RSE500412 is a MIL-PRF-12883 compliant relay socket manufactured by Amphenol PCD for use in military and commercial applications. The socket features a polyetherimide module body with silicone rubber grommet and stainless steel contact retainers, designed to accommodate various relay configurations ranging from 2 to 25 amp operations. It operates reliably over a temperature range of -65°C to 125°C with an insulation resistance of 1000 megaohms minimum and dielectric withstanding voltage of 2500 VRMS at sea level. The socket contacts are copper alloy with hard gold plating per SAE-AMS 2422, ensuring superior electrical performance and corrosion resistance. RSE500412 is commonly used in military airborne, ground, and shipboard equipment where reliable relay switching and high environmental durability are critical requirements.
