Bayonet-style Power Connectors Endure Harsh Environments

ITT Industries, Cannon has introduced the Powerlock connector series for field-installable power distribution systems. Equipped for the most severe operating conditions, the connector range provides a high level of safety and reliability.

The Powerlock connectors use a bayonet mating method and come in four standard formats: panel source, panel drain, line source and line drain. Source connectors are supplied with a male contact that incorporates a rigid finger-proof nose and a slot for the secondary locking pin. Drain connectors include a female contact with a spring-loaded finger-proof nose and an O-ring. Line or panel connectors support cable attachment or panel mounting, respectively.

All of the Powerlock series connectors are rated to 3000 V (max) and are available in 400-A and 660-A versions. Designed to withstand harsh environments, the connectors provide IP67-rated sealing, shock protection to levels specified by IP2X, and operation beyond a -30°C to +125°C temperature range.

The connector range supports contact termination sizes from 25 mm2 to 300 mm2. The line source connectors use either screw or crimp termination for the 400-A and 660-A versions, respectively. The panel drain and line drain connectors use an insulator fitted with a spring-loaded secondary locking pin. Panel receptacles come fully assembled with contacts. An M12 nut and spring washer also are supplied, which fit loosely onto the contact.

Housed in a high-temperature thermoplastic shell, the Powerlock series is rated for flammability to UL94-V0 and available in a range of colors: green, black, red, blue, yellow, brown, gray and white. The price for a mated pair of Powerlock connectors starts at $70. Snaplock connectors start at $55 per mated pair.
