BH Series

M18 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.
