Littelfuse 54100 & 54140 Omnipolar TMR Sensors

Littelfuse 54100 and 54140 Omnipolar TMR Sensors are 3-wire sensors capable of switching up to 5.5V_DC and 3mA output current. These miniature flange-mounting sensors offer excellent thermal stability and operation with north or south poles, and the sensor design allows both screw and adhesive mounting. The 54100 sensors measure 25.5mm x 11mm x 3mm, while the 54140 sensors have dimensions of 23mm x 14mm x 5.9mm. Littelfuse 54100 and 54140 Omnipolar TMR Sensors are suitable for position and limit sensing, RPM measurement, and flow metering.
