SK-1240
Keep Type- Features
- High Magnetic Flux Output and Strong Medium-Sized Holding Force: The SK-1240 Series features a high-permeability core and optimized coil design, delivering up to 2160 Ampere-Turns in 10% intermittent mode, and maintaining a stable 683 AT in continuous operation, offering consistent push-pull strength and long-duration holding performance.
- High Efficiency and Low Power Consumption: With only 6W coil power under continuous duty, it supports long-term energized operation, effectively minimizing heat buildup and energy usage — ideal for automation and industrial control applications.
- Multiple Duty Cycle Modes: Supports 100%, 50%, 25%, and 10% duty cycle settings, allowing users to switch between continuous holding or high-power intermittent operation as needed.
- Multiple Voltage Versions (6V / 12V / 24V / 48V): Covers standard DC voltage options for easy integration with PLC systems, automation machinery, and other DC power-driven systems.
- Heat-Resistant and Reliable Structure: Constructed with high-temperature enameled copper wire and reinforced insulation layers, ensuring superior magnetic conductivity, long-term stability, and operational safety.
- Compact Size and Flexible Installation: Medium-sized structure offers both high magnetic force and easy integration, suitable for diverse production lines and modular installation environments.
