Optical sensors are widely used in industrial, engineering and scientific applications. The 70156-2238 sensor is a photoelectric type of optical sensor which is used to detect objects passing in front of the sensor. The sensor has a number of features and advantages that make it suitable for a variety of applications.

Design

The 70156-2238 photoelectric sensor has a light source, typically an infrared LED, that illuminates an object in front of the sensing area. The light is then reflected back to a receiver, usually an array of phototransistors, which is able to detect the presence of the object. The unit is designed like a bullet with the light source at one end and the receiver at the other, so that the unit has an extended sensing range.

The sensor has a chrome-plated steel base and is made from durable plastic with a special strain relief ring to ensure that it can withstand the rigours of industrial applications. The unit is supplied with a plastic mounting bracket for easy installation onto the production line.

Features and Benefits

The 70156-2238 is a reliable and accurate sensor that is quick to respond. It has a detection range of up to 15 metres and is resistant to dust, moisture and other environmental factors. It has been designed to meet the high standards of industrial applications and is approved for use in a wide variety of circumstances.

The unit has a self-test feature which checks its own operation at intervals and trips the alarm system if it finds a fault. This helps to ensure reliable and accurate operations for all its sensing applications. It also has dust and splash resistance to meet the needs of many industrial applications.

The 70156-2238 has a long life cycle that is assured by an innovative design utilising the latest technology in optical sensing. It is also designed to be simple to use and set up, meaning that the user doesn’t have to have any specialist expertise in order to operate it. This makes it an ideal solution for those who need a low maintenance and reliable photoelectric optical sensor.

Applications

The 70156-2238 can be used in a variety of industrial applications. Its high sensitivity makes it suitable for applications such as detecting the presence of objects in a production line. It can also be used to sense the presence of a person or an object in a safety zone. It is also possible to use the sensor in more sophisticated applications such as detecting the presence of smoke or hazardous materials.

Other applications include level monitoring, object counting and position sensing. The sensor can also be used in outdoor applications such as in security systems for detecting the presence of people or vehicles. Its long sensing range is particularly suitable for these types of applications.

Working Principle

The 70156-2238 works on the principle of emitting a light beam from its light source and detecting any reflections of this beam from any object in the sensing area. When a reflection of the light beam is detected, the unit trips its alarm system to indicate the presence of an object. The unit is very sensitive to small changes in the level of reflected light, making it very suitable for detection applications.

Conclusion

The 70156-2238 photoelectric optical sensor is a reliable and well designed unit with a range of benefits and features. It is ideal for use in industrial, engineering and scientific applications where a reliable and accurate detection of a presence or absence of an object is required. The sensor is dust and splash resistant and is designed to give a long service life. Its easy setup and self-testing feature makes it an ideal solution for those who require a maintenance free solution to their optical sensing needs.
