Honeywell 2SS52M Magnetoresistive Sensor ICs

Honeywell 2SS52M Magnetoresistive Sensor ICs are solid-state, omnipolar devices that detect low magnetic fields using an integrated magnetoresistive bridge and provide a digital output. These sensor ICs detect either the North or South magnetic pole, simplifying installation and improving resolution when used with rotating magnets. The 2SS52M series sensors operate within a temperature range from -40°C to +150°C and support a maximum supply voltage of 30Vdc. These RoHS compliant sensors are available in five package styles and support a maximum output current of 30mA. Typical applications include motor RPM sensing, liquid level detection, and position sensing.
