1: Typical, varies by application – contact your sales engineer for application specific rating.
2: The P and S electrical interface option (Molex Mini-Fit Jr. connector) limits the continuous current capacity to
10 amps RMS, which in turn, limits continuous torque capacity.
For more continuous torque use the C or E electrical interface option (Souriau Trim-Trio connectors).
