CONTA-CLIP

PKBZ 1551

The PKBZ 1551 connector series by CONTA‑CLIP comprises pluggable female socket terminal blocks designed for PCB integration using a screw‑connection principle. Available in variants with two to twelve poles, all spaced on a 3.81 mm pitch, they share robust ratings: 160 V nominal voltage, 8 A current, and 2.5 kV impulse voltage under overvoltage category III and contamination degree 3. Each pole accepts conductors from 0.14 mm² to 1.5 mm² (AWG 28–16) or stranded wire up to 1 mm² with ferrules, using an M2 screw tightened to 0.25 Nm torque and a stripping length of 7 mm. Constructed with a polyamide 6.6 housing rated UL 94 V‑0, bronze contact springs and brass clamp elements, the series withstands -30 °C to +105 °C operating temperature and meets UL, cUL, and VDE safety approvals, with explicit VDE rating of 160 V/8 A and UL/cUL use‑group voltage up to 300 V. It is also rated for creepage resistance (CTI 600), insulation resistance ≥ 1 × 10¹³ Ω·cm, and glow‑wire performance: GWFI 850 °C with 30 s after‑glow and GWIT 775 °C exposure time 5 s.

The PKBZ 1551 series is ideal for modular PCB‑mounted connection systems in industrial automation, machinery control electronics, and switchgear interfaces where removable connectors support flexible wiring layouts and maintenance. The pluggable female sockets allow fast mating with corresponding PKB plug headers for secure detachable interconnects. Designers commonly choose the 6‑pole (Art.-Nr. 13043.1), 9‑pole (14067.1) or 12‑pole (13049.1) versions depending on signal density and board space constraints, with widths ranging from approximately 22.9 mm to 45.7 mm accordingly. With vertical‑upward wire entry at 90°, these connectors facilitate tidy cable routing in tight enclosures, while UL and VDE approvals make them suitable for global export applications. They perform reliably in harsh environments demanding high safety margins and enable up to 100 plug/unplug cycles plus 5 connection cycles per terminal, supporting regular service and reconfiguration with minimal wear.
