Push-Pull Self-Locking Connectors
WLconnectivity push-pull self-locking connectors are compact circular connectors designed for fast, secure signal connections in space-constrained equipment. Their self-locking and keyed design helps prevent mismating and accidental disconnection while providing reliable resistance to vibration and shock. Ideal for audio equipment, instrumentation, industrial control, medical devices, and aerospace applications.
B Series
The B Series push-pull self-locking connectors feature a fast and reliable mating mechanism. Simply push to connect and lock automatically, then pull the outer sleeve to release. Their secure connection and convenient operation make them ideal for applications requiring frequent mating, high-density installation, and reliable signal transmission.
The series supports solder, crimp, and PCB terminations, with straight and 90° angled configurations available to accommodate different installation spaces and cable-routing requirements. Contact configurations ranging from 2 to 32 contacts support power, signal, and multi-circuit connections while saving valuable equipment space.
The metal housing and 360° shielding design provide excellent protection against electromagnetic interference. Multiple keying options help prevent mismating between similar connectors. The G key is the standard configuration for accurate connector alignment and mating.
K Series
The K Series push-pull self-locking connectors feature a secure and reliable locking mechanism designed for extremely harsh operating environments. Their rugged metal housing provides excellent mechanical protection, while 360° shielding delivers comprehensive EMC protection against electromagnetic interference.
Available with 2 to 32 contacts, the K Series supports solder, crimp, and PCB terminations in both straight and right-angle configurations. Multiple keying options prevent mismating between similar connectors, while the standard G key ensures accurate alignment during connection.
When correctly assembled with a compatible cable, the connector can achieve an IP68 protection rating, providing reliable resistance to water and dust. Its compact, high-density design saves installation space while maintaining dependable power and signal transmission.
F Series
The F Series connectors feature a secure collet-type push-pull self-locking mechanism and an internal semicircular metal keying system. Their rugged metal housing is designed for extremely harsh outdoor environments, providing reliable mechanical protection and dependable connection performance.
The 360° shielding design delivers comprehensive EMC protection against electromagnetic interference, helping maintain stable power and signal transmission. Available with 1 to 40 contacts, the series supports both solder and PCB terminations for flexible equipment integration.
Its internal semicircular keying system ensures accurate alignment and helps prevent incorrect mating. The compact, high-density design also saves valuable installation space, making the F Series suitable for demanding outdoor, industrial, communication, and instrumentation applications.
