Magnetostrictive sensor improves reliability in linear motors

MTS Sensors has released the Temposonics A-Series 'Duo' linear encoder. This compact, rugged device features two output channels - an incremental interface and a synchronous serial interface (SSI).

The incremental interface incorporated into each A-Series device is able to provide position data and velocity feedback for the motor, whereas the accompanying SSI output provides the absolute linear position of the sensor. The device is said to deliver a measurement resolution of 1µm.

MTS's Temposonics magnetostrictive sensing technology provides an accurate non-contact method to measure position in applications with exacting demands. The A-Series devices feature shock performance up to 100g and vibration resistance up to 15g over frequencies from 20Hz to 2000Hz. These devices are also said to operate in humidity levels of up to 90% with an operating temperature range of -40 to 85°C. They also offer IP67 level protection to liquid ingress when appropriate connectors are fitted.
