Honeywell SNDH-T4C-G0 Speed Sensor Hall
DESCRIPTION
The SNDH-T Series is a dual differential Hall-effect sensor that provides
speed and direction information using a quadrature output with signals 90°
phase shifted from each other. Target direction is determined by output
lead/lag phase shifting. This product is designed for applications where
extremely high resolution is required at wide frequency ranges, 1 Hz to 15
kHz, and large air gaps. BiCMOS (bipolar complementary metal-oxide-
semiconductor). Hall-effect technology, using advanced digital signal
processing for dynamic off-set cancellation, provides enhanced air gap
performance and phase shift accuracy over most conditions.
Unique patented (pending) IC (integrated circuit) packaging provides output
phase shift tolerancing with enhanced accuracy. The robust package is
automotive under-the-hood grade for most environmental conditions, as well as
EMI (electromagentic interference) hardened. Multiple connection options are
available. Package design includes an O-ring seal for pressure applications
and a fixed mounting flange.

- Speed and direction of gears and shafts in transmissions, hydraulic motors, pumps and gearboxes
PORTFOLIO
The SNDH-T Series is part of a portfolio of electronic speed and position
sensors that use a variety of technologies to detect speed, direction, or
position of a moving ferrous metal or magnetic target.
