Forest harvesters revolutionized logging. Littelfuse engineers kept pace with off-the-shelf and custom-designed power distribution modules and high-voltage fuses that withstand the harshest environments. We also provide electronics solutions for dc motor and hydraulic pump controllers. These include feeder protection relays, dc–dc converters, and plunger switches for push-button operation.

Electric, diesel, gasoline, or alternatively fueled, each tractor requires advanced electronic components. Littelfuse meets those demands. For example, we offer power distribution modules sealed against dust and water. We also make a starter solenoid relay for smaller engines that often sit idle and a dc vehicle connector just for farm equipment. It has doors to keep debris out of the socket.
