The Festo SRBS-Q12-8-E270-EP-1-S-M8 is an angular Hall effect position sensor built for DRVS and DSM Size 8 rotary drives. It reports the shaft angle over a 270° electrical range via a 50 mA output, powered from 10 to 30 V. The M8 plug with 300 mm cable and screw mounting makes it a direct-fit feedback component for those actuator families.
The 270° electrical angle covers the full rotation of the rotary drive it's paired with — you don't lose travel at either end. The IP65/IP68 rating means the sensor body and the M8 connector survive washdown and temporary submersion, which is the real test in a wet well or a food-grade line where hoses are the daily reality. The 50 mA output current is the signal level, not a load driver; it feeds directly into a standard PLC analog or digital input card. The 10-30 V supply range gives flexibility across 24 VDC control systems and lets it run on a 12 V backup bus if the panel has one.
