AI- Tek Passive Speed Sensor Series 70082 – Side Look Sensor

AI- Tek Passive Speed Sensor Series 70082 – Side Look Sensor has been developed by AI-Tek Instruments for Allison automatic transmissions for trucks ranging from light-duty vans to over-the-road tractors.

It mounts directly on the transmission and employs a unique magnet configuration that induces a magnetic field on the side of the sensor in the path of the rotating transmission gear. This system with its fewer mounting parts improves reliability, reduces weight, and conserves space over the earlier designs.

The Passive Speed Sensors Series 70082 – Side Look Sensor is manufactured in the United States. AI-Tek Instruments Distributors stock the SLS for off-the-shelf maintenance, repair, and overhaul (MRO) requirements.

AI-Tek Instruments (formerly Airpax) manufactures hundreds of different designs of magnetic speed sensors and has been supplying these sensors to the industrial, machine tool, petrochemical, and aerospace industries for over sixty years.
