OPB370N55 is an optical sensor in the slot type photointerrupters type family. This type of optical sensor uses a built-in amplifier and a transistor output to produce a signal output. The OPB370N55 is primarily used for shaft or slit sensing in automation and factory automation applications.

The photointerrupter has two parts, the emitting part (or the light emitter) and the receiving part (or the light receiver). The emitting part sends out an infrared light signal that is received by the receiver part. When there is an interruption to the light signal from a thing moving across some gap, it triggers a signal to report a change in status of the object.

The OPB370N55 is available in three versions; slot, slit and wheel-like slits. The slot variations have a gap between the emitter and receiver parts that is the width of a slot. The slit version has a gap that is the width of a slit. The wheel-like slit variation has a wheel slice that makes the gap in the slot version bigger. The structure of the wheel-like slit version allows for the faster revolution and higher accuracy.

The OPB370N55 has a built-in amplifier circuit to detect and confirm a change in signal status. The signal from the emitter is received by the receiver, amplified and then transferred to the output transistor to provide a digital signal indicating a change in status.

The OPB370N55 is made with a high-sensitivity, low-sensitivity structure to ensure high-accuracy detection within a 0.2mm (0.079 inch) gap at a 10-volt operating voltage. The sensor is capable of detecting automatically a change in status regardless of whether it is an open or closed status.

The OPB370N55 is specified for use in an industrial and commercial environment. It is commonly used for sensing and position detecting in factory automation systems to sense moving parts, detect rotational and linear movement, detect changes is object size and count object views.

It can also be used for a variety of machine safety and automation systems. It is ideal for applications such as edge detection, sheet-feeding systems, continuous-sheet feeding systems, pass-through detection, and spacers between objects. It is also employed for sensing moving robots and conveyer systems for factory automation.

OPB370N55 utilizes an extremely reliable and low power consumption photointerrupter system that is highly durable and can operate in a wide temperature range. This means that in varying conditions or temperature the OPB370N55 continues to be precise and accurate.

In leveraged markets, the strong sensing features of the OPB370N55 makes it the perfect choice for sensing paper, engine valves, fabric, and all kinds of card-like objects. The OPB370N55 is also widely used in the beverage industry, snack and raw food retailing systems, manufacturing automation, monitoring applications, vehicle detection, fluid level sensing, medical applications, security systems and more.
