SNDH Series

Quadrature General Industrial

Speed and Direction Sensors

DESCRIPTION

The SNDH 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.

This product is designed for applications where extremely high resolution is required at wide frequency ranges, 0 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

•

Hall-effect magnetic sensing technology

• Dual differential Hall provides enhanced target resolution

• Advanced performance dynamic offset self calibration

•

Air gap up to 2 mm [0.08 in]

• Near zero speed

• Automotive under-the-hood packaging integrity

•

EMI hardened

• High frequency switching capability (up to 15 kHz)

• -40 º C to 150 º C [-40 °F to 302 °F] continuous operating temperature

• Multiple connector options

• Short circuit protection

•

Reverse voltage protection

• Open collector output

• Low jitter output

•

O-ring seal

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, 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.

POTENTIAL APPLICATIONS

• Steering position

• Tachometers/counters

•

Encoders

• Speed and direction of gears and shafts in transmissions, hydraulic motors, pumps, and gear boxes
