Miniature signal relay UD2 series
EM Device Co., Ltd.
About This Product
This is a next-generation surface-mount miniature signal relay with a mounting area about half that of the conventional EB2 series. Although it is small, it has low power consumption, and the surge resistance between the coil contacts is 2,500V, ensuring the insulation necessary for communication equipment.
■Features
・Ultra small/low height type
・High voltage resistance
・Low power consumption type available
- Space-saving flat shape allows high-density mounting
・High withstand voltage specifications: 2,500V (2×10μs) surge resistance between coil contacts and 1,500V (10×160μs) surge resistance between open contacts
・Compliant with IEC60950/UL1950/EN60950 insulation distance requirements and withstand voltage requirements (basic insulation class, 200V operating voltage)
- Rated power consumption is 140mW, and a low power consumption type of 100mW is also available.
・Gold-plated crossbar twin contacts provide excellent reliability.
■Applications
・Exchange machine
・PBX
・Line terminal equipment
・Telephone
