High-voltage Reed Relays for pcb mounting
The LI-series realizes the maximum spatial distance between coil and switch in the smallest possible housing. Our design allows isolation voltages of > 4,25 kVDC and resistances > 10 GOhm to be achieved. Breakdown voltages from 250 to 4000 VDC are available for form A contacts. Space saving package of only 30 x 10 x 10,4 mm.
Typical applications:
- High-voltage test systems e.g. cable and in-circuit test equipment
- Battery operated high-voltage test equipment
- Ex-approved applications
