420D - Established Reliability / Military Relay

Download the 420D datasheet PDF. This datasheet also covers the 420 variant, as both devices belong to the same established reliability / military relay family and are provided as variant models within a single manufacturer datasheet.

General 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 1 ampere.

Key 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.

Series 420/422 DPDT Mag-Latching Established Reliability / Military Relay TO-5 RELAYS ESTABLISHED RELIABILITY MILITARY DPDT SERIES  420/422  420D/422D  420DD/422DD RELAY TYPE DPDT basic relay DPDT relay with internal diode for coil transient suppression DPDT relay with polarity reversal protection and coil transient suppression diode 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 1 ampere. Designed for high-density PC board mounting, its small size and low coil power dissipation make the 420 and 422 relays some of the most versatile ultraminiature relays available.
