Mold cavity design reduces resin flow resistance in side channels to fill them before upper regions, integrating electronic units with housings.
A relative angle detection device calculates torque using sine and cosine signals from multipolar ring magnets.
An integrated temperature sensor compensates for thermal drift in magnetostrictive torque measurements, eliminating the need for shaft pre-magnetization.
An asymmetric convex part on the holding ring prevents incorrect insertion of the torque detection device, avoiding electrical signal phase reversal.
