ESTABLISHED RELIABILITY SERIES CENTIGRID 134 ESTABLISHED RELIABILITY RELAYS SENSITIVE DPDT SERIES RELAY TYPE DESIGNATION 134 DPDT basic relay 134D DPDT relay with internal diode for coil transient suppression DPDT relay with internal diodes for coil transient suppression and polarity 134DD reversal protection INTERNAL CONSTRUCTION DESCRIPTION The 134 sensitive Centigrid relay retains the same features as the 114 standard Centigrid relay with only a minimal increase in profile height (.375 in.). Its .100-inch grid spaced terminals, which preclude the need for spreader UNI-FRAME UPPER pads, and its low profile make the 134 relay ideal for applications where high STATIONARY CONTACT packaging density is important. ARMATURE The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high reliability: All welded construction. Unique uni-frame design providing high magnetic efficiency and mechanical LOWER STATIONARY rigidity. CONTACT MOVING High force/mass ratios for resistance to shock and vibration. CONTACT 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 134D and 134DD have internal discrete silicon diodes for coil suppression and polarity reversal protection. ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS The sensitive 134 Centigrid relay has a high resistance coil, thus requiring Temperature extremely low operating power (200 mw typical). The advantages of reduced 65C to +125C (Ambient) heat dissipation and power supply demands are a plus. Vibration 30 gs to 3000 Hz By virtue of its inherently low intercontact capacitance and contact circuit (General Note 1) losses, the 134 relay has proven to be an excellent ultraminiature RF switch Shock 75 gs, for frequency ranges well into the UHF spectrum. A typical RF application for (General Note 1) 6 msec, half-sine the Centigrid relay is in handheld radio transceivers, wherein the combined Acceleration 50 gs features of good RF performance, small size, low coil power dissipation and high reliability make it a preferred method of Transmit-Receive switching (see Enclosure Hermetically sealed Figure 1).
