Comapct, rugged dual-channel magnetostrictive encoder

MTS Sensors is announcing the Temposonics A-Series "Duo" linear encoder. This compact, rugged device features two output channels: an incremental interface and a synchronous serial interface (SSI). Targeted at manufacturers under pressure to find more robust options for position and velocity control in electric and linear motor designs, this new device enables implementation of measurement systems requiring absolute position feedback while also maintaining an incremental encoder signal for the motor position. The ability to capture absolute position data means that recalibration is no longer necessary.

The incremental interface (either TTL quadrature or 1 Vpp sin/cos) 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. A measurement resolution of 1 μm is delivered. MTS Sensors' innovative Temposonics magnetostrictive sensing technology provides a very accurate non-contact method by which to measure position in applications with the most exacting of demands. When compared with traditional products used in these application scenarios, such as optical encoders, A-Series devices offer several significant advantages, including improved shock performance (up to 100g) and vibration resistance (up to 15g over frequencies from 20Hz to 2000Hz). These devices can deal with relative humidity levels of up to 90 per cent and an operating temperature range of -40degC to +85degC (-40degF to +185degF) is supported. They also offer IP67-level protection to liquid ingress when appropriate connectors are fitted.

Dr Olaf Kissing, Product Manager for Industrial Sensors at MTS Sensors, states: "This new product series allows use of advanced magnetostrictive linear positioning in applications where this wasn't previously possible, so that greater accuracy and improve reliability can be realized. These devices go beyond what can be achieved by conventional linear encoder options, with extremely low failure rates resulting, as well considerable reductions in implementation and maintenance costs. The Temposonics technology at the heart of the A-Series does not require air plumbing, covers or moving cables, making these encoders easier to install. Furthermore, there are there are no requirements for periodic cleaning or calibration. This means manufacturers can reduce their operational expenses significantly by employing such an approach."
