standexelectronics.comDatasheet Rev CED Page 1 +1 970.879.9900 | sensorsales@standexelectronics.com S18-SSTHS1-R5SA5-30 Magnet Detecting Speed Switch  Moving Magnet Actuated Speed Switch, 55 Gauss sensitivity  Transistor output for Over or Under Speed  Regulated input, NPN with 5k pull-up  Stainless 18x1mm x 53mm housing  Shielded 4 wire 22 AWG 80°C PVC, 5ft Part Description: S 18 - SSTHS 1 - R 5 SA 5 - 30 ‘South Pole Magnet Actuated Speed Switch with Transistor Output’ Overspeed, Underspeed, Zero-Speed

DESCRIPTION

  • Speed switch output turns on/off dependent on factory programmed frequency.
  • 30 Hz switch point will activate the output at any speed where 30 or more magnets pass the sensor within 1 second. Contact us for lower or higher switching speeds.
  • Single channel digital square wave output for resolving actual speed.
  • Detects the South Pole field from permanent magnets using Hall Effect Technology
  • Detects south pole fields of 55 Gauss or more. Operate gap range dependent on magnet size/type
  • No orientation required. Use lock nuts to set air gap within range of target

To convert RPM (Revolutions per Minute) to Hz, you need to know the target’s pulses per revolution, “N”. A target with 2 S pole magnets will produce 2 pulses per revolution, so N=2. Hz = RPM * ( N / 60 ). Or RPM = Hz * ( 60 / N). Example: Using 2 magnets and a 30 Hz trip point, RPM = 30 * (60 / 2) so the output switches low at 900 RPM.
