The OPB804 is a non-contact optical switch from Optek Technology, part of TT electronics plc. This device features an NPN silicon phototransistor and an infrared Light Emitting Diode (LED) positioned across a 0.155-inch (3.94 mm) slot. The opaque plastic body is designed to minimize ambient light interference, making it suitable for general applications. Its wide aperture enhances versatility.
The LED emits in the near-infrared spectrum, ranging from 850 to 940nm. The switch is designed for PCB mounting and operates within a temperature range of -40°C to +85°C. Key electrical specifications include a forward voltage typically 1.25V at 20mA, a collector-emitter breakdown voltage of 30V, and an on-state collector current of at least 0.5mA at 10V VCE and 20mA IF.
Applications for the OPB804 include non-contact object sensing, assembly line automation, machine automation, equipment security, and machine safety. Its design makes it a reliable component for various industrial and automation systems requiring precise object detection.
