TELEDYNE RELAYS Everywhereyoulook" Series 172 DPDT Non-Latching Commercial Electromechanical Relay Sliljj DESCRIPTION The 172 Centigrid® relay is an ultraminiature, hermetically sealed, armature 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 choice where extreme packaging density and/or close PC board spacing are required. 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: The 172 feature: • 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. The Series 172 relay has an internal discrete silicon diode for coil transient suppression. By virtue of its inherently low intercontact capacitance and contact circuit 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. 172 Y M4 Relay Series Ground Pin Option i (See Appendix) Pad Option (See Appendix) 26 / S Q Q = Solder-Coated Leads1 G = Gold-Plated Leads (RoHS Compliant) R = RoHS Compliant Solder2 S = 0.187” Leads No Suffix = 0.75” Leads Nominal Coil Voltage (26 = 26.5 V, See Page 2 for more Voltages) © 2018 TELEDYNE RELAYS (800) 284-7007 • www.teledynerelays.com
