The Autonics BM1M-MDT is a compact and economical retroreflective photoelectric sensor designed for reliable object detection within a 1-meter sensing range using a standard reflector (MS-2). Equipped with a 940nm Infrared LED and operating in Dark ON mode, it provides precise detection of opaque targets as small as Ø60mm. The sensor responds quickly with a maximum response time of 3ms, ensuring efficient operation in high-speed automation tasks. Its fixed sensitivity eliminates manual adjustments, simplifying setup for consistent factory use.
The BM1M-MDT operates on a stable 12–24VDC power supply (±10% ripple tolerance) and consumes just 40mA, making it energy-efficient for long-term deployment. It features a reliable NPN open collector output and a durable 2-meter Ø4mm cable for secure and quick installation. Built with high-quality materials—like an ABS case, acrylic sensing window, and steel mounting hardware—this model is engineered to withstand ambient conditions ranging from -10°C to 60°C and up to 85% relative humidity.
This sensor is widely used in assembly lines, packaging units, conveyor systems, and pick-and-place machines where reliable object presence or absence detection is critical. Indian plant maintenance teams favor the BM1M-MDT for its affordability, robust construction, and hassle-free integration with control systems. For junior engineers and automation students, it serves as an easy-to-use entry point into sensor-based industrial control. To discover more from the brand, visit the Autonics brand page.
