Installation Instructions for the
Quadrature Speed and Direction Sensors
SNG-Q Series
General Information
Honeywell's SNG-Q Series Quadrature Speed and Direction
Sensors are designed to provide both speed and direction
information. Speed information is provided from digital square
wave outputs; direction is provided using a quadrature output
with signals 90° phase shifted from each other. With the
quadrature output, target direction is determined by output
lead/lag phase shifting.

Sensing and Internet of Things
The product is designed for applications where enhanced
accuracy is required to detect small target features. This
accuracy is enabled by dual differential Hall-effect sensor IC
technology. The SNG-Q Series is designed for a wide operating
temperature range, robust electrical noise immunity and
industry leading environmental sealing capability.
This product includes an O-ring seal for pressure applications,
and a fixed mounting flange for simple installation using one
fastener.
