The Autonics BM3M-TDT1,2 is engineered as an Economical General-Purpose Photo Sensor with a through-beam sensing type, offering a 3m detection range. Using a 940nm infrared LED, it ensures consistent detection of opaque objects as small as Γ8mm, even under strong ambient light up to 11,000lx. With a rapid 3ms response time, it supports conveyor systems, automated assembly, and packaging lines that require precise and repeatable object detection.
Operating on 12β24VDC, the BM3M-TDT1,2 consumes a maximum of 45mA across emitter and receiver, providing efficiency and compatibility with PLCs and control systems. The sensor outputs via an NPN open collector and works in Dark ON mode, reducing configuration complexity. Its robust ABS case, polycarbonate optics, and steel hardware ensure durability, while the IP-rated design supports stability in dusty and humid shop-floor conditions. The 2m Γ4mm pre-wired cable simplifies installation, making it dependable for engineers and maintenance teams.
Applications for the BM3M-TDT1,2 include object counting in packaging plants, position sensing on conveyors, and part verification in assembly lines. OEMs and integrators value its affordability and reliability, while students and junior engineers benefit from its practical design for training in automation principles. Supplied through wholesalers, dealers, and distributors, it remains a trusted solution for Indian industries needing dependable sensors.
With its balance of performance, durability, and affordability, the Autonics BM3M-TDT1,2 strengthens the Photoelectric Sensors lineup, serving both production and learning environments.
