Smiths Digital Speed Sensor

Part #
In Stock In Stock

Designed for heritage cars, Smiths Classic digital speedometers are the perfect way to bring modern technology into your classic. These digital gauges measure either 100 mm (4 in) or 80 mm (3.15") in diameter, and feature a polished chrome bezel with black gauge face and white lettering. The gauge shows a range of 0-140 mph or 0-240 kph with digital odometer/trip readout. With an on-board "drive-to-set" programming, you can fit the speedo, set it to DTS mode, drive a mile/kilometer and the speedo calibrates itself. Complete instructions included.

If your car does not have an electronic speedo output, our speedo sensor kit, part # 440-606, is the right product for you. Fitting both MPH and KPH gauges, it senses a magnetic object, such as a bolt head or a nut, moving past the end of the sensor, creating a 'pulse' which is sent to the gauge and then translated. Easy to set up, it will work with bolt heads from the prop shaft or differential.
