ER421-5A产品概述
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 most versatile
ultraminiature relays available.
The following unique construction 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 current and dry circuit switching capabilities.
