B Series Metal Push Pull Connector

QM B Series Metal Push Pull Connectors are compact, high-reliability self-locking circular connectors designed for multi-channel signal transmission in medical equipment, industrial systems, test and measurement instruments, broadcast audiovisual equipment, rail transit and aerospace applications.

As one of the most widely used metal push pull connector series, the B series provides a balanced solution between compact structure, high-density contact layout, shielding performance and long-term connection stability. Its mature push-pull self-locking mechanism supports fast mating and secure locking, helping prevent accidental disconnection caused by vibration, movement or frequent operation.

QM B series connectors are designed to be compatible with mainstream international push pull connector interfaces, making them suitable for replacement, maintenance, equipment upgrade and cost-optimized sourcing projects. With standardized anti-mismatching coding, flexible termination methods and stable electrical performance across demanding working conditions, the B series provides a practical and reliable interconnection solution for professional equipment manufacturers.

Key Features

  • Classic B series metal connector platform
    Suitable for a wide range of professional equipment requiring compact size, stable locking and reliable signal transmission.

  • Compact structure with high-density transmission
    Supports multi-channel connection needs while helping reduce interface size and save installation space.

  • Push-pull self-locking mechanism
    Enables quick plug-and-play operation and secure locking, reducing the risk of accidental disconnection during vibration or movement.

  • Excellent EMC shielding performance
    Helps reduce electromagnetic interference and supports stable signal transmission in complex electrical environments.

  • Stable performance under wide temperature conditions
    Suitable for medical, industrial, transportation, test and aerospace equipment operating in variable environments.

  • Standardized anti-mismatching coding
    Helps ensure accurate mating and prevents incorrect connection when multiple connectors are used on the same device.

  • Multiple termination methods
    Provides flexible assembly options for different cable, PCB, panel and equipment design requirements.

  • Compatible with mainstream standard interfaces
    Can support direct replacement and simplified equipment upgrading without major design changes.

  • Reliable long-term durability
    Manufactured under strict quality control to support stable use in high-demand professional applications.

  • Suitable for multi-channel signal systems
    Ideal for equipment requiring several signal lines, control channels or sensor connections in one compact interface.

Applications

QM B Series Metal Push Pull Connectors are suitable for professional devices that require compact metal construction, secure locking, shielding performance and multi-channel signal transmission.

Typical applications include:

  • High-end medical devices

  • Precision testing instruments

  • Multi-channel measurement systems

  • Industrial robots

  • Industrial automation equipment

  • Broadcast audiovisual systems

  • Professional camera and video equipment

  • Rail transit systems

  • Aerospace equipment

  • Sensor and control systems

  • Laboratory instruments

  • Special equipment requiring stable signal transmission

Compared with more specialized waterproof or harsh-environment metal series, the B series is better suited as a general-purpose high-reliability metal push pull connector for compact, shielded and multi-channel applications.
