HFW4A1196S01 is a Hi-G electromagnetic relay designed for demanding applications requiring high reliability under extreme environmental conditions. The relay features a coil with 600 O ± 10% resistance at +25°C, a nominal voltage of 26.5 VDC, must operate voltage of 13.4 VDC, and must release voltage of 1.5 VDC. It offers a contact rating of 4 Amps at 28 VDC resistive with 100,000 operations life expectancy. The unit is engineered to withstand vibration from 10 CPS to 2000 CPS at 20 g's, shock of 100 g's at ±1 ms duration, and operates over a temperature range of -67°C to +125°C. This relay is well-suited for communication instruments and other applications where rugged performance in harsh environments is essential.
