Switchcraft’s Dura-Pull™ series offers up to nine contacts in a durable metal connector only 1/2" in diameter. Dura-Pull connectors are made from nickel-plated brass with a medical technology grade plastic insulator and gold plated contacts. They are sealed to IP68, autoclavable for medical applications, and are rated for at least 5,000 insertion / withdrawal cycles. Although they are less than 1/2" in diameter, they can be ordered with up to nine contacts (two through five #20 contacts or six through nine #26 contacts). Their unique contacts can be either soldered or crimped for maximum flexibility and easy installation. These connectors are made in the USA; factory assembled cables are also available.
