Industrial 9120-R4-M Master R4 Module 4 Amps 250 VAC

The ATI 9120-R4-M Master R4 electrical module is a 4 Amp, 250 VAC master-side interface for ATI Tool Changer systems. It uses a 4-pin Eurofast connector on the master side, housed in aluminum with precious metal–plated pins and a nitrile seal for environmental protection. Weighing about 0.45 lb (0.20 kg), it operates from -20 °F to 150 °F (-28.9 °C to 65.6 °C) and provides moisture and dust sealing when mated, with a potted variant available for use in fluid-prone environments. As the Master component in the R4 family, it supplies the electrical interface required to power and monitor tool-changer operations during automated exchanges, compatible with ATI R4 Tool modules and related adapters.
