Eaton Cutler-Hammer E51DP5 Photoelectric Head Series B2

The Eaton Cutler-Hammer E51DP5 Photoelectric Head (Series B2) is a dedicated sensing head used in industrial automation to detect the presence or absence of objects by means of a photoelectric beam, serving as the primary optical input for automated control loops. As the optical sensing element in a control system, it provides a clear signal when the beam is uninterrupted or interrupted, enabling reliable triggering of downstream equipment and facilitating synchronization with other sensors and actuators. The E51DP5 supports two supply options—120 VAC or 10–30 VDC—allowing flexible integration with diverse power architectures and simplifying installation alongside existing sensors, controllers, and safety devices within a single automation cabinet. Being part of the Eaton Cutler-Hammer product family, this head is designed for automation and control applications that require dependable optical detection within industrial environments. The E51DP5 designation identifies it as a Series B2 component within Eaton's lineup of photoelectric sensing heads, helping ensure compatibility with other Cutler-Hammer sensors and control hardware during system design and maintenance.
