METZ CONNECT’s SM99 and SR99 are spring-clamp terminal blocks which have a compact footprint, and accept wire sizes up to 16 AWG.
The SM99 blocks are for surface-mount assembly, and the SR99 are for through-hole mounting. Both types are reflow-capable according to the JEDEC 20 MSL 1 standard.
Featuring a push-in method for wire insertion and a large finger push-button for wire release, they are easy to install and use.
The SM99 and SR99 series offer good connection reliability, thanks to a wire connection indicator and a test point for a continuity check. They give the board designer great flexibility, as they can be placed as single poles nearly anywhere on a PCB.
METZ CONNECT terminal blocks: Available in versions for surface and through-hole mounting
