DESCRIPTION
The magnetic-latching TO-5 relay, originally conceived and developed by Teledyne, has bee one of the industry standards for low-level switching from dry circuit to 1 ampere. Designed for high-density PC board surface mounting, its small size and low coil power dissipation make the S422 relay one of the most versatile ultraminiature relays available.
S422 Features
:
- 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.
The Series S422D and S422DD 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 bined 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 S422 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...
