Balluff BES 516-377-EO-C-05 Through-Beam Photoelectric Sensor

Balluff BES 516-377-EO-C-05 is a compact inductive proximity sensor in an M8x1 cylindrical housing, measuring Ø8 x 45 mm and designed for flush-mount installation in tight spaces. As part of Balluff's BES01LF family, it provides a normally closed PNP switch output with a sensing range of 1.5 mm, enabling reliable metal-target detection without contact. The 516-377-EO-C-05 variant maps to the BES01LF ordering code, a designation Balluff lists in its catalogs and price references to ensure the same form factor and output configuration across the inductive sensor lineup. Note that despite the product title mentioning a through-beam photoelectric sensor, this model is an inductive sensor, not a through-beam emitter-receiver configuration. With its small footprint and flush-mount compatibility, it is suited for confined automation tasks where metal presence or proximity needs to be sensed at short range.
