Magnet Wire for EV/HEV Inverter-Fed Motor

“Magnet wire is used for interchanging electrical energy with magnetic energy”. Magnet wires are broadly divided into enamelled wire (coating insulation), covered conductor wire (fiber/film insulation), and combinations thereof.

We manufacture highly reliable rectangular magnet wire with superior workability and an ultrathin high aspect ratio rectangular wire with superior high-frequency properties as reactor coil use.

Harness for Electric Parking Brakes

We developed harnesses for use in electric parking brakes that excel in flexural resistance and durability. This helps conserve space inside the cabin and elevates vehicle safety and convenience. Our EPB harness are highly durable and maintain a standard level of undamaged electrical properties even after being subjected to more than five million oscillations.

Active ABS Wheel-Speed Sensors

Proterial is a specialist in manufacturing wheel-speed sensors with semiconductor sensing elements to respond to the advances in ABS. The sensors provide stable output throughout, from low to high speed. Another product type that can sense reverse rotation is also available upon request. Our salient features include use of Hall IC to ensure stable output signals even at low vehicle speed with compact & lightweight design.

High Capacity Power Cable Harnesses

Harnesses connect the battery, inverter and motor in hybrid vehicles. Our products have superior heat resistance, oil resistance and flexibility. They are extremely reliable in high-voltage and large-current areas.
