About This Product

This is a 50mW low power consumption slim type ED2 relay that supports surface mounting. Furthermore, we have also prepared a highly reliable type with optimal terminal dimensions that alleviates terminal stress and can be expected to have a long connection life.

■Features

・Ultra low power consumption ・Surface mounting compatible ・2,500V surge withstand voltage ・High-density mounting type available - Low power consumption with rated power consumption of 50 to 70mW due to high efficiency magnetic circuit. ・In addition to the general type, high-density mounting type and high connection reliability type are also available. ・Excellent reliability with gold-plated crossbar twin contacts. ・High withstand voltage of 1,500VAC between coil contacts and surge voltage of 2,500V. ・The contact part has a low thermal electromotive force of approximately 0.5μV. ・Since it has a sealed resin structure, it can be washed completely.

■Applications

・Exchange machine ・PBX ・Line terminal equipment ・Telephone
