JF-1040B Push-Pull DC Solenoid – 10mm Stroke, 200g 25N Force (6V/12V 2A/24V 1A Optional)

Description

The JF-1040B is an open-frame push-pull DC solenoid designed for short-stroke linear actuation requiring a solid force output in a compact package. It delivers approximately 25N (≈2.5kg) of holding force, making it suitable for vending machine mechanisms, office equipment, electronic locks, and light automation devices . The solenoid uses a spring-return plunger: when the coil is energized, the plunger moves to perform work; when power is removed, the internal spring returns it to the rest position . The open-frame construction features a low-carbon steel frame and copper coil, with M3 mounting holes for secure installation. Available in 12V and 24V coil variants, the JF-1040B accommodates different DC power architectures.

Important Note on Specifications: Listings for the JF-1040B show significant inconsistencies across sources. The 12V variant is consistently listed at 0.4A by multiple independent suppliers , while the 24V variant is also listed at 400mA by several sources . Notably, the stroke is reported as 10mm by some suppliers and 15mm by others . Buyers should verify the exact stroke and current specifications of their specific unit with the supplier before finalizing mechanical and driver designs. The solenoid is designed for intermittent operation; one supplier explicitly states a maximum continuous energization time of 1 minute .

Features

• 25N Holding Force: Provides solid actuation force for latching, locking, and dispensing tasks in light commercial and automation equipment .

• Push-Pull Operation with Spring Return: Plunger performs work when energized and automatically resets via internal spring when power is removed, simplifying mechanical design .

• Low-Carbon Steel Frame: Good magnetism with minimal flux leakage and low residual magnetism .

• Dual Voltage Options: Available in 12V and 24V coil variants, both commonly rated at 0.4A .

• Threaded Plunger Shank: The plunger shank has an M4 threaded hole, allowing attachment of a screw or stud to convert the solenoid for push or pull operation .

• M3 Mounting Holes: Integrated mounting points with approximately 19.7 × 18.1mm spacing simplify secure attachment .

• Intermittent Duty Design: Maximum continuous energization time of 1 minute; not intended for sustained holding without current reduction .

• Rated for 1 Million Cycles: Life rating of over one million cycles under load .
