The 1355437-2 is a wire seal component designed for use with AMP MCP 9.5 two-position connectors in harsh environment applications. It accommodates wire insulation diameters of 5.8 mm to 6.6 mm and is specifically rated for 10 mm² wire cross-sections. The seal is colored sky blue for easy identification and works in conjunction with the connector system to provide IP 67 and IP 69K protection ratings (with backshell), protecting connections from dust, dirt, and moisture in demanding environments. This wire seal is essential for maintaining environmental sealing integrity in wire-to-wire and wire-to-board connections subject to severe vibration and mechanical shock.
