CENTIGRID AND TO-5 SERIES 732 COMMERCIAL SENSITIVE TO-5 RELAYS DPDT SERIES RELAY TYPE DESIGNATION 732 DPDT basic relay 732D DPDT relay with internal diode for coil transient suppression 732TN DPDT relay with internal transistor driver and coil transient suppression diode INTERNAL CONSTRUCTION DESCRIPTION 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 for high-density PC board mounting, the 732 relay is one of the most versatile ultraminiature relays available because of its small size and UNI-FRAME low coil power dissipation. UPPER STATIONARY ARMATURE CONTACT The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high LOWER STATIONARY reliability: CONTACT All welded construction. MOVING CONTACT 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 732D relay has an internal discrete silicon diode for coil transient suppression. The hybrid Series 732TN relay has an internal silicon diode and transistor driver. The integrated packaging of the relay with its associated ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS semiconductor devices greatly reduces PC board floor space requirements as well as component installation costs. Storage 65C to +125C Temperature (Ambient) Operating 55C to +85C By virtue of its inherently low intercontact capacitance and contact circuit losses, the 732 relay has proven to be an excellent ultraminiature RF switch Vibration 10 gs to 500 Hz (General Note 1) for frequency ranges well into the UHF spectrum. A typical RF application for the TO-5 relay is in handheld radio transceivers, wherein the combined Shock 30 gs, (General Note 1) 6 msec, half-sine 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).
