Optek Reflective Optical Sensor OPB720B-06Z, Open Collector Output, 1-Channel, 152mm Sensing Distance

The Optek OPB720B-06Z is a high-performance reflective optical sensor designed to offer robust object detection in industrial, automation, and process control scenarios. This sensor combines a reliable open collector output with a one-channel design, supporting secure signal interfacing for real-time detection of objects, position, or presence on automated lines.

With a maximum peak sensor distance of 152mm, the OPB720B-06Z allows for flexible placement and accurate detection across various target types, including reflective and interruptive modes. It is sensitive enough to recognize objects as small as 2mm, ensuring adaptability in environments where precise component or product movement is critical.

This sensor integrates hysteresis for output stability, greatly minimizing unwanted switching oscillations. As a result, responses remain consistent - keeping your system’s operation steady even with varying target materials or ambient lighting conditions. The OPB720B-06Z benefits from excellent ambient light rejection, which is vital for consistent readings in environments with variable illumination.

The compact construction (27.94mm height, 8.38mm width, and 17.15mm length) facilitates installation in space-constrained panels or retrofit situations. The unit features a 3-pin setup with a standard 990mm cable, simplifying connections and allowing for flexible routing in dense control cabinets.

Engineered for operation between 0°C and 70°C, the OPB720B-06Z performs reliably in standard industrial and laboratory environments. Its compliance with RoHS standards ensures suitability for regulated manufacturing and electronics sectors, while its durable design extends operational lifespan even in repeated-use cycles.

This reflective optical sensor is part of the OPB720 series, offering compatibility with a broad spectrum of system setups in electronics manufacturing, packaging lines, laboratory automation, and robotics. It is particularly useful for object sensing in conveyors, presence detection in automated assembly stations, and for monitoring position or edges in high-mix industrial lines.
