The Autonics BS5-P1ML Push Button Type Photomicro Sensor is engineered for Light ON mode, where the output stays OFF when the button is pressed. Its infrared LED (940nm) ensures stable operation even under 1,000lx fluorescent light. The tactile button mechanism features a 4.0 Β± 0.5mm switching point and a max. 3N operation load, providing accurate detection for human-triggered actions or fixture confirmations.
Powered by a 12β24VDC Β±10% supply and consuming only 35mA, the NPN open collector output integrates easily with PLCs and control systems. The robust polycarbonate + glass fiber housing with SUS304 stainless steel sleeve offers mechanical strength, while the IP40 rating protects against dust ingress. The cable type (Γ3, 1m) connection allows quick installation in tight spaces. For the complete range, visit Autonics Sensors & Controllers.
In assembly plants, it ensures accurate part positioning checks before the next process stage. In packaging units, it acts as a reliable trigger for batch count confirmation or rejection mechanisms. Maintenance teams benefit from its durability and consistent actuation point, reducing calibration needs over time.
For reliable tactile input and long service life in industrial control systems, engineers trust the Autonics BS5-P1ML Push Button Type Photomicro Sensor.
