Rated to IP66 and IP67, the Multi-Drop Sealed Connector and Cable System from Molex uses cable-pierce technology to offer a rugged, free-form, pluggable connector string that can be customized to meet any requirements for internal and external data/signal and power applications
The system has been designed to offer the customer a sealed, modular, cable connector system for use in the transfer of both power and data/signal in a multi-drop configuration. The string layout and pluggable connector interface can be fully customized giving customers greater flexibility when designing their applications. Custom strings can be pre-assembled or terminated on site based on the customer's handling and field installation capabilities. The system is suitable for many lighting and power applications, security systems and sensors in environments such as office buildings, road infrastructure, car parks, public transport, city centers and other public places.

Comprised of multiple connector modules attached to a specially designed cable, each connector module in the system has 3 sections; top and base housings which are terminated to the cable and a custom pluggable connector with an interfacial seal. When the two housings are terminated, cable-pierce technology uses pointed pins to pierce through the gel mat and cable insulation to make contact with the cable cores. Cable-pierce technology is a single termination process suitable for applications up to approximately 3A. Connections can be made on stranded cores on wire of 1.50mm (16 AWG) or greater. The higher the number of strands the better the electrical connection that can be achieved with this termination method. Cable alignment to pin is also a major consideration during termination.
The top and base housings are held in place by permanent retention studs, providing constant compression of the connector on the cable. After termination the pierced gel mats are loaded under positive pressure. This compression volumetrically fills the terminating chamber, creating a gel sandwich around the profile of the cables and pins to form a water-tight seal. In water at a depth of 1 meter, tests reveal full waterproofing and no short-circuiting of the electrical connections. This test has been conducted throughout the operating temperature range of the system, from -30 to +80°C. When fully assembled, cable-pierce termination technology, permanent retention studs, gel mats and the interfacial seal ensure a sealed connector rated at IP66 and IP67.
Key applications include: interior and exterior cable lighting systems; occupancy sensors in multi-level car parks; smoke alarm systems; speaker/sound systems; power connections; and external cable connections requiring a sealed connector system.
