SO-0420
Open Fram Type Solenoid- Features
- Multi-Voltage Options for Greater Flexibility: Available in 6V, 12V, 24V, and 48V versions, making it compatible with various control power sources or driver modules (DC, PLC, or solenoid valve controllers).
- Low Power Consumption: Operates continuously at only 1.2W under 20°C ambient temperature, featuring energy efficiency and low heat generation — ideal for long-duration operation environments.
- Stable Magnetic Force with Adjustable Output: 100% (Continuous): 1.2W, 219 Ampere-Turns; 50%: 2.4W, 309 Ampere-Turns; 25%: 4.8W, 438 Ampere-Turns; 10%: 12W, 692 Ampere-Turns.
- Supports multi-stage duty cycle control, allowing flexible switching between steady holding force and instant high pull-in force.
- High-Efficiency Coil Design with Excellent Thermal Performance: Coil resistance ranges from 30Ω to 1920Ω (6V→48V), with winding turns increasing accordingly (1095–8760 turns) to ensure a balance between magnetic flux density and minimal temperature rise.
- Compact and High-Efficiency Design: A low-power, high-performance series — ideal for lightweight, automated, and precision mechanical systems.

▍Description
The SO-0420 series is a low-power, high-efficiency electromagnet. At 20°C it delivers 219 AT with only 1.2W in continuous duty, and can switch to 50%/25%/10% intermittent modes to obtain higher peak force (up to 692 AT). Covering 6–48V, the coils—e.g., 6V: 30Ω / 1095 turns; 48V: 1920Ω / 8760 turns—are precisely matched to balance flux and temperature rise. Its compact size, low heat and high reliability make it ideal for long-running automation and precision mechanisms.
