TE / Jaquet Speed Sensor — DSF 1410.00 SHV Ex-atex (5 m)
MPN: 374Z-05254
Manufacturer: TE Connectivity / Jaquet
Drawing number 111496F1
Hall-effect single-channel speed sensor for hazardous areas. Produces a square-wave frequency proportional to rotational speed when paired with a ferromagnetic pole wheel. Intrinsically safe, maintenance-free design for harsh environments (oil, grease, vibration).
- Hall-effect single channel, push-pull square-wave output
- Supply 8–28 VDC, max ripple 25 mVpp
- Frequency range: 0.05 Hz to 20 kHz
- Short-circuit and reverse-polarity protected
- Stainless steel housing (1.4305), hermetically sealed face
- Ingress protection: IP68 (head), IP67 (cable)
- Shock 20 g/20 ms; vibration 5 g (5–2000 Hz)

Typical Applications
Turbomachinery, rotating equipment in oil & gas, industrial drives, and process control systems in hazardous areas.
- Mount sensor face centered over pole wheel; keep ≥3 mm from wheel edge under all operating conditions.
- Route sensor cable away from high-power conductors and large machines to reduce EMI.
- Set the smallest practical air gap that prevents contact during operation.
