The Allen Bradley 42SMR-7001 is designed as a miniature rectangular photoelectric sensor that excels under various conditions. It features a remarkable sensing distance of 9.2 meters (30 feet) and functions efficiently with an operating voltage between 10–30 VDC. This sensor is optimized for versatility with a selection of sensing modes: standard diffuse, wide-angle diffuse, fixed-focus diffuse, ClearSight, retroreflective, and polarized retroreflective. This flexibility allows it to adapt to many environments and requirements.

A significant feature is the inclusion of a 5-turn clutch-protected potentiometer for sensitivity adjustment, ensuring precise configuration. The unit incorporates a visual indication of status through a single red LED, providing clear operational feedback to users. For connectivity, options include a 3-meter cable or a Micro Quick Disconnect (Micro QD) for streamlined installation.

The field of view can be configured to either 2° or 8°, depending on the specific receiver setup, allowing for tailored detection strategies. With a rapid response time of 500 microseconds, this sensor is equipped for high-speed detection tasks. It utilizes various light sources, including visible red LED, visible green LED, and infrared LED to suit different applications.

Constructed from durable industrial-grade plastic, the housing is designed to withstand challenging conditions while maintaining a compact profile for easy integration into constrained spaces. Finally, the sensor offers NPN or PNP transistor output types, providing compatibility with various control systems.
