BWI Eagle Signal 10-7139 Proximity Sensor Switch

The BWI Eagle Signal 10-7139 Belt Sensor Proximity Sensor Switch is a proximity switch in the Eagle Signal product family, identified by model number 10-7139, designed to sense the presence or position of a belt in belt-driven equipment without contact. As a belt sensor, it delivers an electrical signal to control circuits when the sensing event occurs, enabling monitoring, interlocks, or automated responses in conveyor or belt-related machinery. The description notes the MSHA designation alongside the 10-7139 model, helping link this part to its identifying code within maintenance and replacement part references. This combination of model identity and sensing type supports accurate part matching for repairs or retrofits that rely on Eagle Signal proximity sensor switches.
