HIGH-PERFORMANCE

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 TO-5

relay one of the most versatile subminiature relays available.

The K Series high-shock TO-5 relays are designed to withstand shock levels up to 4000

g’s, .5 millisecond duration. Special material selection and construction details provide

assurance that critical elements of the relay structure and mechanism will not be

permanently displaced or damaged as a result of extremely high g level shocks.

Typical applications:

• Commercial avionics aircraft control

• Commercial aircraft control systems

• Transportation systems (rail/truck)

By virtue of their inherently low intercontact capacitance and contact circuit losses, the

K Series relays have proven to be excellent subminiature RF switches for applications

with frequency ranges well into the UHF spectrum. A typical RF application for the TO-5

relay is in handheld radio transceivers, wherein the combined features of good RF

performance, small size, low coil power dissipation and high reliability make it a

preferred method of T-R switching (see Figure 1 and 2).

PRINCIPLE OF OPERATION 422K

Energizing Coil B produces a magnetic field

opposing the holding flux of the permanent magnet

in Circuit B. As this net holding force decreases, the

attractive force in the air gap of circuit A, which also

results from the flux of the permanent magnet,

becomes great enough to break the armature free of

Core B, and snap it into a closed position against

Core A. The armature then remains in this position

upon removal of power from Coil B, but will snap

back to position B upon energizing Coil A. Since operation depends upon cancellation

of a magnetic field, it is necessary to apply the correct polarity to the relay coils as

indicated on the relay schematic.

When latching relays are installed in equipment, the latch and reset coils should not be

pulsed simultaneously. Coils should not be pulsed with less than rated coil voltage and

the pulse width should be a minimum of three times the specified operate time of the

relay. If these conditions are not followed it is possible for the relay to be in the

magnetically neutral position.
