JMX-94F-A-Z Latching Relay 12VDC 80A/220V
The JMX-94F-A-Z Latching Relay 12VDC 80A/220V is a high-current magnet latching relay designed for reliable switching in power control circuits. It uses a 12VDC coil and supports a heavy contact load up to 80A at 220VAC, making it suitable for applications that require strong load handling with stable switching performance. According to the PDF, the JMX-94F series is built with high sensitivity, high reliability, good anti-shock performance, and good anti-vibration performance.
This relay is a Single Coil Latching type, which means it can hold its contact position magnetically after receiving a control pulse. It does not need continuous coil power to remain in the set or reset state, helping reduce power consumption and heat during operation. The relay is pulse operated and designed for pulse control, with an ideal pulse duration of 50ms to 100ms for stable operation. The PDF also notes that latching relay coils should not be pulsed incorrectly, and the pulse width should be sufficient to ensure proper magnetic positioning.
The JMX-94F-A-Z model uses a 1A SPST-NO contact arrangement, with a dust cover enclosure and silver cadmium oxide contact material for heavy-load switching. The relay has an approximate operate time of 60ms and release/reset time of 20ms, allowing controlled switching in electrical power systems, meters, industrial control panels, and energy management circuits. With insulation resistance of 1000MΩ minimum, dielectric strength up to 4000VAC between contact and coil, and an operating temperature range from -25°C to +70°C, it is suitable for demanding control environments.
