CONTA-CLIP
PK 120
The PK 120 series from Conta-Clip is a line of vertical, solder-type PCB terminal blocks designed for secure and efficient wire-to-board connections in demanding industrial environments. With a 5.08 mm pitch, wire-protection screw connections, and vertical wire entry, the PK 120 ensures reliable contact while optimising space on the circuit board. The terminals support conductors up to 2.5 mm², carry currents of up to 24 A at 250 V, and feature solder pins (1 mm in diameter, 3.8 mm length) for stable mounting. Engineered for durability, the blocks offer high insulation resistance, withstand impulse voltages up to 2 kV, and maintain performance across a wide temperature range from –40 °C to +105 °C, all while meeting the UL 94 V-0 flammability standard.
These properties make the PK 120 particularly suitable for industrial automation, control systems, and energy distribution modules where reliable, vibration-resistant connections are essential. Their robust screw clamp design ensures safe conductor fastening without damage, simplifying installation and maintenance in the field. With a compact footprint and resilience against harsh conditions, the PK 120 terminal blocks are widely applied in control panels, building automation, and transport systems, offering engineers a dependable and space-efficient solution for long-term, safety-critical PCB interconnections.
