5503-24-1 is a high voltage reed relay from the 5500 Series, designed for instrumentation, industrial process controls, and general purpose requirements. It features a 24 VDC nominal coil voltage with 575O coil resistance, 1 Form A (normally open) contact configuration, and a maximum switching voltage of 7500V DC/Peak AC. The relay offers high dielectric strength of 10,000 volts isolation across contacts, hermetically sealed tungsten contacts for long life, and a standard magnetic shield. With a contact rating of 50 watts, 3.0A maximum switching current, and 5.0A carry current, it provides reliable performance for demanding applications. Common applications include medical and hipot test instruments, cable test equipment, and other high voltage testing scenarios.
