Technical Advantages

Why Industrial OEM Designers Specify CAMTEC UMS Relays

Traditional electromechanical relays used in DC circuits suffer from destructive electric arcing during contact opening. The CAMTEC UMS solid-state semiconductor relay eliminates arcing, contact bouncing, and acoustic noise entirely.

  • >100 Million Switching Operations: Zero mechanical moving parts ensure infinite switching life without contact erosion.
  • High Surge Current Tolerance: Designed to withstand 10ms surge loads up to 4x rated nominal current.
  • Fast Microsecond Response Time: Enables high-frequency switching cycles far exceeding mechanical contactor speeds.
  • TS35mm DIN-Rail Mounting: Fits directly into standard industrial electrical control cabinets (EN 60715).
  • Made in Germany: Fabricated at our TÜV-audited site in Pfinztal, fully compliant with ISO 9001:2015, CE, RoHS, and REACH.
