CHICAGO – Littelfuse Inc. in Chicago is introducing the 54100 and 54140 miniature tunnel magneto-resistance (TMR) effect sensors for position and limit sensing; RPM measurement; flow metering; commutation of brushless DC motors; magnetic encoders, and angle sensing.
The key differentiator of the 54100/54140 motion control sensors is their sensitivity and 100x improvement in power efficiency compared to Hall Effect sensors. These sensors offer activation in the x-y plane instead of the traditional z-axis, and operate in temperatures from -40 to 100 degrees Celsius.
The 54100 flange-mount sensor's compact housing dimensions measure 25.5 by 11 by 3 millimeters. Its case allows for screw and adhesive mounting, and offers a 3-wire configuration for power, ground, and output.
This sensor can switch as much as 5.5 volts DC and 3 milliamps power output current, and the sensor leads offer standard lengths of 300 millimeters and 1000 millimeters. The 54140 flat pack sensor measures 23 by 14 by 5.9 millimeters, and provides digital output and a three-wire sensor configuration.
