OMRON provides two types of couplings for different application conditions: Resin and metal. Select the best type for the application.
OMRON provides two types of couplings for different application conditions: Resin and metal. Select the best type for the application.
As a general rule, use metal couplings for high resolution and resin couplings for low resolution. (As a rough guide, a high resolution is one that exceeds 3,600 ppr.)
Even for applications requiring relatively low resolution, a metal coupling will provide more reliability in applications involving rapid acceleration/deceleration or for Encoders with high starting torque.
