Cutler-Hammer 1141D-6501 Photoelectric Through-Beam Sensor

The Cutler-Hammer 1141D-6501 is a 20 series photoelectric through-beam source. As the emitter in a through-beam sensor pair, this component provides the light beam that is monitored by the opposite-side receiver. When aligned with a matching Cutler-Hammer receiver, the 1141D-6501 enables beam interruption sensing along a fixed path, making it suitable for basic presence or position detection in automation layouts that require non-contact sensing. This model is specifically designated as the source, differentiating it from receiver units that detect the transmitted beam. The 20 series designation identifies its place within Cutler-Hammer's line of photoelectric sensors, ensuring compatibility with other 20 series emitters and receivers in the same system family. This through-beam source is designed to be paired with a corresponding receiver in the same 20 series family to form a complete sensing path.
