QLC ZIF Connector

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 harness and mating, and features a high pin count up to 260 contacts in PC board-mount style.

The QLC connector employs rugged nickel-plated aluminum housings and features a minimum rated life of 20,000 complete 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 technology advances for small portable imaging equipment, the demand for a smaller, higher pin count, shielded, reliable connector proves essential. Consequently, ITT reduced the spacing from the standard DL to 0.8 mm, thus reducing the overall size by more than 60% with the same number of contacts. 

The high pin count allows the engineer to utilize various grounding schemes to maintain signal integrity. 

The reduction in size, coupled with the superior shield design of the QLC, creates a sound interconnect choice for today’s portable market.
