Advantages include high sensitivity so lower cost magnets such as alnico or ceramic can be used, insensitivity to shock and vibration, and ability to withstand large variations in the gap between the sensor and the magnet. The HMR4001 is manufactured with Honeywell's HMC1512 Magnetic Displacement Sensor IC, which provides better performance than Hall Effect devices and only needs a magnetic field source greater than 80 gauss. Dual frequency PWM and analog outputs plus a sleep mode function are included on board APPLICATIONS Block Diagram · Linear Displacement · Shaft Position · Angular Displacement · Proximity Detection Web Site: Email: www.magneticsensors.com ssec.customer.service@honeywell.com 2001 HMR4001 Published Jun 2001 Page 1 Honeywell Solid State Electronics Center 12001 State Highway 55 Plymouth, Minnesota 55441-4799 1-800-323-8295 HMR4001 SENSOR PRODUCTS Advance Information SPECIFICATIONS Characteristics Conditions HMR4001 Min Typ Max Units Linear Position Range > 80 gauss at sensor 10 mm Accuracy > 80 gauss at sensor 0.2 mm Repeatability > 80 gauss at sensor 0.05 mm Range > 80 gauss at sensor 90 deg Accuracy > 80 gauss at sensor 0.1 deg Repeatability > 80 gauss at sensor 0.07 deg Angular Position Magnetic Field Strength Repeatability
