CONTA-CLIP
PK 2,5
The PK 2.5 series comprises fixed PCB‑mounted terminal blocks based on the clamping‑yoke screw connection principle. These connectors are available in various pole counts and pitches (commonly 2.5 mm / 2.54 mm, with variants also in 5.00 mm, 5.08 mm, and even 10 mm designs). Each terminal block is constructed with a polyamide 6.6 housing (UL 94 V‑0 flame-rated) and features machined turned metal pins instead of soldered versions, offering superior robustness. The screw clamps and clamping yokes are brass/steel, with slotted screws and a torque rating typically around 0.5 Nm. Current capacities reach up to 16 A at 250 V, with larger 10 mm‑pitch versions rated to 1000 V and 15 A, along with impulse voltage ratings up to 3.5 kV and VDE/UL/cUL certifications. Insulation resistance is ≥ 10¹³ Ω·cm, CTI of 600, glow‑wire ratings GWFI 850 °C / GWIT 775 °C, and they withstand wave‑soldering at 265 °C for 3–4 s. Typical pin diameter is around 1 mm, with drill‑hole sizes near 1.3–1.4 mm and pin lengths ~3.5 mm.
The PK 2.5 clamping‑yoke connectors are well-suited to PCB applications requiring secure, vibration‑proof screw‑terminal wire connections in compact yet demanding environments. They’re ideal for power supplies, control modules, relay interfaces, sensor or actuator connection boards, and compact automation hardware, especially where reliable contact force and mechanical resilience matter. Their modular fixed‑block format simplifies PCB layout and production planning, while the high voltage and current ratings support both signal and low‑power power distribution on the same board. Safety approvals and flame‑retardant materials make these connectors appropriate for industrial, instrumentation, and building‑control electronics where compliance and durability are essential.
