The ES310E1AD is a 3PDT electromagnetic relay built to MIL-PRF-83536, designed for severe-condition applications in aerospace, rail, and ground vehicle systems. It features a hermetically sealed, non-corrosive enclosure and a balanced force design for extended contact life. The relay measures 20.6 mm x 20.6 mm x 16.3 mm and weighs 28.2 grams maximum. It operates with a 28 Vdc coil, has a maximum contact current rating of 10 A, and supports switching voltages up to 115 Vac and 200 Vac. Contact switching is rated for up to 400,000 mechanical cycles. The device operates across a temperature range of -70°C to +125°C, with a maximum coil transient suppression of -42 Vdc. It meets shock and vibration standards specified for mounting codes, with hermetic sealing at 1×10⁻⁸ atm·cm³/s.
