This is a proximity sensor from Balluff's BES series of sensors. It has an inductive sensor, a PNP/NO output configuration, a 10÷30VDC power supply, IP67 protection, and an operating temperature range of -25 ÷ 70°C. It can detect objects that come within close proximity or touch the sensor surface, making it suitable for use with machine components, such as limit switches, safety barriers, and other safety sensors. The sensor is also suitable for use in harsh environments because it has an IP67 rating for protection against dust and water.
