APPLICATION • COMPONENT DEVELOPMENTS Honeywell is rounding out its SMART position sensor portfolio with the new Rotary Configuration that provides 360° non-contact angular position sensing. With this product, Honeywell offers a SMART Position Sensor that encompasses the most basic geometric configurations: lines, angles and circles. The sensor is durable, accurate and cost-effective, enabling design engineers to replace an optical encoder, or to utilize a sensor instead of a resolver, which can be expensive and difficult to integrate into a system. The SMART Position Sensor utilizes non-contact magnetoresistive (MR) technology to determine the object’s position, which allows it to accurately sense position in dirty and harsh environments, replacing optical encoders that utilize light to determine position, to obtain an accurate measurement. Resolvers are typically hand-wired devices with high accuracy and durability for use in incredibly precise, non-serviceable aerospace applications. Honeywell developed the sensor to offer the high level of accuracy needed for the specific transportation and industrial applications in which it is designed to operate, measuring values down to 0.01º. Potential transportation applications include steering angle, articulation angle and boom arm detection, while industrial customers could use it in solar panels or wind turbines. The SMART Position Sensor’s automotive-grade potting makes it more resistant to vibration, shock and extreme temperatures, improving reliability and allowing for use in a wide variety of tough applications. Repeatable output that occurs within a 3.0 mm ±2.0 mm (0.118 in ±0.079 in) air gap between the sensor and magnet collar expand application opportunities. The sensor also provides minimal signal error with up to 2.50 mm (0.10 in) of radial error, simplifying design-in.

OEMs and manufacturers are finding Crouzet’s Linear Motor series a solution in helping reach that goal. The linear motor offered by Crouzet, a brand of Custom Sensors & Technologies (CST), provides varying gas flow control instead of straight on/off control. Today’s typical gas furnace has a shutoff valve whereby gas output is either fully on or fully off, no matter the usage required. By incorporating the Crouzet modulating device into furnaces and other types of gas-burning products, gas flow can be controlled and dispensed in varying amounts so that fuel is burned at a slower or faster rate as needed. This results in improved burning efficiency, saving energy and reducing pollution. Typical applications include gas heaters, gas fireplaces, gas boilers and other types of equipment that use gas valve control. The Crouzet motor features accurate regulation of the linear stepper motor that allows replacement of two electromagnets per channel, and requires only one channel A•CD ContinueD on pAge 20 www.MagneticsMagazine.com Modulating Linear Motor with Integrated Safety Helps Meet Green Initiative to Save Natural Resources and Reduce Costs Now available worldwide!
