The SS-7188S-A-PG4-BA-50 is an 8-position, 8-contact shielded modular jack intended for through-hole PCB mounting. It features a one-piece EMI-RFI shield for interference protection and includes provisions for ESD grounding. The contacts are a copper alloy with 50 micro-inches of selective gold plating in the mating area, and the housing is constructed from UL94 V-0 rated thermoplastic. This connector is designed to comply with TIA-1096 standards and has a dielectric withstanding voltage of 2250VDC between the contacts and shield. It is ideal for use in networking equipment and other devices requiring reliable Category 5/5e Ethernet connectivity.
