The 3357-6525-1C is a 25-position D-Sub EMI junction shell that provides robust shielding against electromagnetic and electrostatic interference. Constructed from nickel-over-copper plated ABS plastic, the shell operates within a temperature range of 0°C to +75°C. It includes a thermoplastic elastomer compression insert with a UL 94V-0 flammability rating and zinc-plated steel hardware for secure assembly. The lightweight, compact design features integrated strain relief that compensates for multiple cable diameters, making it a versatile solution for reducing assembly time and cost in various electronic applications.
