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 expressly
for high density PC Board mounting, its small size and low coil dissipation make the TO-5
relay one of the most versatile ultraminiature relays available.
The High Temperature Series of TO-5 Relays are designed for reliable operation in elevated
ambient temperatures up to 200C. Special material selection and processing provide
assurance of freedom from contact contamination and mechanical malfunctioning that might
otherwise be caused by ultra high ambient temperature conditions.

• High temperature industrial and process control instrumentation
By virtue of its inherently low intercontact capacitance and contact circuit losses, the TO-5
relay has shown itself to be an excellent ultraminiature RF switch for frequency ranges well
into the UHF spectrum (see Figures 1 and 2).

PRINCIPLE OF OPERATION 422H
Enclosure
All welded, hermetically sealed
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 the
nominal 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.

NOTES:
1. Characteristics shown as “typical” are based on available data and
are best estimates. No on-going verification tests are performed.
2. Characteristics are subject to change after life.
3. Relays will exhibit no contact chatter in excess of 10 µsec or
transfer in excess of 1 µsec.
4. Measured in nominal coil voltage at 25°C.
5. Not applicable to 422H Series.
6. Contact load ratings and contact life ratings are based on similarity
testing at 125°C. No 200°C testing is performed.
