005933 Issue 4 SNDH-H SERIES Speed Sensors DESCRIPTION FEATURES The SNDH-H Series Hall-Effect Solid state, non-contacting Hall-effect Speed Sensors uses a magnetically magnetic sensing allows the device biased Hall-effect integrated circuit to the ability to sense through dust, dirt accurately sense movement of ferrous and debris, enhancing reliability and metal targets. The specially designed product life IC (integrated circuit) and a permanent Air gap up to 2,5 mm allows the sensor magnet are sealed in rugged, probe- to be located up to 2,5 mm away from type packages. The flux density of the target the permanent magnet alters when High frequency switching capability approached by ferrous metal. This is (to 15 kHz) allows the device to handle detected by the Hall ICs. If the sensor high RPMs (SNDH-H3L-G01) is positioned at the circumference of O-ring seal allows device to be sealed a revolving gear wheel, for example, it into housings detects the teeth and tooth spaces, Two housing materials allow flexibility supplying a digital pulse output within the application: stainless steel with frequency proportional to gear (corrosion and rust resistant): SNDH- wheel speed. Optimum performance H3L-G01 plastic: SNDH-H3C-G04, Zero speed versions indicate that the is dependent upon variables which SNDH-H3P-G01 rotation has stopped, allowing the must be considered in combination: Various probe lengths (20,3 mm, device to work at extremely low RPMs target material, geometry and speed, 27,5 mm, and 40 mm) simplify use (SNDH-H3L-G01, SNDH-H3C-G04, sensor/target gap, and environmental within the application SNDH-H3P-G01) temperature. High operating temperature of -40C Stable performance over temperature to 125C (SNDH-H3P-G01 and SNDH- range and air gap range POTENTIAL TRANSPORTATION H3C-G04) allows the device to be used APPLICATIONS in high temperature applications (e.g., PORTFOLIO Transmission speed sensing in heavy engines) The SNDH-H Series joins the duty trucks, buses,agriculture and Digital current sinking output SNG-S Series, the LCZ Series, construction machines (open collector) simplifies electrical and the ZH10 Series Hall-Effect Speed Wheel speed detection in material interfacing to control systems.
