INTERNAL CONSTRUCTION DESCRIPTION
The 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
UNI-FRAME
coil power dissipation make the 432 relay one of the most versatile
UPPER
ultraminiature relays available.
STATIONARY
CONTACT
The following unique construction features and manufacturing techniques
ARMATURE
provide excellent resistance to environmental extremes and overall high
LOWER
reliability.
STATIONARY
CONTACT
All welded construction.
Unique uni-frame design, providing high magnetic efficiency and
mechanical rigidity.
MOVING
CONTACT
High force/mass ratios for resistance to shock and vibration.
Advanced cleaning techniques provide maximum assurance of internal
cleanliness.
Precious metal alloy contact material with gold plating assures excellent
high current and dry circuit switching capabilities.
ENVIRONMENTAL AND
The Series 432D and 432DD relays have internal discrete silicon diodes for
