Comus International Coto Reed Switches RI-69

The RI-69 Series Dry Reed Switch from Comus International is an ultra-miniature, hermetically sealed switch designed for various applications including relays, sensors, and pulse counters. It features a single-pole, single-throw (SPST) configuration with normally open contacts, and is actuated by either an electromagnet or a permanent magnet. The switch can handle a maximum load of 20W and supports switching voltages up to 200V DC and 140V AC RMS. The device has a life expectancy of at least 10^9 operations under no load conditions and 2 x 10^7 operations under loaded conditions, with a failure rate of less than 2 x 10^-10 and 10^-8, respectively, at a 90% confidence level. It operates effectively within a temperature range of -55¬8C to +75¬8C, with storage capabilities up to +125¬8C. The RI-69 switch is also designed to withstand mechanical shocks and vibrations according to IEC standards, ensuring reliability in demanding environments. With a compact size of 0.39 inches in length and a diameter of 0.071 inches, the RI-69 is suitable for applications where space is limited. The switch's construction includes gold and sputtered ruthenium contact layers, providing enhanced durability and performance.
