JF-1578B Push-Pull DC Solenoid – 10mm Stroke, 5Kg 50N Force (DC12V-6A/24V 5A Optional)

Description

The JF-1578B is a high-force open-frame push-pull DC solenoid designed for demanding linear actuation in access control, automation, vending, and industrial equipment. It delivers a rated holding force of 5kg (≈50N) across a 10mm stroke, making it suitable for electromagnetic locks, sorting mechanisms, robotic end-effectors, and automated door/drawer latches . 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 copper coil for thermal stability and conductivity, housed in a compact metal frame measuring approximately 105 × 52 × 45mm . Available in multiple voltage variants (including 12V and 24V), the JF-1578B accommodates different DC power architectures.

Critical Note on Specifications: Search results for the JF-1578B show significant inconsistencies across sources. One supplier lists 8A rated current with 5kg force and 15mm stroke for a 12V variant , while an Amazon listing specifies 8A, 192W, 50N force, and 15mm stroke for a 24V unit . Other sources consistently report 5kg force with 10mm stroke for the JF-1578B in various voltages (6V, 12V, 24V) . The product title you provided states 6A for 12V and 5A for 24V, which differs from the 8A figure found in some listings. Buyers must verify the exact voltage, current, force, and stroke specifications with their specific supplier before designing drivers or mechanical linkages. The solenoid is intended for intermittent operation only—one source recommends a maximum working time of 2 seconds per activation due to high current draw .

Features

• High Holding Force: Rated at 5kg (≈50N), suitable for electromagnetic locks, latches, and mechanisms requiring substantial holding power .
