WIELAND ELECTRIC RST20i5 5-Pole Female Connector with Screw Terminals and Strain Relief, IP66/IP68, 20A, 250/400V, Black

Circular female connector from the RST20i5 series, engineered for robust power and signal integrity in demanding industrial environments. The integrated strain relief and screw terminal connections provide a secure, vibration-resistant link for cables with diameters from 6 to 10 mm, while the IP66/IP68 rating ensures reliable operation even under temporary submersion.

Advantages

The connector's silver-plated brass contacts and UL94 V-0 rated polyamide housing combine excellent conductivity with high flame retardancy. Mechanical screw locking prevents accidental disconnection, and the wide operating temperature range from -40 °C to +100 °C makes it suitable for both cold storage and high-temperature machinery. The 5-pole configuration supports three-phase power plus protective earth, with a rated current of 20 A and voltage up to 400 V AC.
