The D31A7100 is a dual in-line reed relay featuring one normally open contact designed for 24V nominal input operation. It incorporates a rhodium contact material with a coil resistance of 2150 O (±10% at 20°C) and supports a maximum switching power of 10 W with a maximum switching current of 500 mA at 100 V peak. The relay demonstrates fast switching performance with an operate time of 1 ms (including bounces) and a release time of 50 µs without a suppression diode, while maintaining an insulation resistance of 10¹° O and a contact resistance of 150 mO maximum. With a mechanical life expectancy of 1×10? operations and an electrical life expectancy of 1×107 operations at 50 V and 100 mA, this relay is well-suited for industrial control applications, automation systems, and switching circuits requiring reliable, compact switching solutions.
