DESCRIPTION
The SNDH-T Series is a dual differential hall 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.
The robust package is automotive under-the-hood grade for
This product is designed for applications where extremely high
resolution is required at wide frequency ranges, 1 kHz 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.
FEATURES

O-ring seal
POTENTIAL APPLICATIONS
Steering position
Tachometers/counters
Encoders
Speed and direction of gears and shafts in transmissions,
hydraulic motors, pumps, and gear boxes
most environmental conditions as well as EMI (electromagentic
interference) hardened. Multiple connection options, including
wire harness and integral connector versions using AMP super
seal or AMP Jr. Timer connectors, are available. Package
design includes an o-ring seal for pressure applications and a
fixed mounting flange.
Unique patented (pending) IC (integrated circuit) packaging
provides output phase shift tolerancing with enhanced
accuracy.
