Product Description:
The 400325 and 400425 series represent high-performance, versatile solenoid valve replacement coils that are engineered for reliability and longevity in challenging industrial settings. Featuring an epoxy-molded construction, these coils deliver superior protection against moisture, dust, and chemical corrosion, which guarantees consistent and stable electrical performance over time.
Designed to operate at 100% continuous duty (ED), these coils incorporate an F or H class insulation system, enabling them to endure elevated operating temperatures and frequent cycling without compromising their functionality. They are built to function smoothly across a broad voltage tolerance range, from +10% to -15% of the nominal voltage, and come in a wide array of standard AC and DC voltages that cater to various global power supply requirements.
The series includes specific models such as the 400325 and 400425, which support voltages including AC24V, AC110V, AC115V, AC220V, and DC24V. Depending on the configuration, these coils come equipped with either standard spade plug connectors or flying leads. This design allows them to serve as direct drop-in replacements during maintenance and repairs, effectively restoring the original valve response times and minimizing system downtime.
Features:
The product features an epoxy molded construction that offers strong encapsulation. This design effectively shields the winding from exposure to moisture, dust, and industrial chemicals, ensuring long-term durability and reliability.
It boasts a high ingress protection rating of IP65 or above, depending on the specific assembly. This rating guarantees dependable operation even in challenging and harsh environmental conditions.
Equipped with Class F / H insulation, the coil demonstrates excellent thermal endurance. This high thermal resistance enables it to function reliably at elevated ambient temperatures without degradation.
With a 100% continuous duty rating, the device is engineered to remain energized indefinitely. This ensures it can operate continuously without the risk of overheating or failure.
The design incorporates a wide voltage tolerance, capable of handling fluctuations ranging from +10% to -15% relative to the nominal voltage. This flexibility makes it suitable for varied electrical environments.
It offers multiple voltage options, supporting a broad range of control systems including AC voltages of 24V, 110V, 115V, and 220V, as well as DC voltage of 24V.
For ease of wiring and replacement, the product includes standardized connections. These consist of standard spade plug connectors conforming to DIN 43650 or alternatively, flying leads.
Lastly, its robust mechanical design provides excellent vibration resistance. This ensures stable and reliable performance even in environments subject to high levels of vibration.
