Product Introduction
QM PKB.2P.312.BLLW is a 2P‑format 12‑pin push‑pull self‑locking circular connector designed for high‑reliability interconnection in medical and precision equipment. It uses white PSU housing material with excellent heat resistance and chemical stability, matching 0.7mm tin‑bronze gold‑plated contacts to ensure low contact resistance and stable long‑term signal transmission. The connector is equipped with standard collet cable clamping structure, supporting multiple cable diameter ranges to protect cables from bending damage. It adopts push‑pull self‑latching mechanism for fast plugging and reliable locking, avoiding accidental disconnection during operation. Multiple key coding options including B, C, D, H, J effectively prevent mismating and ensure safe connection. Key electrical parameters: rated current 7.0A, withstand voltage 1250V AC, insulation resistance ≥5000MΩ, contact resistance ≤12.5mΩ. It meets material compliance and medical safety requirements, and is widely used in minimally invasive surgery, surgical energy equipment, endoscopy, monitoring diagnosis, in vitro diagnostic and industrial precision instruments.
Product Advantage
Stable Signal Transmission
Gold‑plated tin‑bronze contacts deliver low contact resistance and low signal attenuation. It maintains stable transmission for weak signals and medium power with strong anti‑interference capability.
Efficient Push‑Pull Self‑Locking
Push to lock, pull to release. Fast and smooth mating with reliable locking, suitable for frequent connection in handheld devices and cable assemblies.
Medical‑Grade Housing Material
White PSU housing provides good biocompatibility, high temperature resistance and disinfectant corrosion resistance, suitable for repeated medical applications.
Multi‑Key Anti‑Misinsertion
Multiple key codes and angle designs prevent wrong mating, avoid short circuit or equipment damage, and improve system safety.
Wide Cable Compatibility
Collet clamping structure matches multiple cable diameters, with stable strain relief and enhanced durability in dynamic use.
Long Service Life
Stable electrical performance after long‑term mating cycles, with high consistency for mass production and long‑term equipment use.
