4P Plastic Push Pull Connector

QM 4P Plastic Push Pull Connectors are ultra-high-density self-locking circular connectors designed for medical electrophysiology, medical imaging equipment, multi-parameter monitoring systems, industrial automation and other complex precision applications. The 4P series is suitable for equipment that requires centralized transmission of multiple weak signals within a limited installation space.

Compared with lower-density plastic push pull connector series, the 4P series provides greater signal integration capability for advanced medical and precision systems. Its standardized interface design supports direct docking with common interface structures and can be used for replacement or maintenance projects, helping reduce equipment upgrade costs and simplify component sourcing.

With a reliable push-pull self-locking mechanism and anti-misinsertion structure, QM 4P connectors help ensure fast mating, stable connection and safer operation in key equipment. The series performs steadily across a wide temperature range and offers practical protection for medical clean environments, laboratory systems and conventional industrial working conditions.
