German KELLER HCW sensors, KELLER HCW models, KELLER HCW prices

KELLER HCW sensors are components that convert changes in non-electrical quantities (such as speed and pressure) into changes in electrical signals. Depending on the non-electrical quantity converted, they can be classified into pressure sensors, speed sensors, temperature sensors, etc., and serve as parts and accessories for measurement and control instruments and equipment. KELLER HCW sensor principle: Photoelectric sensors achieve control by converting changes in light intensity into changes in electrical signals. Generally, a photoelectric sensor consists of three parts: a transmitter, a receiver, and a detection circuit. The transmitter is aligned
