OPB900W55Z

The OPB900W55Z from Optek is a slot type optical sensor, which uses a photosensitive device to detect objects. This sensor typically operates in industrial automation, allowing machines to sense when an object has passed a certain detection point in a production line. The sensor offers a logic output, allowing for fast response times and easy integration in electronic systems.

Physically, the OPB900W55Z consists of two parts — the body and the object barrier. The body contains the photosensitive element, which is a specialized component that emits light and detects any change in the amount of light that is received. The object barrier is a dark shield that blocks any external light from entering the device. When an object passes through the gap between the body and the object barrier, the photosensitive element is triggered, resulting in a logic output.

In operation, the OPB900W55Z emits a beam of light that is attenuated by the object barrier. When an object passes through the gap and interrupts the beam of light, the photosensitive element detects the change in the amount of light. This change in light level triggers the output of a logic signal, which can then be used to control a circuit, such as an alarm system or factory automation system.

The OPB900W55Z is a low-cost unit, which is ideal for applications requiring quick response times and accurate object detection. The logic output allows for easy integration in electronic systems and is available in either an NPN or PNP version. The sensor also has a wide operating temperature range, making it suitable for a variety of industrial applications.

Overall, the OPB900W55Z is a versatile optical sensor suitable for a variety of applications in industrial automation. It has a photosensitive element that detects any object interrupting the light beam, and provides a logic output for easy integration into electronic systems. With its low cost and wide operating temperature range, the OPB900W55Z is ideal for a variety of applications.
