Optical Sensors - Photoelectric, Industrial

The 70156-4634 is an industrial-grade photoelectric sensor that has multiple uses for industrial applications. The device includes a light source, a receiver or detector made up of a light-sensitive material, a signal amplifier, and an output interface. It is suitable for a wide range of industrial applications, including material handling, machine tools, food production, automotive, robots, and packaging lines.

Working Principle

When the device is turned on, the light source emits a beam of infrared light that is received by the detector, usually located on the opposite side of the device. The detector can be made up of a photodiode, a photo-transistor, photoresistors, or a photovoltaic cell. When a light beam is interrupted, the detector switches state from ON to OFF. This causes a change in the voltage of the device, activating the output signal.

The output is typically an electrical signal that can be used to activate an output or turn on a relay, which is used to switch an input or output. Depending on the application, the output signal can also be used to control the speed of a motor, or to detect the presence or absence of an object. The electrical output can be a voltage, current, voltage or current switch, as well as an open collector or open drain signal.
