TELEDYNE RELAYS SERIES 712 COMMERCIAL/INDUSTRIAL TO-5 RELAYS DPDT SERIES DESIGNATION RELAY TYPE 712 DPDT basic relay 712D DPDT relay with internal diode for coil transient suppression 712TN DPDT relay with internal transistor driver and coil transient suppression diode DESCRIPTION INTERNAL CONSTRUCTION The TO-5 relay, originally conceived and developed by Teledyne, has become one of the industry standards for low level switching from dry circuit to 1 ampere. Designed expressly for high density PC Board mounting, its small size and low coil power dissipation make the TO-5 relay one of the most versatile ultraminiature relays available. UPPER STATIONARY CONTACT UNI-FRAME ARMATURE LOWER STATIONARY CONTACT MOVING CONTACT 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 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 712D Series utilizes an internal discrete silicon diode, for coil transient protection. The hybrid 712TN Series features an internal silicon diode and transistor driver. The integrated packaging of the relay with its associated semiconductor devices greatly reduces PC Board floor space requirements as well as component installation costs. ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS Temperature (Ambient) -55°C to +85°C Vibration 10 g’s to 500 Hz (Note 3) Shock 30 g’s for 6 msec. (Note 3) half-sine Enclosure Hermetically sealed Weight 0.09 oz (2.6 gms.) max. By virtue of its inherently low intercontact capacitance and contact circuit losses, the TO-5 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 TO-5 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 TransmitReceive switching (see Figure 1). 98 SERIES 712 GENERAL ELECTRICAL SPECIFICATIONS (@ 25°C)) (Notes 1 & 2) Contact Arrangement Rated Duty Contact Resistance (Note 4) Contact Load Rating (DC) (See Fig. 2 for other DC resistive voltage/current ratings) 2 Form C (DPDT) Continuous 0.15 ohm max. before life; 0.25 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.)
