Description
The JF-1670DL (also listed as JF-S1670DL) is an open-frame push-pull DC solenoid designed for short-stroke locking and actuation in access control, vending, and automation equipment. It delivers a rated holding force of 40N (approximately 4kg retracting force, with initial force around 1kg) across a 10mm stroke, making it suitable for door locks, safe box latches, vending machine mechanisms, and office equipment . The solenoid uses a spring-return plunger: when the coil is energized, the plunger retracts or extends to perform work; when power is removed, the internal spring returns it to the rest position . The open-frame construction features a metal housing with M4 threaded mounting holes, measuring approximately 70 × 40 × 26mm .
Critical Note on Specifications: Search results for this model show significant inconsistencies in current ratings across different sources, and notably, most results reference the variant JF-S1670DL rather than the exact “JF-1670DL” in your title. The 12V variant is reported at 3.38A by one supplier , 3A by another , 2.4A by a third , and even 0.4A by a fourth . The product title you provided states 2A for 12V and 1A for 24V, which differs from most found figures. The 24V variant is less documented, with one listing indicating 1.5A . Buyers must measure the actual current draw of their specific unit before finalizing driver and power supply designs. The solenoid is intended for intermittent operation only—one supplier explicitly warns it “cannot be energized for a long time” .
Features
-
40N Force with 10mm Stroke: Provides moderate holding force for door locks, safe boxes, vending machines, and office equipment .
-
