DFRobot SEN0448 4-Wire Slot Type Photoelectric Switch integrates an optical transceiver module, providing stable performance and strong anti-interference ability. The detection range of the module is 5mm (slot width). This photoelectric switch features an indicator onboard for feeding back device status in real-time. The 4-wire interfaces of the module feature IP50 protection level and can be freely switched between normally open and closed status. This photoelectric switch also features short-circuit protection, overload protection, and reverse connection protection mechanisms. The 4-wire slot type photoelectric switch operates at the 10VDC to 30VDC power supply range and 500Hz switching frequency. This switch is ideal for distinguishing transparent objects, detecting high-speeding moving things, or counting materials.
