OPEN FRAME TYPE
SO-1250
Open Frame Type- Features
- Multiple Voltage Options Available: Offered in 6V, 12V, 24V, and 48V versions for flexible compatibility with various control power systems (DC/AC driver modules, PLCs, and control panels).
- Supports Continuous and Intermittent Operation: 100% Duty Cycle (Continuous Type): can remain energized for long periods without overheating. 50%, 25%, and 10% Duty Cycle (Intermittent Types): allow higher voltage or power for short durations to achieve stronger magnetic force — ideal for instantaneous activation or impact motion applications.
- Proportional Increase of Power and Magnetic Force: During intermittent operation, power scales from 7.5W → 15W → 30W → 75W, corresponding to magnetic force (Ampere-Turns) increasing from 1200 → 1700 → 2400 → 3800, demonstrating the solenoid’s ability to deliver high magnetic flux output within short intervals.
- Excellent Coil Thermal and Wire Design: Each voltage level corresponds to optimized coil turns and resistance (e.g., 6V: 960 turns → 48V: 7680 turns), ensuring balanced efficiency, low temperature rise, and reliable long-term performance.

▍Description
The SO-1250 series electromagnet features high magnetic permeability materials and precision coil winding for stable and powerful performance. At 20°C, it operates efficiently at 7.5W in continuous duty and can switch to intermittent modes (50%, 25%, 10%) for greater instantaneous force. Coil parameters ranging from 6V to 48V are carefully matched for resistance and turns count to maintain magnetic flux density and temperature control. This series combines long-duration holding capability with high-force actuation, ideal for automated valves, locking systems, industrial actuators, and precision control mechanisms.
