STL 990

The STL 990 series from Conta-Clip is a robust range of male pin blocks designed for secure and reliable wire-to-board connections in demanding applications. With a 5.08 mm pitch, these terminal blocks are available in configurations ranging from 2 to 15 poles, accommodating conductor cross-sections from 0.2 mm² to 4 mm² for rigid wires and up to 2.5 mm² for wires with ferrules. The terminals are rated for a maximum current of 10 A and a voltage of 250 V, with an impulse voltage resistance of 4 kV, making them suitable for applications requiring high electrical performance. They feature a 1 mm diameter connecting pin with a 1.4 mm drill hole diameter, 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.

In practical applications, the STL 990 series is ideal for use in industrial control systems, automation equipment, and power distribution modules, where space-saving and reliable connections are essential. The 45°/135° PCB/contact angle facilitates easy integration into compact PCBs and enclosures. The male pin blocks are designed for plug-in connectors, allowing for quick and tool-free wiring, enhancing assembly efficiency and reducing labour costs. With certifications including overvoltage category III, pollution degree 3, and creepage-current resistance (CTI) 600, the STL 990 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.
