JF-1039B DC12V 25N 10MM Push-pull Permeable Electromagnet Lock
JF-1039B DC12V 25N 10MM Push-pull Permeable Electromagnet Lock
JF-1039B DC12V 25N 10MM Push-pull Permeable Electromagnet Lock
The JF-1039B is a DC12V push-pull permeable electromagnet lock engineered for precise electromagnetic actuation in access control and security systems. Professional installers, automation engineers, and security system integrators rely on this electromagnet for its reliable 25N holding force and bidirectional push-pull capability in confined spaces. This solenoid lock solves the critical challenge of achieving compact, high-force electromagnetic locking in applications where space constraints and dual-direction control are essential requirements.
Product Overview
The JF-1039B operates on the principle of electromagnetic induction, where DC current flowing through its copper coil generates a magnetic field that attracts the permeable iron plunger. This design enables both push and pull actuation from a single compact 10mm stroke mechanism, making it ideal for applications requiring bidirectional force control. The permeable core construction ensures rapid magnetic field concentration and efficient energy conversion, delivering consistent 25N force output while minimizing power consumption and heat generation during extended operation cycles.
This electromagnet lock features a robust solenoid construction with sealed coil windings that provide protection against dust and moisture ingress in industrial environments. The 10mm plunger stroke allows for precise positioning in locking mechanisms, while the push-pull configuration eliminates the need for separate push and pull solenoids, reducing system complexity and installation footprint. The DC12V specification makes it compatible with standard industrial power supplies and battery-backed security systems, ensuring reliable operation across diverse installation scenarios.

How to Use
Begin installation by identifying the mounting location with sufficient clearance for the 10mm plunger stroke in both push and pull directions. Secure the electromagnet using the provided mounting bracket, ensuring the plunger aligns precisely with the locking mechanism's engagement point. Connect the positive DC12V supply wire to the solenoid's positive terminal and ground the negative wire to complete the circuit. Install a protection diode across the coil terminals to suppress back-EMF voltage spikes during deactivation, preventing damage to control circuitry and extending solenoid lifespan.
For push-pull operation, integrate the solenoid with a mechanical linkage or cam system that converts linear plunger motion into the required locking and unlocking actions. Connect the control signal from your access control system, timer, or microcontroller to the solenoid circuit through a relay or solid-state switch rated for the electromagnet's current draw. Test the actuation sequence under no-load conditions first, verifying smooth push-pull movement and audible click confirmation of magnetic engagement. Adjust mechanical linkage tension as needed to ensure the plunger returns fully to its neutral position when power is removed, preventing mechanical binding or incomplete locking.
Frequently Asked Questions
What is the difference between push-pull and standard solenoids?
Standard solenoids provide unidirectional force in a single direction, requiring separate units for push and pull actions. The JF-1039B push-pull design integrates both functions in one compact electromagnet, with the plunger moving outward when energized and retracting when de-energized. This reduces component count, wiring complexity, and installation space while maintaining 25N force in both directions, making it ideal for applications requiring bidirectional locking control.
Can the JF-1039B operate continuously without overheating?
The JF-1039B is designed for continuous duty cycle operation with optimized coil resistance that balances holding force with thermal management. However, continuous energization generates heat in the copper windings. For extended operation, ensure adequate ventilation around the solenoid, monitor coil temperature with thermal sensors if operating in enclosed spaces, and consider duty cycle control using PWM signals to reduce average power consumption. Most industrial applications use intermittent actuation rather than continuous energization, which significantly reduces thermal stress.
What control circuit is required for the JF-1039B?
The JF-1039B requires a DC12V power supply capable of delivering the solenoid's peak current draw during actuation. Connect the circuit through a relay, MOSFET, or solid-state switch controlled by your access control system, microcontroller, or timer. Always install a protection diode (1N4007 or equivalent) in reverse bias across the solenoid terminals to suppress inductive back-EMF voltage spikes that occur when the coil is de-energized. This prevents voltage transients from damaging sensitive control electronics and extends solenoid operational life.
Is the JF-1039B suitable for outdoor installations?
While the JF-1039B features sealed coil construction providing dust protection, it is primarily designed for indoor industrial environments. For outdoor applications exposed to rain, UV radiation, and temperature extremes, install the solenoid within a weatherproof enclosure with drainage provisions. Apply silicone sealant around terminal connections, use stainless steel mounting hardware to prevent corrosion, and consider conformal coating on control circuitry. Test the installation during seasonal weather variations to ensure reliable operation across temperature ranges.
