420DD - Established Reliability / Military Relay
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
420DD 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
