Autonics BUP and BMS Photoelectric Sensors
Slot-type through-beam and diffuse photoelectric sensors
Compact photoelectric sensors: the BUP-50S is a 50 mm slot-type through-beam sensor and the BMS300-DDT is a 300 mm diffuse-reflective sensor. Both use an infrared LED.
- BUP-50S: through-beam, 50 mm sensing distance, NPN open-collector output
- BMS300-DDT: diffuse reflective, 300 mm sensing distance
- Infrared LED (940 nm)
