SERIES 172 CENTIGRID® COMMERCIAL RELAYS DPDT SERIES DESIGNATION RELAY TYPE 172 DPDT basic relay 172D DPDT relay with internal diode for coil transient suppression INTERNAL CONSTRUCTION DESCRIPTION The 172 Centigrid® relay is an ultraminiature, hermetically sealed, armature UPPER STATIONARY CONTACT UNI-FRAME relay for commercial applications. Its low profile height (.280") and .100" grid spaced terminals, which preclude the need for spreader pads, make it an ideal ARMATURE LOWER STATIONARY CONTACT choice where extreme packaging density and/or close PC board spacing are required. MOVING CONTACT The basic operating concept and internal structure are similar to Teledyne’s DPDT 114 Centigrid® relay. Unique construction features and manufacturing techniques provide overall high reliability and excellent resistance to environmental extremes: • All welded construction. 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. ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS The Series 172 relay has an internal discrete silicon diode for coil transient –65°C to +125°C Temperature Storage (Ambient) Operating –55°C to +85°C suppression. Vibration (General Note 1) 10 g’s to 500 Hz By virtue of its inherently low intercontact capacitance and contact circuit Shock (General Note 1) 30 g’s, 6 msec, half-sine Enclosure Hermetically sealed Weight 0.15 oz. (4.3g) max. 172 Page 91 losses, the 172 relay is an excellent subminiature RF switch for frequencies well into the UHF spectrum (see Figure 1). Applications include telecommunications, test instruments, mobile communications, attenuators, and automatic test equipment.
