Series 722 DPDT Magnetic-Latching Commercial Relay TO-5 MAGNETIC-LATCHING COMMERCIAL RELAYS DPDT SERIES RELAY TYPE 722 DPDT basic DESCRIPTION The Series 722 magnetic-latching relays are ideally suited for applications The magnetic-latching TO-5 relay, originally conceived and developed by where coil power dissipation must be minimized. The relays can be Teledyne, has become one of the industry standards for low-level switching operated with a short duration pulse and after the contacts have from dry circuit to 1 ampere. Designed for high-density PC board mounting, transferred, no external coil power is required. The magnetic-latching the 722 relay has become one of the most versatile ultraminiature relays feature of the Series 722 provides a memory capability, since the relays available because of its small size and low coil power dissipation. will not reset upon removal of coil power. Unique construction features and manufacturing techniques provide By virtue of its inherently low intercontact capacitance and contact circuit excellent resistance to environmental extremes and overall high reliability. losses, the 722 relay has proven to be an excellent ultraminiature RF switch for frequency ranges well into the UHF spectrum. A typical RF The 722 feature: application for the TO-5 relay is in handheld radio transceivers, wherein the combined features of good RF performance, small size, low coil power All welded construction. dissipation and high reliability make it a preferred method of Transmitter- Unique uni-frame design providing high magnetic efficiency and Receive switching (see Figure 1). 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.
