Balluff BLE 18MR-BS1LT-S4-C Bluetooth Low Energy Sensor

Balluff BLE 18MR-BS1LT-S4-C is a cylindrical M18 through-beam photoelectric receiver with a Bluetooth Low Energy interface, designed to pair with a companion emitter in through-beam configurations. It measures 20 x 85 x 28.5 mm and uses a brass, nickel-plated housing with a glass sensing surface, delivering durable performance in industrial environments. Operated from 10 to 30 V DC, it is available in PNP normally open or normally closed variants and connects via a 4-pin M12 connector. The red light beam provides a sensing range up to 50 m, making it suitable for long-range object detection on conveyors and automation lines. This BLE-enabled device carries CE, cULus, and WEEE certifications and is part of Balluff’s BLE 18MR family of sensors.
