SERIES SURFACE MOUNT MAGNETIC-LATCHING TO-5 RELAYS DPDT SERIES DESIGNATION S422 RELAY TYPE DPDT Surface Mount Basic Relay S422D DPDT Surface Mount Relay with internal diode for coil transient suppression S422DD DPDT Surface Mount Relay with internal diode for coil transient suppression and polarity reversal protection The Series S422D and S422DD utilize discrete diodes for coil suppression and polarity reversal protection. DESCRIPTION The magnetic-latching 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 surface mounting, its small size and low coil power dissipation make the S422 relay one of the most versatile ultraminiature relays available. The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high reliability: • All welded construction. • Unique uni-frame design providing high magnetic efficiency and mechanical rigidity. • High force/mass ratios for resistance to shock and vibration. • Advanced cleaning techniques provide maximum assurance of internal cleanliness. • Precious metal alloy contact material with gold plating assures excellent high current and dry circuit switching capabilities. PRINCIPAL OF OPERATION PERMANENT MAGNET MAGNETIC CIRCUIT B By virtue of its inherently low intercontact capacitance and contact circuit losses, these TO-5 relays have proven to be excellent ultraminiature RF switches for frequency ranges well into the UHF spectrum. A typical RF application for these TO-5 relays is in handheld radio receivers, wherein the combined features of good RF performance, small size, very low coil power dissipation and high reliability make it a preferred method of transmit-receive switching (See Figure 1). The Series S422 magnetic-latching relays are ideally suited for applications where power dissipation must be minimized. The relays can be operated with a short duration pulse. After the contacts have transferred, no external holding power is required. The magnetic latching feature of the Series S422 relays provide a “memory” capability, since the relays will not reset upon removal of coil power. MAGNETIC CIRCUIT A SOFT IRON FRAME Energizing Coil B produces a magnetic field op+ + posing the holding flux of the permanent magnet in COIL A COIL B Circuit B. As this net holding force decreases, the SOFT IRON SOFT IRON COIL A COIL B attractive force in the air gap of Circuit A, which AIR GAP SOFT IRON also results from the flux of the permanent magARMATURE STATIONARY CONTACT net, 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 MOVING CONTACT position upon removal of power from Coil B, but will snap back into 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 magnetic neutral position. © 2008 Teledyne Relays S422 ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS Temperature (Ambient) –65°C to +125°C Vibration (General Note 1) 30 g’s to 3000 Hz Shock (General Note 1) 100 g’s, 6msec, half sine Acceleration 50 g’s Enclosure Hermetically sealed Weight 0.10 oz.
