Основные технические параметры
Контактная система

Конфигурация контактов: 3З (three sets of changeover contacts), supporting a resistive load of 5A (220VAC/28VDC), suitable for multi-circuit control scenarios.

Material and Service Life: Silver alloy contacts ensure low contact resistance (≤100mΩ), with an электрический service life of up to 100,000 operations and a mechanical service life of up to 10,000,000 операции.

Insulation Performance: The withstand voltage between the coil and contacts is 1500VAC, and the withstand voltage between open contacts is 500VAC, meeting industrial-grade safety standards.

Характеристики катушки

Диапазон напряжения: Comprehensive specifications for DC (5-220В) and AC (6-380В). Power consumption is 0.9W (для постоянного тока) or 1.8VA (для переменного тока). The pull-in voltage is ≤75% of the rated voltage (для постоянного тока) or ≤80% of the rated voltage (для переменного тока).

Скорость отклика: The operate time is ≤25ms, and the release time is ≤25ms, making it suitable for high-frequency and rapid switching requirements.

Экологическая адаптивность

Рабочая температура: -25℃ to +55℃, with a humidity of ≤95% (при 25℃). It can work stably in high-dust or vibrating environments (double amplitude: 1.0мм, частота: 10-55Гц).

Способы монтажа: Supports plug-in, PCB soldering, and DIN rail mounting. Matching socket models include CZY11A-E (размеры: 72×30×31mm).

Области применения
Промышленная автоматизация

Рекомендации по выбору и установке
Идентификация модели

– Example of a complete model: JZX-22F(Д)/3Z AC220V, где “Д” indicates with a status indicator light, “3З” represents three sets of contacts, и “220 В переменного тока” is the coil voltage.

Характеристики проводки

– Ensure tight contact for plug-in terminals. When soldering to PCB, pay attention to the pin polarity to avoid poor contact caused by cold soldering.

– It is recommended to use the matching CZY11A-E socket, whose screw-type terminals support quick wiring and feature an anti-misinsertion design.

Охрана окружающей среды

– Во влажной среде, a sealed type (such as a model with a cover) должен быть выбран. Regularly check the contact oxidation status, and use contact cleaner for maintenance if necessary.
