Rotary position sensor
September 21, 2012 | By Alison Dunn
Honeywell is rounding out its SMART position sensor portfolio with the new Rotary Configuration that provides 360 degree non-contact angular position sensing. The SMART Position Sensor uses 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, which use light to determine position, to obtain a highly accurate measurement. Honeywell developed the new 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 0.01 degrees. 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.
