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, these TO-5 relays are some of the most versatile
ultraminiature relays available because of their small size and low coil power dissipation.
The H Series high-temperature TO-5 relays are designed for reliable operation in
elevated ambient temperatures up to 200°C. 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.
Typical applications:
By virtue of its inherently low intercontact capacitance and contact circuit losses, the H
Series relays have proven to be excellent ultraminiature RF switches for applications with
frequency ranges well into the UHF spectrum (see Figures 1 and 2).
PRINCIPLE OF OPERATION 422H
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.
