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.

Sensitivity Adjuster Included

The attached sensitivity adjuster allows users to easily adjust the sensitivity without repositioning the sensors.

Various Status Indicators

Operation indicator (red LED) and stability indicator (green LED) allows users To quickly identify the operation status of the sensors.

IP67 Protection Structure

IP67 protection structure allows stable and error-free operation even in wet or dusty environments.
