CMA Standoff

Reinforced receptacle with screw-fixing for secure and reliable PCB mounting

Reinforced receptacle for secure PCB mounting

• STANDOFF RECEPTACLE
• HIGH CONTACT DENSITY
• SECURE FIXATION
• EMI-RFI PROTECTION

The CMA Standoff is a reinforced PCB-mount receptacle derived from the CMA series. Its standoff design — with integrated screw fixing for secure fixation — ensures a stable, vibration-resistant installation on rugged equipment panels. Stainless steel, IP68, and EMI/RFI shielded, it is designed for high-density PCB integration in demanding environments.

Secure PCB fixation and high contact density for panel-mounted applications

Where standard receptacles can loosen under vibration or mechanical stress, the CMA Standoff provides reinforced PCB fixation through its screw fixing secured standoff mount. This makes it particularly suited to rugged equipment where connection integrity under continuous vibration is a requirement. Available with 14 or 22 contacts in PCB pin termination, it supports high-density signal integration directly onto PCB.
