Miniature signal relay EF2 series
EM Device Co., Ltd.
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
