Cost-effective quadrature speed and direction sensor

TTI Europe now stocks the Honeywell SNG-Q Series quadrature speed and direction sensor. Offering four-wire quadrature sensing it is the first release of the company's new speed sensor platform. The sensor design and manufacturing use a platform-based approach that enables cost-competitiveness and mechanical and electrical configurability. The SNG-Q Series 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 degree phase shifted from each other. With the quadrature output, target direction is determined by output lead/lag phase shifting. The sensor 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, says the company.
