Honeywell SNDH-H Series

DESCRIPTION
The SNDH-H Series Hall-Effect Speed Sensors uses 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. Optimum performance is dependent upon variables which must be considered in combination: target material, geometry and speed, sensor/target gap, and environmental temperature.

POTENTIAL TRANSPORTATION APPLICATIONS

Transmission speed sensing in heavy duty trucks, buses,agriculture and construction machines
Wheel speed detection in material handling, agriculture, and construction machines
Motor speed sensing in vehicle powertrain and hybrid engines in heavy duty trucks, buses, agriculture and construction machines. Not recommended for Aerospace or Defense applications.

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 allows the sensor to be located up to 2,5 mm away from the target
High frequency switching capability (to 15 kHz) allows the device to handle high RPMs (SNDH-H3L-G01)
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-G04, SNDH-H3P-G01
Various probe lengths (20,3 mm, 27,5 mm, and 40 mm) simplify use within the application
High operating temperature of -40°C to 125°C (SNDH-H3P-G01 and SNDH-H3C-G04) 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 air gap range.
