Series 712 DPDT Non-Latching Commercial Electromechanical Relay COMMERCIAL TO-5 RELAYS DPDT SERIES 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 Advanced cleaning techniques provide maximum assurance of internal DESCRIPTION cleanliness. The TO-5 relay, originally conceived and developed by Teledyne, has Precious metal alloy contact material with gold plating assures excellent become one of the industry standards for low-level switching from dry circuit high current and dry circuit switching capabilities. to 1 ampere. Designed for high-density PC board mounting, the Series 712 relays are some of the most versatile ultraminiature relays available The Series 712D relay has an internal discrete silicon diode for coil because of their small size and low coil power dissipation. transient suppression. The hybrid Series 712TN relay has an internal silicon diode and transistor driver. The integrated packaging of the relay The following unique construction features and manufacturing techniques with its associated semiconductor devices greatly reduces PC board floor provide excellent resistance to environmental extremes and overall high space requirements as well as component installation costs. reliability: By virtue of its inherently low intercontact capacitance and contact circuit The 712 feature: losses, the 712 has proven to be excellent ultraminiature RF switch for frequency ranges well into the UHF spectrum. A typical RF application for All welded construction. the TO-5 relay is in handheld radio transceivers, wherein the combined Unique uni-frame design providing high magnetic efficiency and features of good RF performance, small size, low coil power dissipation mechanical rigidity. and high reliability make it a preferred method of Transmit-Receive High force/mass ratios for resistance to shock and vibration. switching Part Numbering System 712 Y M4 - 26 / S Q 1 Q = Solder-Coated Leads Relay Series G = Gold-Plated Leads (RoHS Compliant) 2 R = RoHS Compliant Solder Ground Pin Option (See Appendix) S = 0.187 Leads Pad Option No Suf x = 0.75 Leads (See Appendix) Nominal Coil Voltage (26 = 26.5 V, See Page 2 for more Voltages) ENVIRONMENTAL AND INTERNAL CONSTRUCTION PHYSICAL SPECIFICATIONS Temperature UPPER UNI-FRAME 65C to +125C STATIONARY (Ambient) CONTACT ARMATURE Vibration 10 gs to 500 Hz (General Note I) LOWER STATIONARY Shock 30 gs, CONTACT (General Note I) 6ms half sine MOVING CONTACT Enclosure Hermetically sealed Weight 0.09 oz.
