TELEDYNE RELAYS CENTIGRID® ESTABLISHED RELIABILITY RELAY SERIES 134 SENSITIVE DPDT SERIES DESIGNATION RELAY TYPE 134 DPDT basic relay 134D DPDT relay with internal diode for coil transient suppression 134DD DPDT relay with internal diodes for coil transient suppression and polarity reversal protection INTERNAL CONSTRUCTION DESCRIPTION The sensitive Centigrid® relay retains the same features as the standard Centigrid® with only a minimal increase in profile height (.375 in.). It provides a .100 in. grid spaced terminal pattern which precludes the need for spreader pads and, together with the low profile, is ideal for applications where high packaging density is important. UPPER STATIONARY CONTACT UNI-FRAME The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high reliability: ARMATURE • • • • • LOWER STATIONARY CONTACT MOVING CONTACT 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 134D and 134DD Series utilizes internal discrete silicon diodes for coil suppression and polarity reversal protection. ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS Temperature (Ambient) -65°C to + 125°C Vibration 30 g’s to 3000 Hz (Note 1) Shock 75 g’s for 6 msec. (Note 1) half-sine Acceleration 50 g’s (Note 1) Enclosure All welded, hermetically sealed Weight 0.15 oz (4.3 gms.) max. The sensitive Centigrid® relay features exceptionally high coil resistance thus providing for extremely low operating power (200 mw typical). The advantages of reduced heat dissipation and power supply demands are obvious. By virtue of its inherently low intercontact capacitance and contact circuit losses, the 134 relay has shown itself to be an excellent ultraminiature RF switch for frequency ranges well into the UHF spectrum. A typical RF application for the Centigrid® relay is in hand held radio transceivers, wherein the combined features of good RF performance, small size, low coil power dissipation and high reliability make it a preferred method of Transmit-Receive switching (see Figure 1). 29 SERIES 134 GENERAL ELECTRICAL SPECIFICATIONS (-65°C to +125°C unless otherwise noted) (Notes 2 & 7) Contact Arrangement Rated Duty Contact Resistance Contact Load Rating (DC) (See Fig. 2 for other DC resistive voltage/current ratings) 2 Form C (DPDT) Continuous 0.1 ohms max. before life; 0.2 ohms max. after life at 1A/28VDC, (measured 1/8” from header) Resistive: 1 Amp/28VDC Inductive: 200 mA/28VDC (320 mH) Lamp: 100 mA/28VDC Low Level: 10 to 50 µA/10 to 50 mV Resistive: 250 mA/115VAC, 60 and 400Hz (Case not grounded) 100 mA/115VAC, 60 and 400Hz (Case grounded) 10,000,000 cycles (typical) at low level 01,000,000 cycles (typical) at 0.5A/28VDC resistive 00,100,000 cycles min. at all other loads specified above 2A/28VDC Resistive (100 cycles min.)
