Issue 49/2015 - Polyamide 12 improves steering angle sensor gear accuracy

Recently, Valeo Schalter und Sensoren GmbH, headquartered in Bietigheim-Bissingen, Germany, selected VESTAMID?L1930 polyamide 12 from Evonik as the gear transmission mechanism material
for steering angle sensors.

The materials used for gear drives must meet stringent requirements to ensure high accuracy and durability of steering angle sensors and to maintain the necessary angular accuracy
.
VESTAMID?L1930 products have exactly these characteristics: as a polyamide 12, it can be stable in a wide temperature range (-40~125 °C), and its physical properties only change slightly with different ambient humidity; The molded parts undergo almost no dimensional changes
.
The material has very high impact resistance and notch (notch) impact strength even below freezing, and has good resistance to grease, fuel, hydraulic oil and salt solutions, making it ideal for
automotive applications.
Its excellent wear resistance and low sliding friction coefficient are important for the gears of steering angle sensors, in addition to noise and vibration
damping.

The continuous development of the VESTAMID® series allows it to be used in a wide variety of applications, from wiring systems (piping systems) to cable sheaths to extremely small injection molded parts
