SA120-2.54 PCB Screw Terminal Block is designed for compact and reliable wire-to-board connections in electronic and low-voltage control applications. Featuring a 2.54mm pitch, this terminal block is suitable for high-density PCB layouts where space efficiency and stable electrical performance are required.
With a screw termination structure, the SA120 series provides secure conductor fixation and consistent contact, making it a practical solution for permanent or semi-permanent PCB connections.

This PCB-mounted terminal block uses a traditional screw clamping mechanism to connect conductors directly to the printed circuit board. The design ensures stable mechanical retention of the wire and reliable electrical contact over long-term operation.

The 2.54mm pitch allows for compact terminal spacing, making the SA120 series suitable for small electronic modules and control circuits where board space is limited.
