The PE12E136 with Sensor: laser; Range: 5m; PNP/NPN/push pull; DARK-ON,LIGHT-ON is an electronic part manufactured by IPF ELECTRONIC. It is a device that utilizes a laser that can detect objects within 5m range. It has three output options including PNP, NPN, or push pull that can be used to trigger other components as a result of the sensing. Additionally, it has two operating modes – DARK-ON & LIGHT-ON. With DARK-ON, the device is triggered in the presence of light while with LIGHT-ON, the device is triggered in the presence of darkness. This part is designed for Long-distance detection, fiber-optic sensing, and a variety of demanding sensing applications.
