4. Shielding Underestimation: High-noise environments using non-SH connectors → Opt for SH suffix (e.g., 1424668/1515170) to suppress EMI.
5. Solenoid Control Using Standard Connectors: 12-channel solenoid valves using 4-core connectors → Select 12SOL series (1404411/1404420) for dedicated control.
6. Grounding Overlooking: Industrial systems without PE connectors → Include 2/3PE variants (1419642/1408987) for electrical safety compliance.
7. Regional Certification Neglect: Regulatory-required projects using non-VA variants → Choose VA suffix (e.g., 1440782/1553268) for voltage compliance.
8. Installation Tool Requirement: Tool-free assembly needs using non-CCL connectors → Select CCL suffix (1424700) for click-lock installation.
