Differential Magnetoresistive Sensor CY-DMR-03A, Power Supply: 5 V DC, Output: Single output, Alternative for: FR05CM21AR(MuRata)

The differential magnetoresistive sensor CY-DMR-03 consists of two series coupled magneto resistors (D-type 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 package and has 3 connection terminals. The basic resistance of the total system is 2 x 550Ω. A permanent magnet, which supplies a biasing magnetic field, is fixed on the base of the sensor.

The CY-DMR-03 may be considered as a possible replacement or cross-reference type for the sensor FR05CM21AR depending on the specific application. Its electrical and mechanical characteristics are comparable; however, the circuitry principle may differ. The listed cross-reference types are provided for identification and comparison purposes only. Please verify suitability and compatibility using the technical specifications.
