SNDH-H Series Hall-Effect Speed Sensors DESCRIPTION If the sensor is positioned at the circumference of a revolving The SNDH-H Series Hall-Effect Speed Sensors use a gear wheel, for example, it detects the teeth and tooth spaces, magnetically biased Hall-effect integrated circuit to accurately supplying a digital pulse output with frequency proportional to sense movement of ferrous metal targets. The specially gear wheel speed. designed IC (integrated circuit) and a permanent magnet are sealed in rugged, probe-type packages. Optimum performance is dependent upon variables which must be considered in combination: target material, geometry The flux density of the permanent magnet alters when and speed, sensor/target gap, and environmental temperature. approached by ferrous metal. This is detected by the Hall ICs. FEATURES Solid state, non-contacting Hall-effect magnetic sensing Multiple connector options (Bosch 928000453, Delphi- Packard Metripak 150.2 Type 101, Deutsch DT06-3S) allows the device the ability to sense through dust, dirt and simplify installation debris, enhancing reliability and product life Air gap up to 2,5 mm 0.098 in allows sensor to be up to 2,5 Omnidirectional capability eliminates the need to align the sensor to the target, allowing the user to simply bolt the mm away from target device (SNDH-H3C-G0, SNDH-H3L-G01) High frequency switching capability (to 15 kHz) allows the device to handle high RPMs (SNDH-H3L-G01, SNDH-H3C- Zero speed versions indicate that the rotation has stopped, allowing the device to work at extremely low RPMs (SNDH- G03, SNDH-H3C-G05, SNDH-H3C-G06) H3L-G01, SNDH-H3C-G04, SNDH-H3P-G01) O-ring seal allows device to be sealed into housings Two housing materials allow flexibility within the application: Stable performance over temperature range and airgap range stainless steel (corrosion and rust resistant): SNDH-H3L- G01 plastic: SNDH-H3C-G03, SNDH-H3C-G04, SNDH- POTENTIAL APPLICATIONS H3C-G05 and SNDH-H3C-G06, SNDH-H3P-G01 Various probe lengths (20,3 mm 0.80 , 24 mm 0.94 in Transportation 27,5 mm 1.08 , 40 mm 1.57 in , 46 mm 1.81 in , 67 mm Engine camshaft and crankshaft speed 2.64 in simplify use within the application Transmission speed High operating temperature -40 C to 150 C (-40 F to Vehicle speed 302 F) (SNDH-H3C-G03, SNDH-H3C-G05, SNDH-H3C- Wheel speed G06) allows the device to be used in high temperature Pump speed applications (e.g., engines) Motor speed Digital current sinking output (open collector) simplifies Industrial electrical interfacing to control systems Flow meters and flow turbines Pump speed Motor speed SNDH-H Series Table 1.
