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 coil power dissipation make the 431 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 contact material with gold plating assures excellent
   high current and dry circuit switching capabilities.
