24VDC Nominal Operating Coil (Standard DC Excitation), Single-Pole Double-Throw (SPDT / 1 Form C), 1A @ 24VDC / 0.5A @ 120VAC Contact Rating, High-Sensitivity Sealed Miniature Comp onent Relay. It incorporates high-purity gold-overlay silver-palladium alloy bifurcated contacts engineered to eliminate dry-circuit surface tracking hazards and deliver absolute micro-signal tracking continuity. Operating with a standard low-profile through-hole terminal pattern layout, it interfaces cleanly with legacy computing mainframes, plant process controllers, and telecommunication circuit boards. This structural design suppresses localized contact bounce and withstands relentless runtime machinery floor vibrations to secure permanent signal phase stability. Housed in a standard plastic-sealed protective insulation shroud envelope. Manufactured by Fujitsu (Takamisawa).
