Coaxial switch ports are critical for maintaining signal integrity, but improper handling can lead to connector wear, thread stripping, or internal misalignment. Follow these best practices to avoid damage:

1. Proper Connection & Disconnection

• Use Torque Wrenches: Apply manufacturer-specified torque (e.g., 8–12 in-lbs for SMA, 15–20 in-lbs for N-type) to avoid under/over-tightening.

• Straight Alignment: Ensure connectors are perfectly aligned before threading to prevent cross-threading.

• No Side Loads: Avoid bending cables connected to ports, which can deform the center pin.

2. Environmental Protection

• Dust Caps: Always install protective caps on unused ports to prevent contamination.

• Avoid Moisture: Use switches rated for IP67 or higher in humid environments.

• Temperature Limits: Stay within the operating range (typically –40°C to +85°C) to prevent material stress.

3. Handling & Maintenance

• No Forced Insertions: If a connector doesn’t thread smoothly, inspect for debris or damage.

• Regular Cleaning: Use isopropyl alcohol and lint-free swabs to remove oxidation or dust.

• Inspect Connectors: Check for bent pins, scratches, or plating wear before use.

4. Electrical Considerations

• Power Limits: Do not exceed the switch’s max RF power rating (e.g., 1–5W average) to avoid arcing.

• ESD Protection: Ground yourself when handling to prevent electrostatic discharge damage.

5. Mechanical Stress Prevention

• Secure Mounting: Fix switches firmly to avoid vibration-induced wear.

• Cable Strain Relief: Use cable clamps to reduce stress on ports.

6. Common Mistakes to Avoid

• Overtightening: This can crack connector bodies or compress dielectrics.

• Using Mismatched Adapters: Avoid mixing incompatible connector types (e.g., SMA to BNC without proper adapters).
