Cable connector protects against water ingress to safeguard equipment

The Techno TH392 waterproof connector with X-Dry technology is now available from Hylec-APL. All cables are hydroscopic to some degree and will therefore absorb moisture that can collect inside the cable sheath, moving along its length and even crossing terminations in the cable. The X-Dry technology blocks moisture transmission across terminals, protecting electrical and electronic equipment, says the company. "The special barrier prevents moisture condensation, which runs through the cable, from entering the connector, protecting the system in critical conditions of use," said Mark Severn, director of sales, Hylec-APL. The connectors have screw or piercing terminals and can accept cables with diameters from 8mm to 12mm; maximum cable cross section is 4mm2 for screw terminals and 0.5 to 1.5mm2 for the piercing clip terminals. Water and dust protection is to IP68 at 3bar pressure from 30 minutes to two hours. Rated current is 17.5A, 450V, and operating temperature from -40C to +125C. The contact screw terminals are brass nickel plated. The standard screws are steel zinc plated and the piercing screws are plated with steel zinc brass. There are three- and four-way versions. The four-way version takes up 400 x 160 x 205mm. The mini connector is suitable for operation in tight spaces. The piercing clip wiring system can be installed quickly and safely. Accessories include grommets, reducers, lock nuts and a special tool that ensures the correct installation of the product to provide maximum protection. They meet EN60529:1991 +A1:2000, EN60998-1:2004, EN60998-2-1: 2004 and EN60998-2-3:2004, says the company.
