Small frame contactors with new functions join the SC series. The SC line up, which is based on high level technology, now extends from the SC-03 to the SC-N16. The SC series contactors have such options as additional auxiliary contact blocks and operation counter unit with snap-on fittings, and coil surge suppressors. Modification can be made quickly and easily on site. Improved contact materials and structure double the electrical life compared with existing contactors 2 million operations. Bifurcated type auxiliary contacts have a high degree of contact reliability. Therefore, they can be used in low-level circuits of 5V, 3mA and directly input to electronic equipment..
