CL-Series

Picture CL-RelayReed Relays for line sensing

The CL series is used for line sensing in telecommunication devices. It is superior to electronic solutions regarding flashover and impulse strength. Versions with low coil resistance values <10 mA are available.

Characteristics:

  • 1 and 2 coil design available
  • Sealed with UL listed epoxy
  • Magnetic shielding
  • High reliability
  • BABT approved according to EN60950
