Description
Differential Magnetoresistive Sensor MRVS-011
The differential magnetoresistive sensor MRVS-011 consists of two series coupled magneto resistors ( InSb/NiSb semiconductor resistors whose value can be magnetically controlled), which are mounted onto an insulated ferrite substrate. The sensor is encapsulated in a metallic or plastic package and has 3 connection terminals. The basic resistance of the total system is 2 x 300Ω. A permanent magnet, which supplies a biasing magnetic field, is fixed on the base of the sensor.
· Sensing over wide rotation speed range
· Robust metallic or plastic housing
· Signal amplitude is speed independent
· Biasing magnet built in
· Best suited for harsh environments
· Speed detection
· Position detection
· Rotation detection
· Angle encoder
· Linear position sensing
