Laser beams are harmful to the human eye. Never look into the laser beam directly or through optical instruments. Mounting bracket and reflective models are also supplied with a reflector. Mini-Beam SM312 series sensors are self-contained, DC-powered sensors. This Mini-Beam SM312 series features compact, high-performance sensors with an 18-mm threaded lens. The SM312 series is ideal for registration mark detection, baggage handling, and bottle conveyor applications. Expert models are available with push-button learning mode configuration. Plastic housing options include M18 front nose mount or screw mount. Push-button or remote programming is available, along with automatic, precise sensitivity adjustments at low contrast. The sensors feature bipolar output with on-light/on-dark functions and multi-function LEDs for easy adjustment and monitoring. Full electrical protection is included. Optionally available modes include opposed, transparent plastic opposed, polarized, non-polarized reflective, convergent, and diffuse.
