70156-4117

Optical Sensors are a type of electronic sensor that uses optical components as input or output components in the automatic control system. Photoelectric Sensors, Industrial Sensors are widely introduced in applications ranging for recognition, position detection, and counting. One optical sensor is the 70156-4117 model, which falls into the categories of photoelectric and industrial sensors.

Overview

The Allen-Bradley 70156-4117 is an adjustable beam Photoelectric Sensor, with an 8 to 30 VDC voltage rating. This particular model is designed as an \'ampoule\' type, with a robust, usable construction. It is also built on a chassis-mountable package.

Optical Characteristics

The 70156-4117 has a maximum of 30m detection range and stands 1.87 inches (47mm) in height. It is also designed to operate in ambient lighting conditions of up to 8500 Lux, which makes it suitable for a variety of applications. Additionally, it has a typical response time of 1.2ms at a distance of 20mm and a frequency response range of 0.1 to 60 kHz. The optics are also adjustable, making this model especially versatile.

Electrical Characteristics

The 70156-4117 is built around an integrated NPN or PNP output. It has a maximum current draw of 50mA and requires an 8 to 30 VDC voltage input. Also included is a sensitivity adjustment switch, which enables users to fine-tune the sensitivity of the sensor for their particular application. Furthermore, the sensor also has a low-current leakage threshold of 0.35 mA.

Applications

Due to its robust construction and adjustable optics, the 70156-4117 is suitable for a wide variety of applications. Some of its current uses include position sensing, counting, and object recognition in industrial automation systems. It is also widely used in automotive, food, and beverage processing, as well as material handling systems.

Working Principle

The 70156-4117 utilizes a photoelectric sensor to detect objects and other signals. A photoelectric sensor works by transmitting a light beam, usually either laser or LED operated. The light is then contained within an adjustable optical range, and when an obstruction is present within the range, the beam is reflected away from its source. This triggers the output of the sensor, which is then used to activate other processes within the automation system.
