Balluff BGL 50A-005-S49 Fork Sensor

Balluff BGL 50A-005-S49, order code BGL001P, is a 50 mm fork-shaped photoelectric slot sensor designed for precise gap detection in compact automation. It provides a single digital output (PNP/NPN, NO/NC selectable) from a 10–30 V DC supply with a yellow status LED and light-on/dark-on configuration, and it operates from a nominal 12/24 V supply. The rugged die-cast zinc housing with a glass sensing surface is IP67-rated, and it includes M4 through-holes for mounting as well as a 3-pin M8 connector for wiring. With a 640 nm red beam and adjustable sensitivity via two potentiometers (270° range each) and a maximum switching frequency around 5 kHz, this sensor suits conveyor, packaging, and assembly-line applications requiring reliable fork sensing across a 50 mm gap.
