Series 411 SPDT Non-Latching Established Reliability / Military Relay ESTABLISHED RELIABILITY MILITARY TO-5 RELAYS SPDT SERIES RELAY TYPE 411 SPDT basic relay 411D SPDT relay with internal diode for coil transient suppression 411DD SPDT relay with polarity reversal protection and coil transient suppression diode 411T SPDT relay with internal transistor driver and coil transient suppression diode Precious metal alloy contact material with gold plating assures excellent DESCRIPTION high current and dry circuit switching capabilities. The TO-5 relay, originally conceived and developed by Teledyne, has become one of the industry standards for low-level switching from dry circuit The Series 411D and 411DD relays have internal discrete silicon diodes to 1 ampere. Designed specifically for high-density PC board mounting, its for coil suppression and polarity reversal protection. The hybrid 411T relay small size and low coil power dissipation make the 411 relay one of the most features an internal silicon suppression diode and transistor driver. This versatile ultraminiature relays available. hybrid package reduces required PC board floor space by reducing the number of external components needed to drive the relay. The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high By virtue of its inherently low intercontact capacitance and contact circuit reliability. losses, the 411 relay has proven to be an excellent ultraminiature RF The 411 feature: switch for frequency ranges well into the UHF spectrum. A typical RF application for the TO-5 relay is in handheld radio transceivers, wherein All welded construction. the combined features of good RF performance, small size, low coil power Unique uni-frame design, providing high magnetic efficiency and dissipation and high reliability make it a preferred method of T-R switching mechanical rigidity. (see Figure 1). High force/mass ratios for resistance to shock and vibration. Advanced cleaning techniques provide maximum assurance of internal cleanliness.
