Overview
The Eaton 12155AD07 is a precision photoelectric sensor receiver from the Prism Series, designed for thru-beam sensing applications requiring extended range and high noise immunity. This tubular receiver features a 20 ft sensing distance with a visible red beam, making alignment and setup straightforward for maintenance and installation crews. As the receiver component of a thru-beam pair, the 12155AD07 operates in dark-activate mode with isolated solid-state relay output, providing reliable non-contact detection for packaging, material handling, and industrial automation systems.
Key Features
- 20 ft thru-beam sensing range with high optical gain for dust and dirt resistance
- Visible red sensing beam for easy visual alignment and troubleshooting
- Dark operate / isolated solid-state relay output configuration
- Adjustable gain control for peak optical performance across varied applications
- 3 ms response time for fast detection and equipment response
- Compact 18 mm (0.71 in diameter) tubular shape for space-constrained mounting
