SO-1245
Open Frame Type- Features
- High Magnetic Flux Output and Strong Pulling Force: The SO-1245 Series delivers 1200 Ampere-Turns at only 7.5W under continuous operation at 20°C. In 10% intermittent mode, the magnetic force peaks at 3800 AT, providing exceptional instantaneous attraction and powerful holding capability.
- Multi-Level Duty Cycle Control: Supports 100% continuous mode and 50% / 25% / 10% intermittent modes, allowing flexible adjustment of magnetic force and heat balance according to application requirements — ensuring both long-term stability and high peak performance.
- Multiple Voltage Options (6V / 12V / 24V / 48V): Compatible with various DC power supplies and PLC control systems, making integration into automation control modules convenient and efficient.
- High-Efficiency Coil Design: With resistance values ranging from 30Ω to 1920Ω and 1095 to 8760 turns, the coil achieves high magnetic flux density with excellent heat dissipation, extending overall component lifespan.
- Durable Construction and Long-Life Design: Built with a high-permeability iron core and heat-resistant insulation materials, the SO-1245 offers vibration resistance, dust protection, and superior durability — ideal for high-frequency actuation or continuous-duty environments.
Application
The SO-1245 Series Solenoid is suitable for a wide range of industrial, control, and commercial equipment, such as:
