44 Series™ Thermoplastic Circular Connectors

Amphenol Sine Systems 44 Series™ Thermoplastic Rubber Circular Connectors are extremely durable and reliable connectors that resist harsh environmental factors like water, fuel, lubricants, ozone, and road salt. The connectors' crimp-and-insert method reduces installation time and expenses and is vibration-resistant. Amphenol Sine Systems 44 Series Thermoplastic Rubber Circular Connectors feature one to six position variations and a polarized design for quick, error-free, blind connections. Designed for 14AWG to 18AWG wires, the connectors handle various power requirements and offer protection against mis-mating. All 44 Series connectors are IP65/67 rated, RoHS compliant, and ideal for indoor and outdoor rugged applications.
