About This Product

This slim type relay has a reduced mounting area and has a high voltage withstand voltage of 1,500VAC and a surge voltage of 2,500V.Although it is small, it complies with the EN60950 standard, ensuring the insulation necessary for communication equipment. In addition, it is possible to cut off the large power of 700VAC and 4.2A required for switching equipment, etc.

■Features

・Small and lightweight ・2,500V surge withstand voltage ・Excellent reliability with gold-plated crossbar twin contacts. - Low power consumption of 100 to 230mW due to seesaw balance operation mechanism. ・Although it is small, it has a high withstand voltage of 1,500VAC between the coil contacts and a surge voltage of 2,500V (Telcordia required standard). ・The insulation distance between the coil contacts is 2 mm or more, and there is a high insulation type (ND) that complies with the EN60950 supplementary insulation class required for communication equipment for Europe. ・The contact part has a low thermal electromotive force of approximately 2μV. ・Since it has a sealed resin structure, it can be washed completely.

■Applications

・Exchange machine ・PBX ・Line terminal equipment ・Telephone
