Designed for highdensity 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: • Oil exploration (down hole) instrumentation • High temperature industrial and process control instrumentation ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS 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). Temperature (Ambient) –65°C to +200°C Vibration (General Note 1) 30 g’s to 3000 Hz Shock (General Note 1) 75 g’s, 6 msec, half-sine Acceleration 50 g’s PRINCIPLE OF OPERATION 422H Hermetically sealed Energizing Coil B produces a magnetic field COIL A COIL B opposing the holding flux of the permanent magnet SOFT IRON in Circuit B. As this net holding force decreases, the SOFT IRON CORE A CORE B attractive force in the air gap of circuit A, which also AIR GAP SOFT IRON results from the flux of the permanent magnet, ARMATURE STATIONARY CONTACT 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 MOVING CONTACT 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. Enclosure 412H 0.09 oz.

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.
