Electric Vehicles (EV) & Charging

The Challenge: Modern EVs are moving to 800V architectures. Disconnecting a high-voltage battery under load creates a dangerous DC arc that can melt standard contacts.

The MiRelay Solution: Hydrogen Arc Extinction

Our EVM & ESM Series feature hermetically sealed ceramic chambers filled with pressurized Hydrogen gas. This rapidly cools the arc, allowing for safe disconnection of up to 1000V-1500V DC loads.

Semiconductor & ICT Testing

The Challenge: Testing chips and wafers requires thousands of switching cycles per second. Signal integrity is critical; any “contact bounce” creates false failures.

The MiRelay Solution: Zero Bounce & High Density

Our Mercury Wetted Relays (HG Series) offer a self-healing liquid contact with ZERO bounce. For high-density matrix boards, our MSIP Series offers a 50% smaller footprint than standard relays.

Life Sciences

Medicinaj Aparatoj

The Challenge: Defibrillators generate massive 5kV pulses to restart the heart. The sensitive monitoring electronics must be instantly isolated to prevent destruction.

The MiRelay Solution: 20kV Isolation

Our Serio HVR utilizes Tungsten contacts and vacuum sealing to withstand up to 20kV isolation voltage, protecting patient monitors during the defibrillation pulse.

Transport & Fluid Sensing

The Challenge: Trucks and Generators operate in high-vibration, dirty environments. Capacitive sensors fail due to water contamination; mechanical arms break.

The MiRelay Solution: Hermetic Reed Sensing

Our FLS-H (Heavy Duty) and AdBlue Sensors use magnetic floats with electronics sealed inside a stainless steel or aluminum tube (IP67). They are immune to foam, dirt, and vibration.

Cable & Hipot Testing

The Challenge: Verifying the insulation of miles of cable requires high voltage switching that won’t degrade over time.

The MiRelay Solution: High Voltage Mercury

La MH Series is unique in the world. It combines High Voltage isolation (up to 10kV) with Mercury contacts, allowing for stable resistance testing even at high voltages.
