Insulation Resistance

Measuring the Unmeasurable

In applications like mass spectrometry, in-circuit testing (ICT), and medical instrumentation, the relay must present a near-infinite impedance when open. Any leakage current through the relay can corrupt the measurement of femto-amp signals.

Achieving 100 Tera-Ohms

Standard relays may offer 1 GΩ insulation. MiRelay’s HRX Series utilizes specialized glass formulations and potting compounds to achieve insulation resistance greater than 100 TΩ ($10^{14} \Omega$).

We perform 100% testing on these units using specialized electrometers to guarantee leakage performance.
