ER421D - Relays

Download the ER421D datasheet PDF. This datasheet also covers the ER421 variant, as both devices belong to the same relays family and are provided as variant models within a single manufacturer datasheet.

Description

The magnetic-latching TO-5 relay, originally conceived and developed by Teledyne, has become one of the industry standards for low-level switching from dry circuit to 0.5 ampere.

Features

  • and manufacturing techniques provide excellent resistance to environmental extremes and overall high reliability:.
  • All welded construction.
  • Unique uni-frame design providing high magnetic efficiency and mechanical rigidity.
  • High force/mass ratios for resistance to shock and vibration.
  • Advanced cleaning techniques provide maximum assurance of internal cleanliness.
  • Precious metal alloy contacts material with gold plating assures excellent high curre.
