Reliable Overmolded Metal Push Pull Connectors
QM provides matching cable plugs, panel receptacles and customized cable assemblies for complete BP and KP connection systems.

Reliable Connections Beyond the Metal Shell
QM overmolded metal push pull connectors combine the mechanical reliability and shielding path of a metal connector with the lightweight protection of a special plastic exterior. The push-pull self-locking design enables fast mating and secure retention, while PPSU material options support non-magnetic, corrosion-resistant and medical-compatible applications.
The BP series supports fixed receptacles, mixed coaxial and signal layouts, and different protection targets according to the selected configuration. The KP series places greater emphasis on IP68 sealing when fully mated, making it suitable for equipment exposed to moisture, cleaning, dust and demanding operating environments.
BP Series Connectors
QM BP series overmolded metal push pull connectors are available with different protection levels from IP50 to IP68, depending on the selected model, mating combination and sealing structure. The series supports 360° EMC shielding, PPSU housings, non-magnetic options and customizable colors.
BP series can also accommodate signal, power and coaxial contact configurations, making it suitable for medical devices, semiconductor equipment, testing instruments and other precision systems requiring compact and stable connections.

Semiconductor test equipment
Precision measurement systems
Mixed coaxial and signal transmission
Multi-interface equipment panels
KP Series Connectors
QM KP series focuses on IP68 waterproof connection solutions. When the matching plug and receptacle are fully mated with the required panel and cable sealing structures, the connection system can protect equipment against water, dust and demanding operating environments.
The series combines reliable push-pull locking, 360° EMC shielding, PPSU housing and strong electrical insulation. Selected configurations can withstand more than 200 high-temperature steam sterilization cycles, supporting reusable medical and harsh-environment equipment.

Advantages of QM Overmolded Metal Connectors
BP and KP series are designed to balance electrical stability, material safety, environmental resistance and practical equipment integration.
360° EMC Shielding
An enclosed full-circumference shielding structure helps reduce external electromagnetic interference and internal signal leakage, supporting stable signal transmission in precision medical, semiconductor and testing equipment.
Flexible BP, Sealed KP
BP solutions support different protection targets according to the selected model, mating pair and sealing design. Selected KP configurations provide IP68 protection when the matching connectors are fully mated.
Medical-Grade PPSU Housing
PPSU housing options provide high-temperature stability, biocompatibility and a clean appearance suited to medical equipment. Non-magnetic configurations, housing colors and positioning-key colors can be customized for project requirements.
High Electrical Insulation
PPSU shells combined with PPS or PPS/PTFE insulation components help maintain electrical isolation and dimensional stability. Rated voltage and insulation performance are confirmed according to the selected contact arrangement and model.
Impact & Corrosion Resistance
The overmolded exterior cushions light impact and protects the internal metal structure from everyday surface wear. Selected models also withstand vibration, shock and 96-hour salt-spray testing for humid or corrosive environments.
200+ Sterilization Cycles
Selected BP and KP medical configurations can withstand more than 200 cycles of 134°C steam sterilization. The PPSU structure maintains dimensional and electrical stability during repeated cleaning and disinfection.


Applications for QM Overmolded Connectors
Medical & Surgical Equipment
Semiconductor Test Equipment
Underwater & Harsh Systems
QM Custom Connector & Cable Service
Contact Layout Customization
Configure 2 to 32 contacts according to signal, power and control requirements. BP solutions can also integrate coaxial and standard signal contacts within one compact connector interface.
Material & Color Customization
Select housing materials according to sterilization, biocompatibility, corrosion, temperature and non-magnetic requirements. Housing color, positioning-key color and identification details can also be adapted to the equipment design.
Waterproof Assembly Design
We evaluate plug, receptacle, panel seal, cable exit and tail sealing as one connection system. This helps achieve the required protection level rather than evaluating a connector component separately.
Keying & Panel Integration
Different positioning keys help prevent incorrect mating in multi-interface equipment. We can also adapt installation structure, panel mounting, cable direction and matching plug or receptacle configurations.
