420D - TELEDYNE

420D 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 of the most versatile ultraminiature relays available. The .

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. The Series 420D/422D and 420DD/422DD utilize discrete diodes for coil suppression and polarity r.
