Series 114 DPDT Non-Latching Established Reliability / Military Relay CENTIGRID ESTABLISHED RELIABILITY MILITARY DPDT SERIES RELAY TYPE 114 DPDT basic relay 114D DPDT relay with internal diode for coil transient suppression 114DD DPDT relay with internal diodes for coil transient suppression and polarity reversal protection DESCRIPTION The 114 sensitive Centigrid relay retains the same features as the 114 High force/mass ratios for resistance to shock and vibration. standard Centigrid relay with only a minimal increase in profile height Precious metal alloy contact material with gold plating assures excellent (.275 in.). Its .100-inch grid spaced terminals, which preclude the need for high current and dry circuit switching capabilities. spreader pads, and its low profile make the 134 relay ideal for applications where high packaging density is important. The Series 114D and 114DD have internal discrete silicon diodes for coil suppression and polarity reversal protection. The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high reliability: By virtue of its inherently low intercontact capacitance and contact circuit losses, the 114 relay has proven to be an excellent ultraminiature RF The 114 feature: switch for frequency ranges well into the UHF spectrum. A typical RF application for the Centigrid relay is in handheld radio transceivers, All welded construction. wherein the combined features of good RF performance, small size, low Advanced cleaning techniques provide maximum assurance of internal coil power dissipation and high reliability make it a preferred method of cleanliness. Transmit-Receive switching Unique uni-frame design providing high magnetic efficiency and mechanical rigidity.
