Series 420/422 DPDT Non-Latching 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 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.
●The Series 420D/422D and 420DD/422DD utilize discrete diodes for coil suppression and polarity reversal protection.
●By virtue of its inherently low intercontact capacitance and contact circuit losses, these TO-5 relays have proven to be excellent ultraminiature RF switches for frequency ranges well into the UHF spectrum. A typical RF application for these TO-5 relays is in handheld radio receivers, wherein the combined features of good RF performance, small size, very low coil power dissipation and high reliability make it a preferred method of transmit-receive switching
●The Series 420/422 magnetic-latching relays are ideally suited for applications where power dissipation must be minimized. The relays can be operated with a short duration pulse. After the contacts have transferred, no external holding power is required.
●The magnetic latching feature of the Series 420/422 relays provide a “memory” capability, since the relays will not reset upon removal of coil power.
