The RELIANCE 57C373 is a resolver connector cable assembly designed for the AutoMax servo motion control system. It provides a dedicated, shielded wiring link between resolver feedback devices and servo drive/controller modules (such as 57C422B), ensuring accurate position and speed signal transmission in motion control applications.

RELIANCE is the brand of industrial control and motion products. 57C denotes the AutoMax system I/O and accessory series. 373 identifies a resolver-specific connector cable assembly for servo feedback, differentiating it from general-purpose terminal strips like 57C370.

Constructed with multi-conductor shielded cable for noise suppression. Features keyed proprietary connectors at both ends to prevent miswiring. Operating temperature ranges from 0°C to 60°C. Supports resolver signal levels: excitation voltage 7–14 Vrms, frequency 400 Hz–10 kHz. Conductor gauge and shielding meet industrial EMC requirements for motion control systems.

One end mates with the servo controller/drive’s resolver port; the other end connects directly to the resolver sensor. Fully shielded design reduces electromagnetic interference. No network ports; it is a passive, dedicated feedback cable for resolver signals only.

Transmits resolver excitation signals and differential position/speed feedback signals between the controller and resolver. Ensures precise, noise-immune feedback for closed-loop servo control. Keyed connectors prevent reverse or incorrect connection. Rugged construction supports long-term use in industrial motion environments.

Used in AutoMax servo motion control systems, connecting resolvers to servo drives or motion controllers. Typical applications include CNC machinery, industrial robots, web handling, and high-precision manufacturing lines in metalworking, packaging, and material handling industries.

Power off the system before installation. Align keyed connectors and insert firmly; do not force connections. Route cable away from high-power cables and sharp edges to avoid damage. Keep connectors clean and dry. Periodically inspect cable insulation, shielding, and connectors for wear, looseness, or corrosion. Replace with the same model if damaged to maintain feedback accuracy and system reliability.
