OPB940W51Z is a Logic Output type Photointerrupter slot type device that can be used in a range of application fields. It detects the presence of an object or the target to trigger a specific action. This Photointerrupter is capable of providing an out signal when the target is in its slot and an in signal when the target is moved out of the slot. It can be used in tasks such as release and activation of machines.

The working principle of OPB940W51Z is fairly simple. It has an infrared light source like an LED which is situated on one side of the slot. On the other side of the slot, there is an IR detector placed that detects the presence of the target. The IR transmitter plays a very important role in this device as various parameters depend on it. The gap between the transmitter and receiver of the same should be around 0.4mm and the light intensity should be 3mW/sr or less.

The slot width of this photo interrupter can range from 1mm to 10mm. It consists of a slimline body which helps in the partial slot sensing applications. Depending upon the application field, the wire connect limits may range from 4 wire (3D) 2.5mm to 6 wire (4D)2.4mm. The package of the OPB940W51Z can be SMPS (surface mount) type or TH (through hole) type.

It has a wide operating temperature range of -25℃ to +85℃ making it suitable for a lot of application fields. The response time of this device is ≤2.3ms making it very fast in triggering the specific actions. The narrow slot size of 1-10mm helps in obtaining data from a small range of objects ranging from small to large.

Its compact size helps it to fit in a small space and is known for its reliability and low power consumption. All the electrical terminals are fully insulated and fully covered against dust and dirt. This device has a high degree of optical isolation which is around 5000V. The maximum rated voltage is AC/DC 120V with a current of 0.7A.

The OPB940W51Z has a wide range of application fields. It can be used in home automation, medical equipment, human detection and automobile applications. It can be used as a switch for opening and closing automatic doors. It can also be used in the printing industry, fax machines, vending machines, ATMs, copiers and many other applications. It can also be used in motion sensing security systems where it activates alarms or signals when an intruder passes through its vision slot. Pick and Place application, slot followers, length measuring systems and many other applications.

OPB940W51Z is a great device as it has a wide range of applications and has a good degree of reliability. Its fast response time and low power consumption make it ideal for use in a wide range of application fields.
