QLC - Miniature Zero Insertion Force
ITT expands its DL Family of Connectors with the Miniature QLC device to meet size, reliability, and mating requirements for Portable Medical Equipment. Similar to the DL Series connectors, the QLC connector is highly reliable, easily assembled during harnessing and features a high pin count, 260 contacts in PC Board-mount style. The receptacle is available in both standard solder tail and press-fit contacts. The QLC employs rugged nickel-plated aluminum housing and features a minimum rated life of 20,000 mating cycles with no performance loss. The interface of the QLC connector utilizes EMI springs and a shield-locking mechanism to ensure uniform mating pressure around the perimeter of the mated connector, creating an EMI/RFI shield. With the current technology advances requiring smaller connection systems, ITT reduced the size from the current DL by more than 60% with the same number of contacts.
Features
- Over 20K mating cycles
- 260 & 440 pin configuration available
- Fully intermateable design
- Solder to PCB through hole or press-fit factory termination
