The Festo SRBS-Q12-6-E270-EP-1-S-M8 is an angular Hall effect position sensor built for the DRVS and DSM Size 6 rotary drive families. It reads a 270° electrical angle, outputting a 50 mA signal back to the controller over a 300 mm pigtail terminated in an M8 plug. The sensor body and connector are sealed to IP65 and IP68, meaning this unit handles washdown routines and even brief submersion without letting moisture into the electronics — a real plus out here in the grease where hoses get pulled across the line every shift.
Power and environment range
Runs on 10 to 30 VDC, so it plays nice with standard 24 VDC control loops. Operating temperature spans -20 to 70 °C, which covers most factory-floor conditions short of a foundry or oven zone. Screw mounting secures it to the drive frame — no DIN rail, no bracket kit needed; just align and fasten.
Peer comparison — same cable, same seal, different drive size
The SRBS-Q12-12-E270-EP-1-S-M8, SRBS-Q12-40-E270-EP-1-S-M8, and SRBS-Q12-16-E270-EP-1-S-M8 share every electrical and environmental spec — same 270° angle, same 300 mm cable, same M8 plug, same IP65/IP68 sealing, same 10-30 VDC supply and 50 mA output. The only difference is the drive size they're keyed for. The -6 variant mates to Size 6 rotary actuators; the -12, -16, and -40 variants fit their respective larger frames. If you're swapping a failed sensor on a Size 6 drive, this is the direct drop-in. No rewiring, no adapter, no panel modification.
