The patented limited-detent architecture provides the right mix between a secure connection and straightforward serviceability. It is not a full-lock connector that needs specific equipment to dismantle, it can be disconnected easily by hand and has very good resistance to vibration. And your maintenance staff will enjoy the reduced complexity of debug and repair processes, during field operations.
Precision CNC machining has been used to achieve minimum coaxial misalignment across the 40 GHz bandwidth. 50Ω impedance design ensures great VSWR performance and thereby minimises signal reflection to minimal levels. You may anticipate flawless transmission on the microwave with little distortion for important high frequency applications.
Gold-plated contact surfaces combined with passivated stainless steel housing provide exceptional corrosion resistance. The connector maintains stable electrical and mechanical characteristics throughout temperature extremes and challenging environmental conditions. This durability translates directly to reduced replacement costs and improved system uptime.
Manufactured according to SMP industry specifications, this connector offers full intermateability with compliant interfaces from other manufacturers. You gain valuable system integration flexibility and can confidently incorporate these connectors into existing infrastructure without compatibility concerns.
The well-engineered PCB pad layout and gold-plated soldering surfaces ensure excellent wettability for both manual assembly and automated manufacturing processes. Whether you're using wave soldering or reflow techniques, you'll achieve high production yields and consistent quality. The design supports rapid assembly without compromising connection reliability.
SIPU implements comprehensive quality control procedures to guarantee consistent performance. Each production batch undergoes dielectric withstanding voltage testing using specialized insulation testers to verify 500V capability and insulation resistance compliance.

Plating quality receives particular attention through batch-level inspection. We measure gold plating thickness and verify plating adhesion strength to ensure long-term reliability. Every production run includes RoHS environmental compliance testing, confirming that your supply chain meets international environmental standards.
Our testing protocols focus on parameters directly affecting your application success. While VSWR and insertion loss characteristics are engineered into the structural design, we verify these critical specifications to maintain the performance standards you depend on.

High-density RF module stacking benefits from the blind-mate capability and moderate retention force. You can replace individual boards during maintenance while keeping adjacent modules securely connected during operation.
Compact ruggedized systems demand connectors that withstand severe shock and vibration. The PCB-mount design eliminates cable stress points while the limited-detent mechanism ensures reliable signal paths in airborne and naval platforms.
Semiconductor test systems require frequent, reliable connections at millimeter-wave frequencies. The limited-detent mechanism reduces connector fatigue compared to full-detent alternatives, extending service life in high-cycling test environments where SMP Male Limited Detent PCB Mount Connector excellence matters most.

Q: What distinguishes Limited Detent from Full Detent retention mechanisms?
A: Limited Detent provides lower retention and withdrawal forces, enabling hand disconnection or simple tool use. Full Detent maximizes vibration resistance but typically requires dedicated removal tools for disengagement.
Q: Does this connector support blind-mating applications?
A: Yes, the design specifically accommodates blind-mate scenarios common in modular backplane architectures where visual alignment is impossible during installation.
Q: What lifecycle can I expect?
A: The connector is rated for minimum 500 mating cycles when alignment remains within specified radial and axial tolerance limits.
Q: Is the connector compatible with lead-free reflow soldering?
A: Absolutely. The PTFE insulator withstands standard lead-free reflow profiles reaching approximately 260°C without performance degradation.
Q: How does axial misalignment impact electrical performance?
A: While the connector tolerates some axial gap variation, increased air space between male and female reference planes typically results in elevated VSWR and phase instability. Maintaining specified alignment tolerances preserves optimal performance.
