EC2/EE2 Series Data

Features

The NEC EE2 series relays are low power consumption, low magnetic interference surface mount relays that meet 2500V surge requirements(between coil and contacts). Their compact lightweight design makes them ideal for use in telecommunication equipment. This series complies with FCC Part 68 2500V surge voltage requirements.

The EE2 series is available in 2 form C (DPDT) contact arrangements for all latch types. The EE2 series also offers a minimum foot print design as well as a tape and reel packaging system.

CSAUR
  • Compact and lightweight
  • 2 form C contact arrangement
  • Low power consumption: 100 to 140mW
  • Reduced mounting space: 15 mm x 9.5 mm
  • High-breakdown voltage of coil to contacts: 1500 Vac, 2500 V (2 x 10 µs*)
  • Capable of high-power switching: 700 Vac, 4.2 A, 4 times in case of accident
  • UL recognized (E73266), CSA certified (LR46266)
  • Certified to EN 60950
  • NKX type guarantees 1.5kVAC withstanding voltage on the normally open contacts

Applications

Electronic switching systems, PBX, terminal equipment, telephone system.

Note
* Test by pulse voltage
** S : Set coil (pin No.1... +, pin No.5... - ) R : Reset coil (pin No.10... , pin No.6... - ) The latch type relays should be initialized to the reset position prior to using and should be energized to specific polarity by above polarity to avoid wrong operation.
