RR123-1H02-612 TMR Digital Push-Pull Magnetic Sensor-Switch

The RedRock® RR123-1H02-612 is unique in ability as a magnetic sensor/switch to enable a magnetically activated power turn function for power sensitive, battery operated devices by offering extremely low power consumption, an output latching  function and small size.   In addition the RR123-1H02-612 can be used in proximity sensing functions such as open/close detection or tamper detection.

The RedRock® RR123-1H02-612 is a digital magnetic sensor-switch ideal for use in small battery-powered applications such as portable medical devices. It is based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration.

The RR123-1H02-612 features an operate sensitivity of 7G (0.7mT), with an omnipolar magnetic field response. It offers a voltage range from 1.0V up to 3.6V, ideal for applications that use single cell 1.5V batteries. It has the lowest average current drain (20nA) for an active magnetic sensor, operating under 2Hz and with a temperature range from -40°C up to +85°C. This sensor/switch can be used to efficiently source up to 20mA of current to an application circuit. It also has a Latch Control Pin (LCP), which gives the option to keep the output in a given state regardless of any changes in magnetic field.   A coupon board, designed to showcase this sensor’s operation & capabilities is also available.  ( Click here for more information.)
