1 Magnetic sensors for rotary applications MDFK 08, 2 channel features competitively priced angular measurement solution using or magnetic rotor 2 channel version channel A/B 90 shifted 8-/16-fold interpolation description Magnet encoders provide angular information by n-contact tracking of a multi-pole based on a magneto resistive sensor. Depending on the angle between the sensor and the magnetic field, the device generates analog signals containing the angular information. These signals are further fed into an electronics circuit for additional conditioning and processing. The rugged and easy to mount sensor generates 4'096 steps when used in conjunction with a of 64 poles. Angular resolution of the device can be partly determined by selecting appropriate s. The protected sensor contains absolutely moving parts and is t subject to any wear when in operation. Air gap between magnet and sensor can be up to 0,8 mm without sacrificing system accuracy. part numbers 8-fold interpolation 2 channel push-pull MDFK 08G21 2 channel complementary MDFK 08T71 16-fold interpolation 2 channel push-pull MDFK 08G2124/N16 2 channel complementary MDFK 08T75/N16 technical data voltage supply supply current switching current max. switching frequency voltage drop output circuit A/B output signal air gap resolution interpolation 8-fold* max. measuring steps 1'024 steps short-circuit protection reverse polarity protection temperature range housing material max. protection class connection cable PUR 4 x 0,25 mm 2 *lower interpolation rates on request MDFK 08G21 MDFK 08T71 MDFK 08G2124/N16 MDFK 08T75/N16 push-pull push-pull 8-3DC 8-28 VDC 35 ma 55 ma 20 ma 50 ma 160 khz 160 khz 3,2 MHz 3,2 MHz < 4 VDC < 2 VDC (IOUT = 20 ma) (IOUT = 20 ma) push-pull CH A/B max. 0,8 mm 256 ppr TTL () CH A/A/B/B max. 0,8 mm 256 ppr 8-fold* 1'024 steps 6 x 0,14 mm 2 push-pull CH A/B max. 0,6 mm 512 ppr 16-fold* 2'048 steps 4 x 0,25 mm 2 TTL () CH A/A/B/B max. 0,6 mm 512 ppr 16-fold* 2'048 steps 6 x 0,14 mm 2

Depending on the angle between the sensor and the magnetic field, the device generates analog signals containing the angular information. These signals are further fed into an electronics circuit for additional conditioning and processing. The rugged and easy to mount sensor generates 8'196 steps when used in conjunction with a of. The MDFK range of sensors provides a high degree of installation flexibility due to the position of the magneto-resistive pick-up being at the center of the device's face. An important fact when space is at a premium.
