DBI5U-M18E-AP4X3 is a TURCK inductive sensor with a built-in rotation speed monitor. It counts the pulses from metal targets or teeth on a shaft and compares the rate with a reference set on a potentiometer: below the set speed the output is on, above it the output switches off.
- Monitoring range: 3...3000 rpm (0.05...50 Hz), set by potentiometer; switching distance 5 mm, flush mounting
- Start-up delay: fixed 5 s after power-on, so the drive can run up without a false alarm
- Output: PNP, NO, 3-wire, max. 200 mA; short-circuit, wire-break and reverse polarity protection
- Supply: 10...65 VDC, no-load current 20 mA
- Housing: M18 x 1 chrome-plated brass, PBT sensing face, thread length 65 mm, nut torque max. 25 Nm
- Environment: IP67, operating temperature -30...+85 °C
- Connection: 2 m PVC cable, 3 x 0.34 mm², Ø 5.2 mm
Used to detect a slipping belt, a stalled conveyor or a broken coupling, where the PLC only needs to know that a shaft is turning fast enough. A green LED shows power.
MTTF 874 years (SN 29500, 40 °C). Shock 30 g (11 ms), vibration 55 Hz (1 mm).
