The SRBP binary and analogue sensor box is used for status display and for electrical feedback of the end positions of semi-rotary drives. The field of application for the sensor box extends from the hygiene-oriented food industry to exterior applications in the petrochemical industry. SRBP avoids shutdowns caused by faults and reduces the loss of production capacity through timely diagnostics and warnings. A rotary movement is converted into a switching output signal and displayed via a mechanical indicator. Its robust casing and modular design enable it to be combined with Festo drives.
