PKDR 2,5

The PKDR 2,5 series from Conta-Clip is a double-level PCB terminal block system designed to maximise wiring density while ensuring safe and reliable connections. With a 5.00 mm pitch, these terminals accept conductors up to 2.5 mm² (AWG 14), support currents of 13 A at 250 V, and provide an impulse voltage resistance of 4 kV, meeting the requirements of overvoltage category III and pollution degree 3. Each terminal uses a 1 mm solder pin for PCB mounting, paired with M2.5 screws tightened to 0.6 Nm, and requires a 7 mm stripping length for conductors, offering a secure and vibration-resistant connection. Built from flame-retardant polyamide 6.6 (UL 94 V-2) with steel and copper contact materials, the PKDR 2,5 is engineered for durability, heat resistance, and compatibility with wave soldering processes, making it well-suited to modern assembly methods.

The PKDR 2,5 provides a compact, high-density solution for PCB-based control systems, automation equipment, and interface modules where board space is limited but reliable terminations are critical. Its double-level design doubles connection capacity without enlarging the PCB footprint, making it ideal for industrial control cabinets, signal distribution, and sensor wiring arrays. Certifications including CSA and UL approvals expand its suitability for global applications, while features such as high creepage resistance, glow-wire compliance, and operation across –30 °C to +105 °C ensure long-term performance even in demanding environments. As a result, the PKDR 2,5 is a practical choice for engineers seeking robust, space-efficient, and standards-compliant terminal blocks for dense and durable PCB interconnections.
