SERIES CENTIGRID S172 SURFACE MOUNT COMMERCIAL RELAYS DPDT SERIES RELAY TYPE DESIGNATION S172 DPDT basic relay S172D DPDT relay with internal diode for coil transient suppression INTERNAL CONSTRUCTION DESCRIPTION UNI-FRAME The S172 surface mount Centigrid relay is an ultraminiature, hermetically sealed, armature relay for commercial applications. Its low profile height (.470) ARMATURE and .100 grid spaced terminals make it an ideal choice where extreme UPPER STATIONARY CONTACT packaging density and/or close PC board spacing are required. The specially MOVING CONTACT formed leads are pre-tinned to make the relays ideal for all types of surface- LOWER STATIONARY CONTACT mount solder reflow processes. The basic design and internal structure are similar to Teledynes DPDT 114 Centigrid relay. Unique construction features and manufacturing techniques provide overall high reliability and excellent resistance to environmental extremes: All welded construction. Unique uni-frame design providing high magnetic efficiency and mechanical ENVIRONMENTAL AND rigidity. PHYSICAL SPECIFICATIONS High force/mass ratios for resistance to shock and vibration. Storage 65C to +125C Temperature (Ambient) Advanced cleaning techniques provide maximum assurance of internal 55C to +85C Operating cleanliness. Vibration 10 gs to 500 Hz (General Note 1) Precious metal alloy contact material with gold plating assures excellent Shock 30 gs, high current and dry circuit switching capabilities. (General Note 1) 6 msec, half-sine Enclosure Hermetically sealed Weight 0.15 oz. (4.3g) max. The S172D relay has an internal discrete silicon diode for coil transient 260C max. temp. suppression.
