Optical Sensors - Photoelectric, Industrial

70156-2947 is a type of optical sensor that is used in a variety of industrial and commercial applications. Optical sensors are devices that transform light into electrical signals that are either on or off. Optical sensors are used for a multitude of tasks, such as monitoring machinery, safety, process control, and detection.

70156-2947 is an industrial grade photoelectric sensor. A photoelectric sensor is an optical device that uses light to detect objects or changes in the environment. The 70156-2947 is an LED-based photoelectric object detector that is designed to detect changes in a given light source. It is used in industrial applications such as food processing, packaging, and material handling.

The 70156-2947 is a two-part device. The first part is the emitter, which is composed of an LED light source, a photo diode, and associated circuitry. The emitter is mounted on the side of the machine or in the environment, where it emits a light beam that is interrupted by the object being detected.

The second part of the sensor is the receiver, which is composed of a photo transistor, associated circuitry, and a light shield. The receiver is mounted at the other end of the machine or environment from the emitter. The receiver\'s photo transistor is used to detect the light emitted from the emitter. When the light is interrupted, an electrical signal is generated, which is then processed and analyzed by the sensor\'s circuitry.

The 70156-2947 has a sensitivity of 0.3 to 0.6 mA, and it can detect objects up to 4 meters away. It is rated for a maximum operating voltage of 12 VDC and a maximum operating current of 14 mA. It is also compatible with 5 to 24 VDC power supplies.

The 70156-2947 is designed to be resistant to environmental conditions such as vibration, dust, and temperature. It is constructed with an IP67 rating (IP67 is a rating system used to classify the degree of protection provided by electrical enclosures), and it has an operating temperature range of -10° to +60°C (14° to 140°F).

The 70156-2947 is a versatile optical sensor that is well-suited for a wide range of industrial and commercial applications. It is a reliable, robust, and easy-to-use sensor that is designed to provide precise detection of objects in complex environments.
