Product Description:
The 400325 and 400425 series represent high-performance, versatile solenoid valve replacement coils that are engineered for reliability and longevity in tough industrial settings. Featuring an epoxy-molded design, these coils offer exceptional protection against moisture, dust, and chemical corrosion, which guarantees consistent and stable electrical performance over time.
These coils are designed to handle 100% continuous duty (ED) and incorporate an insulation system rated as class F or H. This allows them to endure high operating temperatures and frequent cycling without compromising their functionality. Additionally, the coils can operate effectively within a broad voltage tolerance of +10% to -15% relative to the nominal voltage, making them adaptable to varying power conditions.
Available in a wide range of standard AC and DC voltages to accommodate global power requirements, the series includes specific models such as the 400325 and 400425. They cover common voltages including AC 24V, AC 110V, AC 115V, AC 220V, and DC 24V. Depending on the configuration, these coils come equipped with either standard spade plug connectors or flying leads, facilitating straightforward installation as direct replacements.
Designed as a direct drop-in solution, these replacement coils help restore the original response times of solenoid valves, thereby minimizing system downtime and streamlining maintenance or repair processes in industrial operations.
Features:
The epoxy molded construction offers a durable encapsulation that effectively shields the winding from moisture, dust, and various industrial chemicals. This robust design ensures long-lasting protection and reliability.
With a high ingress protection rating of IP65 or above, depending on the specific assembly, the device guarantees dependable operation even in challenging and harsh environments. This level of protection prevents the ingress of dust and water.
The coil is equipped with Class F or Class H insulation, providing excellent thermal resistance. This feature allows it to function reliably at elevated ambient temperatures without compromising performance.
Designed for continuous operation, the coil carries a 100% duty rating. It can remain energized indefinitely without the risk of overheating or failure, ensuring consistent and uninterrupted service.
Engineered to tolerate voltage variations, the coil maintains proper functionality with fluctuations ranging from +10% to -15% relative to the nominal voltage. This wide voltage tolerance enhances its adaptability to varying power conditions.
Multiple voltage options are available to support broad compatibility. It can work seamlessly with both AC voltages (24V, 110V, 115V, 220V) and DC voltage (24V) control systems, catering to diverse application requirements.
For ease of installation and replacement, the coil comes with standardized connections. It features standard spade plug connectors conforming to DIN 43650 or flying leads, enabling straightforward wiring.
The coil's robust mechanical design provides excellent resistance to vibration. This ensures steady and stable performance even in environments subject to high levels of vibration.
