CONTA-CLIP
PK 250
The PK 250 fixed PCB connector from CONTA-CLIP, available on OEM Automatic’s website, is a robust clamping-yoke terminal block designed for secure wire-to-board connections in industrial electronics. This series uses a screw connection system with a clamping yoke mechanism, ensuring excellent contact pressure and vibration resistance. It features a standard pitch of 5.08 mm, with multiple pole configurations (e.g., 2- to 12-pole variants) to suit a variety of circuit designs. The connector is constructed from flame-retardant polyamide 6.6 (UL 94 V-0) and includes brass/steel screw terminals with slotted screws. It typically supports wire sizes up to 2.5 mm² (approx. AWG 12–14) and is rated for up to 24 A at 320 V depending on the configuration. The terminal is also designed for wave soldering, with PCB pin diameters around 1 mm and matching drill hole sizes of about 1.3 mm.
The PK 250 is ideal for use in power supply units, automation controllers, HVAC modules, industrial I/O boards, and building automation systems, where compact, reliable, and secure wire terminations are essential. Its rugged construction ensures long-term mechanical and electrical stability, even under harsh conditions such as vibration or thermal cycling. The modular design allows for straightforward integration into standard PCB layouts, while the screw-type connection simplifies maintenance and field wiring changes. These connectors are especially valued in control cabinet assemblies and electrical distribution boards where reliable performance and compliance with safety standards are critical.
