ER421 - Relays
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.
Designed for high-density PC board mounting, its small size and low coil power dissipation make the 421 relay one of the
ER421 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
