DESCRIPTION

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 IC (integrated circuit) 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.

FEATURES

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 to302 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

DESCRIPTION

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 IC (integrated circuit) 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.
