The ORD221 is a small single-contact reed switch designed for general control of medium-level loads less than 100 V. The contacts are sealed within the glass tube with inert gas to maintain contact reliability.
ORD221 is a miniature single‑contact reed switch designed for general control of medium‑level loads less than 100 V. The contacts are hermetically sealed within a glass tube filled with inert gas, providing quick response, compact size, corrosion resistance and long life. It can be used as a proximity switch when a permanent magnet is installed.
The datasheet lists electrical characteristics (pull‑in/drop‑out voltages, contact resistance, breakdown voltage, insulation resistance, capacitance), mechanical characteristics (lead tensile strength, temperature range, shock and vibration test results), operating characteristics (operate, bounce and release times, resonant frequency) and life‑expectancy data under various load conditions. Typical applications include automotive electronics, control equipment, communication gear, measurement devices and household appliances.
