Optical sensors are devices that detect and measure electromagnetic radiation (light and infrared for example). In its simplest form, optical sensors often consist of a semiconductor device such as a photodiode or an LED that converts the incident light into an electrical signal, which can be directly measured or used as a trigger for further processing. The 70156-4137 is an optic sensor that is used in many industries where automated processes, such as vision systems or robotic guidance systems, are important.

The 70156-4137 is a photoelectric proximity sensor that determines the presence of an object by measuring its proximity to the sensor. It works by emitting a beam of infrared light towards the object and measuring the reflected light from the object. The reflected light is analyzed to determine the presence and position of the object. This type of sensor is used in a wide range of applications, from industrial production lines to medical instrumentation.

The 70156-4137 has an operating range of up to three meters, making it suitable for applications that require longer ranges and more precise measurements. It is a reliable, rugged device and is temperature compensated for reliable operation in a wide range of ambient temperatures. The 70156-4137 is also shock and vibration resistant, providing long-term durability in hostile environments.

In terms of output types, the 70156-4137 provides both analog and digital outputs. The analog output can be used for traditional control applications, while the digital output can be used for direct control of logic functions. The device also has a built-in signal conditioning circuit that eliminates external components such as resistors and capacitors, saving space and cost. The device is powered by either a 12VDC supply or an external 4-20 milliamp source.

The 70156-4137 contains two detector elements: an infrared LED and a phototransistor. The infrared LED is used to provide a beam of infrared light to the object being monitored. This beam is then reflected off the object and picked up by the phototransistor. The level of the detected signal is then processed and used to determine the presence and/or position of the object.

The 70156-4137 is a versatile device that can be used in a wide range of applications in industries such as automotive, robotics, process control, and medical instrumentation. Its long-range detection, built-in signal conditioning, and digital and analog outputs make it an ideal choice for high-precision sensing applications. Additionally, its rugged construction and temperature-compensated design make it a reliable solution for applications in harsh environments.
