Balluff BGL 5A-007-S49 Fork Sensor PNP NO NC

Balluff BGL0021, sold as the BGL 5A-007-S49, is a compact metal fork light barrier designed for precise presence sensing of small parts in automated lines. The standard fork opening is 5 mm, and the unit measures 10 x 25 x 54 mm with a zinc die-cast housing that is painted and a glass sensing surface for durability in harsh environments. It uses an infrared through-beam optical principle with a divergent beam and a light exit via an M8x1 3-pin connector, supporting a PNP output configured as normally open or normally closed (NO/NC) and operating from 10 to 30 V DC Ub. The device is CE and UKCA certified, with cULus and WEEE registrations, reflecting Balluff’s compliance with global safety and environmental standards. As part of Balluff’s fork sensor family, this model is well-suited for metal-part detection in applications such as assembly lines, conveyors, and packaging where a small, reliable fork gap is required to verify part presence or position.
