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. Typical usage: 422H ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS Temperature (Ambient) Vibration -65˚C to + 200˚C Shock 75 g’s for 6 msec. (Note 3) half-sine 30 g’s to 3000 Hz (Note 3) • Oil exploration (down hole) instrumentation • 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). Acceleration 50 g’s (Note 3) 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.

PERMANENT MAGNET MAGNETIC CIRCUIT B COIL B SOFT IRON CORE B SOFT IRON ARMATURE MAGNETIC CIRCUIT A SOFT IRON FRAME COIL A SOFT IRON CORE A AIR GAP STATIONARY CONTACT MOVING CONTACT 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. 65 SERIES 412H/422H/432H GENERAL ELECTRICAL SPECIFICATIONS (-65°C to +125°C unless otherwise noted) (Notes 1 & 2) Release Time (Note 4 & 5) Contact Bounce lntercontact Capacitance Insulation Resistance Dielectric Strength 2 Form C (DPDT) Continuous 412H/432H: 0.125 ohms max. before life; 0.225 ohms max. after life at 1A/28VDC (measured 1/8” below header.) 422H: 0.15 ohms max. before life; .25 ohms max. after life/1A/28VDC Resistive: 1 Amp/28VDC Inductive: 200 mA/28VDC (320 mH) Lamp: 100 mA/28VDC Low Level: 10 to 50 µA/10 to 50 mV Resistive: 250 mA/115VAC, 60 and 400Hz (Case not grounded) 100 mA/115VAC, 60 and 400Hz (Case grounded) 10,000,000 cycles (typical) at low level 01,000,000 cycles (typical) at 0.5A/28VDC resistive 00,100,000 cycles min. at all other loads specified above 2A/28VDC Resistive (100 cycles min.)
