CONTA-CLIP
PKB 4350
The PKB 4350 series consists of push‑in female socket plug blocks designed to mate with male pin connectors (such as the ISTLZ 950 series) in pluggable PCB assemblies. These blocks likely feature a 5.08 mm pitch, available in multi‑pole configurations (commonly from 2 to 12 poles), and are built on CONTA‑CLIP’s proven spring‑pressure push‑in connection system. The housing is typically made from polyamide 6.6, UL 94 V‑0 rated, with high insulation resistance, CTI of 600, and glow‑wire compliance (GWFI 850 °C / GWIT 775 °C). Metallic female contacts clamp solid or ferruled conductors, support rated currents in the range of 6–12 A, insulated up to 250 V, and match international safety approvals like UL 1059, cUL CSA 22.2 No. 158, and EN 61984.
PKB 4350 socket blocks are used to construct pluggable PCB-to-PCB or PCB-to-wire interface modules, commonly found in relay bases, power control boards, automation panels, and modular interface units. The push‑in system allows tool-free and rapid insertion of conductors, speeding assembly and reducing wiring errors, while the female socket design ensures secure and vibration-resistant mating with corresponding male headers. This plug-and-play approach facilitates maintenance, wiring changes, or module replacement without solder rework—ideal for industrial control cabinets, building services automation, and embedded electronic systems where reliable and service-friendly connections are essential.
