OPEN FRAME TYPE
SO-0730
Open Frame Type- Features
- High Magnetic Force Output and Stable Performance: The SO-0730 Series features powerful magnetic flux capability, operating at only 2.2W under continuous use at 20°C to deliver 358 Ampere-Turns. In intermittent mode (10% duty cycle), output increases to 22W / 1134 AT, achieving both stable holding force and strong instantaneous actuation performance.
- Multi-Voltage Design: Available in 6V, 12V, 24V, and 48V versions to meet various application and control system integration requirements.
- Excellent Thermal Management: With coil resistance ranging from 16.4Ω to 1047Ω and winding turns between 979 and 7809, it maintains high magnetic flux density while effectively controlling temperature rise.
- Supports Continuous and Intermittent Operation: Compatible with multiple duty cycle modes: 100% (Continuous): 2.2W / 358AT (long-duration holding); 50% (Intermittent): 4.4W / 507AT; 25%: 8.8W / 716AT; 10%: 22W / 1134AT (max. ON time 3 sec); Allows flexible switching between steady magnetic holding and high peak pull-in force according to operational needs.
- Compact and Highly Reliable Structure: Constructed with a high-permeability core and enhanced insulation design, providing low power consumption, excellent heat resistance, and long service life — ideal for high-frequency operation environments.
Application

▍Description
Engineered with high-permeability materials and precision winding, the SO-0730 series delivers 358 AT at 2.2W in continuous duty, and—when switched to 50% / 25% / 10% modes— operates at 4.4 / 8.8 / 22W with peak force up to 1134 AT. Covering 6–48V, its carefully matched coil parameters maintain flux density while controlling temperature rise, making it ideal for automation, access, and precision-control applications.
