Magnetic Switch Sensors feature TMR technology.
Press Release Summary:
December 6, 2012 - Integrating tunneling magnetoresistance sensors and signal processing ASICs within SOT-23 or TO-92 package, Model MMS101H features bipolar operation with digital latching output, while Model MMS201H provides omnipolar operation that can be triggered by south or north pole. Sensitive operate and release points are Â±15 Gauss for MMS101H and Â±10/Â±15 Gauss for MMS201H. Consuming less than 4.5 mA while operating continuously, sensors are intended for battery-powered industrial flowmeters.

MDT to Introduce New TMR Magnetic Switch Sensors at Electronica 2012
Press release date: November 13, 2012
The new additions to MDT’s existing TMR magnetic switch sensor portfolio are the MMS101H bipolar magnetic switch and the MMS201H omnipolar magnetic switch, for use in battery-powered magnetic sensor applications including flow meters and proximity switches. They are designed with sensitive switching points at low field, allowing smaller magnets or larger air-gap. They also feature very-low power consumption in continuous operation, enabling high-speed measurement and extended battery life simultaneously.
TMR technology has been widely used in the magnetic disk-drive industry. It has been proven a high-performance, power-efficient, cost-effective and dependable technology over the last decade. MDT is the first volume supplier that introduces advantages of TMR technology to the commercial magnetic sensor market in multiple product series, including TMR magnetic switch sensors, TMR magnetic field sensors, TMR magnetic angle sensors, and TMR gear tooth sensors.
The MMS101H and MMS201H magnetic switches consume very low supply current below 4.5 microamperes while operating continuously. Unlike other magnetic switch products that must employ power cycling or sleeping modes to reduce power, MDT’s magnetic switch sensors exhibit very-low power consumption during high-speed continuous operation.
- Bipolar operation with digital latching output (MMS101H)
- Omnipolar operation that can be triggered by either south or north pole (MMS201H)
- Sensitive operate and release points at +/-15 Gauss (MMS101H), and +/-10, +/-15 Gauss (MMS201H)
- High-speed magnetic field measurement at 1kHz frequency response
