S Series Metal Push Pull Connector

QM S Series Metal Push Pull Connectors are compact, high-density circular connectors designed for highly integrated equipment and high-interference operating environments. With a miniaturized structure and reliable push-pull locking design, the S series helps equipment designers arrange more signal connections within limited installation space while maintaining stable transmission performance.

A key feature of the S series is its unique half-moon hermaphroditic contact design. This structure allows the same type of connectors to mate with each other without distinguishing male and female connector sides, simplifying connector selection, inventory management, field wiring and on-site maintenance. It also helps reduce misinsertion risk and maintain stable contact performance under vibration.

Equipped with 360° full shielding, QM S series connectors provide strong EMC protection for analog and digital signal transmission in complex electromagnetic environments. They are suitable for test and measurement equipment, broadcast audio and video systems, industrial automation, scientific research instruments, aerospace, automotive electronics and semiconductor manufacturing equipment requiring compact layout and reliable signal integrity.

Key Features

  • High-density compact design
    Supports efficient signal connection in limited installation space, making it suitable for highly integrated equipment.

  • Designed for high-interference environments
    Helps maintain stable signal performance in complex electromagnetic conditions.

  • Half-moon hermaphroditic contact design
    Allows the same connector type to mate with itself without distinguishing male and female sides.

FAQ

What is an S series metal push pull connector?

An S series metal push pull connector is a compact circular connector designed for high-density signal transmission and high-interference environments. It uses a push-pull locking structure and supports stable analog and digital signal transmission.

What is a hermaphroditic contact design?

A hermaphroditic contact design allows the same connector type to mate with another connector of the same type, without distinguishing male and female sides. This can simplify inventory, wiring and field maintenance.

What is special about the half-moon contact design?

The half-moon contact design supports stable mating, helps prevent misinsertion and maintains reliable contact under vibration. It is useful in compact, high-density and frequently wired equipment systems.

How is the S series different from the B series?

The B series is a general-purpose compact metal push pull connector for multi-channel signal transmission. The S series is more specialized for high-density, high-interference environments, with hermaphroditic contact design and 360° full EMC shielding.

Are S series connectors suitable for analog and digital signals?

Yes. With 360° full shielding and stable contact design, S series connectors are suitable for both analog and digital signal transmission in complex electromagnetic environments.

Can S series connectors simplify field wiring?

Yes. The genderless mating structure helps simplify connector selection and on-site wiring because the same connector type can mate with itself, reducing male/female part matching complexity.
