Tech Lowdown

Sealevel offers optional spring clamp terminal blocks for SeaI/O, SeaDAC, SeaDAC Lite modules and other devices with 3.5mm centerline spacing. The terminal blocks are keyed to prevent incorrect or upside down installation and the lever-style clamping mechanism requires no tools making field installation easy. The clamping mechanism provides superior wire retention by automatically adjusting the spring tension on wire diameters from 16-28 AWG.

Upgrade your SeaI/O modules with spring clamp terminal blocks using the ST-SP9-KT, which includes eight 5-position and one 6-position spring clamp terminal blocks. Spring clamp and screw terminal blocks are also available in packs of ten.
