Optical sensors are widely used in a range of applications from simple position sensing to complex machine control. Photointerrupters are one type of optical sensor, designed to detect the presence or absence of an object with the help of a light source and a photodetector. OPB980N51 is a type of photointerrupter, known as a Slot Type with Logic Output. This type of sensor consists of a transmitter and a receiver element that are angled to each other and separated by a small gap. When an object blocks the gap, the light from the transmitter element is not detected, thus triggering the logic output at the receiver.

The main purpose of the OPB980N51 is to protect machinery and provide overload protection from jamming, which can occur when materials become lodged or trapped between moving parts in the machine. Another common usage is when a safety appliance needs to be controlled. For example, when operating a window blind, if the operator wants to open the blind, but the blind is already lowered, the OPB980N51 can detect this and command the motor to stop. In addition, this sensor can also be used to detect objects that impede the movement of a machine, such as misplaced parts or objects blocking its path.

The OPB980N51 has a couple key features which make it an advantageous choice for machinery safety:

• Durability – made from durable materials, it can withstand exposures to extreme temperatures and dust, making it a reliable option for harsh environments.
• Easy installation – quick and simple installation, with no special tools or wiring required.
• High-logic output – the logic output is more sensitive than other types of photointerrupters, meaning a quicker response time.

The OPB980N51 works on a simple optical principle: when it detects that the gap between its transmitter and receiver element is blocked, it releases a logic output signal, triggering a connected device. This can be either a mechanical safety switch, contact block, or other device connected to the logic output of the OPB980N51 that turns off the machine when an object is obstructing it. The device also has an LED display which indicates if the sensor is detecting a blockage.

The OPB980N51 is a reliable and versatile sensor with a number of advantages, making it a great choice for applications requiring machinery protection. Its simple installation, high-logic output, and durability ensure reliable operation and improved safety for machinery.
