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, low coil power dissipation make the TO-5 relay one of the most versatile ultraminiature relays available. 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 411D and 411DD Series utilizes internal discrete silicon diodes for coil suppression and polarity reversal protection. The hybrid 411T features an internal silicon suppression diode and transistor driver. This hybrid package reduces PC board floor space by reducing the number of external components needed to drive the relay. 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 T-R switching (see Figure 1). 35 SERIES 411 GENERAL ELECTRICAL SPECIFICATIONS (-65°C to +125°C unless otherwise noted) (Notes 2 & 8) Contact Arrangement Rated Duty Contact Resistance Contact Load Rating (DC) (See Fig. 2 for other DC resistive voltage/current ratings) 1 Form C (SPDT) Continuous 0.1 ohm max. before life; 0.2 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 Contact Load Ratings (AC) Resistive: 250 mA/115VAC, 60 and 400Hz (Case not grounded) 100 mA/115VAC, 60 and 400Hz (Case grounded) Contact Life Ratings 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 Contact Overload Rating 2A/28VDC Resistive (100 cycles min.)
