These designations refer to the same connector family — PLS20 (plug), WS20 (socket), TP20 (panel mount) — covering the complete connector set for a given application. The metal shell (zinc alloy, nickel-plated) provides superior mechanical robustness and EMI shielding compared to plastic-body GX series connectors, making this series suitable for high-vibration industrial machinery and outdoor equipment where connector body integrity is critical.\u003c\/p\u003e\n\n\u003ch3\u003eSeries Designation Reference\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePLS20:\u003c\/strong\u003e Plug (male housing, cable-mount).

Do not assume interchangeability — verify dimensional compatibility before mixing connector types in the same system. For guaranteed compatibility, use PLS20 plugs with WS20 sockets from the same manufacturer.\u003c\/p\u003e\n\n\u003ch4\u003eHow do I ground the metal shell for EMI shielding?\u003c\/h4\u003e\n\u003cp\u003eConnect the metal shell to the cable shield (braid) and to the equipment chassis ground. On the cable side: connect the cable braid to the shell via the cable entry clamp or a dedicated ground contact in the connector. On the equipment side: ensure the panel-mount socket (TP20) is electrically connected to the equipment chassis through the mounting nut. A properly grounded metal shell provides 360° EMI shielding around the connector mating interface.\u003c\/p\u003e\n\n\u003ch4\u003eWhat is the maximum pin count for PLS20\/WS20 connectors?\u003c\/h4\u003e\n\u003cp\u003eThe standard range for 20mm aviation connectors is 2–12 pins. For higher pin counts (14–15 pins), some manufacturers offer extended versions. For applications requiring more than 12 circuits in a single connector, consider M23 circular connectors (up to 19 pins) which provide a standardized, higher pin count option with better accessory availability.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial machinery:\u003c\/strong\u003e High-vibration sensor and actuator connections requiring metal shell robustness\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAgricultural equipment:\u003c\/strong\u003e Outdoor multi-circuit connections on tractors and implements\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMarine:\u003c\/strong\u003e Deck equipment connections requiring EMI shielding\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary-adjacent:\u003c\/strong\u003e Field equipment connections requiring robust metal shell construction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStage \u0026amp; entertainment:\u003c\/strong\u003e Multi-circuit outdoor equipment connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003ePLS20\/WS20\/TP20 aviation connector (type and pin count as selected).
