A photoelectric sensor, or photoeye, is a device used to detect the presence or absence of an object by using a light transmitter, often infrared, and a photoelectric receiver. The 70156-4497 photoelectric sensor combines the transmitter and receiver into one unit, making it much smaller than other photoeye applications. It is made up of two parts, an emitter and a receiver. The emitter emits an infrared beam that the receiver picks up. When nothing is present to interrupt the infrared beam, the receiver picks up the signal from the transmitter and the circuit is kept closed, but when an object is placed in the path of the beam, the receiver no longer detects the signal, the circuit is opened and the sensor triggers.

The 70156-4497 photoelectric sensor can operate in two different modes: ambient mode and fixed mode. In ambient mode, the receiver demodulates the infrared beam coming from the emitter when the beam is interrupted by an object. In fixed mode, the beam passes through a reflector and the receiver demodulates the beam when it is reflected back by the object. Reflectors are usually used in fixed mode to reduce the beam spread and focus the beam to a narrow target. This makes it easier to detect objects even when they are far away. Both modes can be adjusted to achieve a minimum detection range of up to 2 meters.

The 70156-4497 photoelectric sensor is designed for industrial applications such as position detection, material conveying, access control, entry protection, operator guidance, and many others. Its compact design makes it able to fit into tight spaces, making it ideal for most industrial applications. It can operate in the presence of dust, dirt, and other particles that may interfere with signal reception. The sensor is also shock-proof, designed to withstand vibration and shock up to an acceleration of 6.9 m/s². It can also be used in temperatures ranging from -40°C to 60°C.

The 70156-4497 photoelectric sensor is reliable and easy to install. It can be set up quickly and requires minimal maintenance. All of these features make it the perfect choice for applications where space is constrained and sensitivity and reliability are required. With its compact size and low power consumption, it is an ideal choice for industrial applications.
