The W171DIP-4 is a single-pole, single-throw, normally open (SPST-NO) reed relay designed for fast, low-power switching. It operates with a nominal coil voltage of 12VDC and a coil resistance of 1000 ohms, consuming 144mW of nominal power. This relay is capable of switching up to 0.5A at a maximum of 100VDC, features a maximum operate time of 1.0ms, and has a high dielectric strength of 1500VDC between the coil and contacts. Housed in an industry-standard DIP package that can withstand immersion cleaning, it is ideal for use in telecommunications, security systems, and other general-purpose circuits.
