation options allow easy application in various industrial settings. The sensors can produce individual or simultaneous NPN and PNP open collector outputs by simple wire configuration. The IP67 protection structure provides stable and error-free operation even in wet or dusty environments.

Front/Side Mounting Sensors
The BH series photoelectric sensors are capable of both front mounting (using M18 nut) and Side mounting (using M3 screws) for flexible installation in diverse applications.
Simultaneous NPN/PNP Open Collector Output
Depending on wire configuration, the sensors can produce individual NPN or PNP outputs Or simultaneous NPN and PNP outputs
Long Sensing Distance Up to 20m
The through-beam type models feature long sensing distances up to 20m.
Compact Size
The compact sized sensors (W14×H34.5×L28mm) can be easily installed in tight or limited spaces.
Mirror Surface Rejection (MSR) Function (Retroreflective Type)
The retroreflective type models feature built-in polarizing filters allowing the units to only receive light from reflectors.
This function allows stable detection of highly reflective targets including metals, mirrors, etc.

The Working Principle of Mirror Surface Rejection (MSR) Function : The light passed through the polarizing filter on the emitter will become horizontal. The light reflected on the retroreflective mirror will turn 90˚ and the vertical light will Be received by receiver through vertical polarizing filter. The light reflected from reflective targets will remain horizontal, and thus will not be received by the receiver with the vertical polarizing filter.
Sensitivity Adjuster Included
The attached sensitivity adjuster allows users to easily adjust the sensitivity without repositioning the sensors.
