The Eaton Cutler Hammer E51DEL Through-Beam Photoelectric Sensor Head & Body is a two-piece through-beam photoelectric switch designed for non-contact object detection in automation. In a through-beam configuration, the sensor uses a separate head and body to project and detect a light beam, and it provides a switched output when the beam is interrupted. As part of the E51DEL family, this head-and-body assembly enables beam sensing across a defined gap in automation equipment where precise presence or absence detection is needed.
