SNDH-H Series, Hall-effect speed sensor, omnidirectional, plastic housing, 67 mm [2.64 in] barrel length, Bosch 928000453 connector

The SNDH-H Series Hall-Effect Speed Sensors use a magnetically biased Hall-effect integrated circuit to accurately sense movement of ferrous metal targets. The specially designed integrated circuit (IC) and a permanent magnet are sealed in rugged, probe-type packages.

The flux density of the permanent magnet alters when approached by ferrous metal. This is detected by the Hall ICs. If the sensor is positioned at the circumference of a revolving gear wheel, for example, it detects the teeth and tooth spaces, supplying a digital pulse output with frequency proportional to gear wheel speed.

Optimum performance is dependent upon variables which must be considered in combination: target material, geometry and speed, sensor/target gap, and environmental temperature.

Produkt Merkmale


  • Solid state, non-contacting Hall-effect magnetic sensing allows the device the ability to sense through dust, dirt and debris, enhancing reliability and product life
  • Air gap up to 2,5 mm [0.098 in] allows sensor to be up to 2,5 mm away from target
  • High frequency switching capability (to 15 kHz) allows the device to handle high RPMs (SNDH-H3L-G01, SNDH-H3C-G03, SNDH-H3C-G05, SNDH-H3C-G06)
  • O-ring seal allows device to be sealed into housings
  • Two housing materials allow flexibility within the application: stainless steel (corrosion and rust resistant): SNDH-H3L-G01; plastic: SNDH-H3C-G03, SNDH-H3C-G04, SNDH-H3C-G05 and SNDH-H3C-G06, SNDH-H3P-G01
  • Various probe lengths (20,3 mm [0.80], 24 mm [0.94 in] 27,5 mm [1.08], 40 mm [1.57 in], 46 mm [1.81 in], 67 mm [2.64 in] simplify use within the application
  • High operating temperature [-40 °C to 150 °C (-40 °F to 302 °F)] (SNDH-H3C-G03, SNDH-H3C-G05, SNDH-H3C-G06) allows the device to be used in high temperature applications (e.g., engines)
  • Digital current sinking output (open collector) simplifies electrical interfacing to control systems
  • Multiple connector options (Bosch 928000453, Delphi-Packard Metripak 150.2 Type 101, Deutsch DT06-3S) simplify installation
  • Omnidirectional capability eliminates the need to align the sensor to the target, allowing the user to simply bolt the device (SNDH-H3C-G0, SNDH-H3L-G01)
  • Zero speed versions indicate that the rotation has stopped, allowing the device to work at extremely low RPMs (SNDH-H3L-G01, SNDH-H3C-G04, SNDH-H3P-G01)
  • Stable performance over temperature range and airgap range
