Automated Testing for Magnetic Latching Relays: Electrical Parameter & Contact Resistance Verification
Magnetic latching relay automated testing validates core electrical parameters including pickup/drop-out voltage, pulse duration and contact resistance via high-speed sensor probing and MES data logging. It eliminates manual measurement deviation and enables full-batch zero-defect sorting for mass relay production.
