Printed circuit board terminals, also known as PCB terminal blocks or electronic connectors, are essential components for establishing secure and reliable electrical connections on printed circuit boards. These devices are designed with varying pitch sizes, current ratings (typically from 2A to 30A), and voltage ratings (up to 600V depending on the model). They feature screw-type, spring-cage, or push-in connection technologies, and are available in single-level, dual-level, or multi-level configurations. The terminals are often rated for operating temperatures ranging from -40°C to +105°C, with insulation materials like polyamide (PA) or polybutylene terephthalate (PBT) ensuring high dielectric strength. Common pin counts include 2 to 24 poles, and they support wire sizes from 26 AWG to 12 AWG. These components are crucial for signal transmission, power distribution, and control wiring in electronic assemblies.
PCB terminal blocks are widely deployed in industrial automation systems, building management controls, power supply units, and instrumentation panels. They are found in programmable logic controllers (PLCs), variable frequency drives (VFDs), and distributed control systems (DCS). In the renewable energy sector, they are used in solar inverters and wind turbine controllers. Other applications include HVAC systems, lighting control panels, elevator controllers, and railway signaling equipment. Their compact design makes them ideal for high-density wiring in confined spaces, such as in telecommunications equipment and medical devices.
Key subcategories include pluggable PCB terminals (e.g., codes like 1757241 or 1757242), fixed PCB terminals (e.g., 1757243), and angled PCB terminals (e.g., 1757244). The article codes often follow a pattern where the first three digits indicate the series or pitch size (e.g., 175 for 5.08 mm pitch), the next three digits denote the number of poles (e.g., 724 for 24 poles), and the final digit specifies the connection type (e.g., 1 for screw, 2 for spring). Other relevant items include double-level terminals (e.g., 1757245) and high-current terminals (e.g., 1757246). These codes are standardized across manufacturers like Phoenix Contact, Weidmüller, and WAGO.
