CONTA-CLIP
PZK 3191
The PZK 3191 series from Conta-Clip is a range of tension-spring connection PCB terminal blocks designed for compact and reliable wire-to-board connections. These terminals feature a 2.5 mm pitch and are available in configurations ranging from 2 to 12 poles, with widths of 5.0 mm to 32.0 mm, respectively. They support conductor cross-sections from 0.08 mm² to 1.0 mm² for rigid wires and up to 0.5 mm² for stranded wires with ferrules. The terminals are rated for a maximum current of 9 A and a voltage of 130 V, with an impulse voltage resistance of 1.25 kV, making them suitable for applications requiring high electrical performance. They feature a solder connection type with a 45° PCB-to-wire connection angle, ensuring secure and vibration-resistant terminations. Constructed from flame-retardant polyamide 6.6 (UL 94 V-0), these terminal blocks offer durability and compliance with international safety standards.
The PZK 3191 series is ideal for use in industrial control systems, automation equipment, and power distribution modules, where space-saving and reliable connections are essential. The tension-spring connection system allows for quick and tool-free wiring, enhancing assembly efficiency and reducing labour costs. The compact design facilitates easy integration into dense PCB layouts and enclosures. With certifications including UL 1059, CSA 22.2 No.158, and VDE, the PZK 3191 series meets international safety standards, making it suitable for global applications in demanding environments. Whether for new designs or retrofitting existing systems, these terminal blocks provide engineers with a dependable solution for dense and durable PCB interconnections.
