Product Description
Product Overview
The OPB750 and OPB755 series are non-contact reflective object sensors designed for assembly line and machine automation. They feature a reflective assembly with an LED and phototransistor output optimized to reduce low-level light while maintaining high-level light gain. These sensors are suitable for applications such as machine safety, end-of-travel detection, and door sensing, offering a high contrast ratio and a low-cost plastic housing.
