1704521

The Phoenix Contact 1704521 is a 6-position terminal block header designed for PCB mounting. It features a 5.00mm pitch between positions and a single level layout. The header is oriented vertically and uses through hole mounting with solder termination, making it suitable for permanent board connections. The male pins are partially shrouded to guide mating with corresponding plugs, and the contacts have a tin plating finish for reliable conductivity. The housing is black. Electrically, it is rated for 300V voltage and 10A current, positioning it for moderate power signal and distribution applications in industrial control, automation, and building infrastructure. This component belongs to the broader connectors and interconnects category, specifically terminal block headers, plugs, and sockets. As a header, it serves as the board-side interface for detachable wiring connections. The 5mm pitch aligns with common terminal block standards, ensuring compatibility with a wide range of plug connectors from Phoenix Contact and other manufacturers. Designers should note the vertical orientation requires adequate clearance above the PCB, and the through hole packaging provides robust mechanical retention.
