SO-1240
Open Frame Type- Features
- High Magnetic Force Output and Stable Performance: The SO-1240 Series utilizes high-permeability silicon steel laminations and precision coil winding technology. It delivers 680 Ampere-Turns with only 4.5W power consumption under continuous operation at 20°C, and up to 2154 AT in 10% intermittent mode — providing both powerful instantaneous attraction and stable holding force.
- Multi-Level Duty Cycle Control: Supports 100% continuous mode as well as 50%, 25%, and 10% intermittent modes. Magnetic output and thermal balance can be flexibly adjusted according to application requirements, accommodating both long-duration operation and short-term high-power actuation.
- Multiple Voltage Versions (6V / 12V / 24V / 48V): Covers common DC voltage ranges, suitable for integration with PLC control systems, industrial drive units, and general-purpose power modules.
- High-Efficiency Coil Structure: With coil resistance ranging from 8Ω to 512Ω and winding turns from 907 to 7253, it achieves high magnetic flux density with low temperature rise, ensuring stable performance and extended service life.
- Rugged and Reliable Construction: Built with high-temperature insulation materials and reinforced frame design, offering vibration resistance, dust protection, and long operational life — ideal for industrial-grade continuous or high-frequency operation environments.
Application
The SO-1240 Series Solenoid is designed for a wide range of automation and control applications, including:
• Industrial automation equipment: solenoid valve control, pneumatic and hydraulic valve actuation modules.
• Mechanical fixtures and positioning devices: adsorption, holding, and release mechanisms for automated assembly lines.
• Security and access control systems: electronic door locks, magnetic latches, and safety release mechanisms.
• Automation control modules: PLC-driven actuator outputs, magnetic brakes, and holding systems.
• Commercial equipment: vending machines, ticket dispensers, coin return, and ejector mechanisms.
• Home appliances and fluid control: coffee machine valve assemblies, water dispensing systems, and electronically controlled valves.
• Medical and testing instruments: miniature actuators, clamping modules, and sample positioning or release systems.
