2P Series Socket PKB.2P.312.BLLW
QM PKB.2P.312.BLLW is a 2P-size circular female push-pull self-locking connector with 12 contacts. Featuring a white housing, it is well-suited and aesthetically pleasing for medical, semiconductor and other industries, with an ergonomic mating feel. The PSU housing withstands 134°C high-temperature sterilization and corrosion.

Product Description
· Stable & Reliable Signal Transmission
Gold-plated contacts ensure low contact resistance and minimal signal attenuation. It delivers stable performance for both weak signal sensing and medium power transmission, with strong anti-interference ability to maintain data integrity in various working environments.
· Efficient Push-Pull Self-Locking Connection
The push-pull latching system enables fast and secure connection: push to lock, pull to release. It supports smooth blind mating without loosening or accidental disconnection, making it ideal for frequently plugged medical handles, probes and device cables.
· Medical-Grade Material & Sterilization Resistance
Constructed with high-temperature PSU/PPSU material, it can withstand 134°C autoclaving, chemical corrosion and medical disinfectants. Excellent biocompatibility makes it highly suitable for repeated-use medical connectivity applications.
· Anti-Mismating Design
Multiple key coding options effectively prevent wrong insertion and cross-connection. This protective design avoids short circuits or equipment damage caused by misoperation, greatly improving the safety and stability of the entire system.
· Long Service Life & High Consistency
The mechanical lifespan reaches thousands of mating cycles. Electrical performance remains stable after long-term use, ensuring consistent quality in mass production and long-term equipment applications.
