TELEDYNE RELAYS CENTIGRID® ESTABLISHED RELIABILITY RELAY SERIES 114 DPDT SERIES DESIGNATION 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 INTERNAL CONSTRUCTION DESCRIPTION The 114 series Centigrid® Relay is an ultraminiature, hermetically sealed, armature relay. Its low profile height (.275") and .100" grid spaced terminals, which precludes the need for spreader pads, make it ideal for applications where extreme packaging density and/or close PC board spacing are required. UNI-FRAME UPPER STATIONARY CONTACT ARMATURE LOWER STATIONARY CONTACT MOVING CONTACT The basic design and internal construction are similar to the Teledyne standard DPDT TO-5 relay (412 Series). The following unique construction features and manufacturing techniques provide overall high reliability and excellent resistance to environmental extremes: • • • • • 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 114D and 114DD 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 0.09 oz (2.55 gms.) max. By virtue of its inherently low intercontact capacitance and contact circuit losses, the 114 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 114 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). 23 SERIES 114 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 ohm max. before life; 0.2 ohm 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.)
