Gearshift Sensor

Introduction

More and more electronic control is being used in automobiles and trucks in "drive by wire" implementations, replacing traditional mechanical systems which are highly susceptible to wear.  For improved functionality and ease of control, the transmission shifter arm movement in certain trucks is monitored using reliable Reed Sensors.

When battery drain is a concern in automobiles, the magnetically actuated Reed Sensor is the perfect solution since they draw no power when the vehicle is off.  The MK16 Reed Sensor, an over-molded hermetically sealed Reed Switch is one of several surface mount sensors which can be used in a gear shifter application...
