The Autonics BS5-P1MD is a precision-engineered Push Button Type Photomicro Sensor that uses a Dark ON output logic, activated when the button is pressed. It features a maximum operation load of 3N (0.3kgf), with an output switching position at 4.0 Β± 0.5mm, offering tactile reliability for detecting operator input or physical contact in machine setups. Its infrared LED (940nm) ensures stable signal performance, while its quick 1ms response time supports real-time automation decisions. Powered by a 12β24VDC Β±10% supply, it consumes just 35mAβsuitable for energy-conscious applications.
This model includes a NPN open collector output, enabling seamless integration with standard PLCs and control relays. Built with a cable-type connection and a robust polycarbonate + glass fiber housing, the sensor is both lightweight (approx. 50g) and durable. It operates reliably in temperatures from -20 to 55β, with IP40 protection against dust and accidental contact. The mechanical structure includes stainless steel sleeves (SUS304), ensuring a long operational life under repetitive mechanical actuation. This makes the BS5-P1MD a reliable choice in environments where touch-based sensing and rugged actuation are necessary.

The Autonics Push Button Type Photomicro Sensor BS5-P1MD is ideal for use in manual inspection jigs, operator-guided assembly processes, and safety input zones in packaging lines or testing stations. Its physical button interface offers reliable feedback in environments where optical or proximity sensors are not practical. Engineers prefer it for confirming part presence during mechanical insertion tasks or for initiating localized commands in compact control enclosures. If your machine requires tactile confirmation with reliable switching, you can depend on the Autonics BS5-P1MD.
