Series 172 DPDT Non-Latching Commercial Electromechanical Relay CENTIGRID COMMERCIAL RELAYS DPDT SERIES RELAY TYPE 172 DPDT basic relay 172D DPDT relay with internal diode for coil transient suppression DESCRIPTION The 172 Centigrid relay is an ultraminiature, hermetically sealed, High force/mass ratios for resistance to shock and vibration. armature relay for commercial applications. Its low profile height (.280) Advanced cleaning techniques provide maximum assurance of and .100 grid spaced terminals, which preclude the need for spreader pads, internal cleanliness. make it an ideal choice where extreme packaging density and/or close PC Precious metal alloy contact material with gold plating assures excellent board spacing are required. high current and dry circuit switching capabilities. The basic operating concept and internal structure are similar to The Series 172 relay has an internal discrete silicon diode for coil transient Teledynes DPDT 114 Centigrid relay. Unique construction features and suppression. manufacturing techniques provide overall high reliability and excellent resistance to environmental extremes: By virtue of its inherently low intercontact capacitance and contact circuit losses, the 172 relay is an excellent subminiature RF switch for The 172 feature: frequencies well into the UHF spectrum (see Figure 1). Applications include telecommunications, test instruments, mobile communications, All welded construction. attenuators, and automatic test equipment. Unique uni-frame design providing high magnetic efficiency and mechanical rigidity.
