70156-2696

Optical sensors are a type of sensor device that detect energy in the form of light in order to measure presence, absence, and a variety of physical properties. They are an important part of industrial automation, and the 70156-2696 is a common industrial optical sensor.

The 70156-2696 is a miniature version of the standard photoelectric sensor, which in this case has been equipped with a fibre optic LED and a miniature phototransistor. This sensor features maximum flexibility by being suitable for both near and far detection applications. It can detect objects from 5mm to 500mm away. It is also suitable for the detection of black, non-metallic objects. This sensor also has NPN and PNP outputs to fit a variety of applications.

The 70156-2696 can be used in a variety of industrial applications including inspection and sorter machines, flowmeter control, and small parts inspection. It is also used in the protection of heavy machinery by using an interlock system. Its flexibility and compatibility with both NPN and PNP outputs make it an attractive option for many industrial automation applications.

The working principle behind the 70156-2696 is that a beam of infrared light is transmitted from the LED across a gap between a transmitter and a receiver. When the beam is interrupted by an object, the receiver will detect the absence of the beam and send a signal to the control unit. The signal will then trigger a response, such as the stopping of a machine, or an output from the machine. The beam can be either pulsed or continuous, depending on the application.

The 70156-2696\'s versatility makes it a popular choice for industrial automation applications. With its long detection distance, compatibility with both NPN and PNP outputs, and ability to detect black, non-metallic objects, the sensor is a reliable choice for a variety of industrial automation needs.
