The SSCF210300 Detector Switches BI-DIR 71.4gf SCREW manufactured by ALPS is a gallium-arsenide (GaAs) infrared LED switch designed to be used in automotive and industrial sensing applications. The device includes an array of infrared LED’s and phototransistors that detect the presence of an object. It is designed for low power consumption and is resistant to water and abrasion. The LED switch is robust enough to work in environments where temperatures range from -40°C to 125°C. It is also available with an integrated analog-to-digital converter (ADC) for precise position detection. The device has a built-in 2.54mm pitch connector, which is compatible with most industry standard connectors and enables easy installation.
