The 1990009 is a two-row, green PCB terminal block designed for wave soldering mounting. It features two positions with a 2.5 mm pitch, a push-in spring connection method for easy wire termination, and a conductor entry angle of 45° relative to the PCB. This component is rated for a nominal current of 2 A and a nominal voltage of 250 V, supporting conductor cross-sections from 24 to 20 AWG. Its compact design and offset, zigzag pinning provide increased dielectric strength and mechanical stability, making it suitable for applications requiring reliable board-to-wire connections.
