DESCRIPTION

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 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 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 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 external

holding power is required.

The magnetic latching feature of the Series S422 relays

provide a “memory” capability, since the relays will not

reset upon removal of coil power.
