2PCS Mini Push Pull Linear Solenoid Electromagnet 5mm Stroke Open Frame
These compact open-frame solenoids support bi-directional motion with a 5 mm stroke, suitable for small actuators and compact control modules. The model variants include a DC 12V option delivering about 4A with a 5Ω coil, and a 3–5V variant rated around 5A with 0.6Ω resistance. The frames measure roughly 21 x 15 x 13 mm, making them easy to integrate in tight spaces. Cable length is 19 cm, aiding flexible wiring in compact enclosures. Applications include latching mechanisms, valve actuation, and small locks.
2PCS Mini Push Pull Linear Solenoid Electromagnet 5mm Stroke
This pair mirrors the open-frame design with a 5 mm stroke and dual voltage options. The dual-voltage capability (DC 12V and DC 3–5V) enables flexibility in control electronics, while the compact 21 x 15 x 13 mm form factor supports installation in tight spaces. Like other micro solenoids, these are best for instantaneous actuation rather than continuous hold, and heat buildup should be monitored in prolonged operations.
TOMSHIELE DC12V 2A Push Pull Solenoid
Designed for home appliance control and automotive contexts, this 12V push-pull solenoid offers a sustained 65 N push-pull force with a 20 mm stroke. The device emphasizes straightforward installation with M3 threading and a mounting hole pattern. Its operation is described as polarity-agnostic within the rated voltage—an important convenience for high-volume control systems. Suitable for applications requiring a moderate stroke and reliable actuation in compact spaces.
4Pcs DC 12V Micro Push Pull Solenoid
This kit packs four miniature solenoids rated at 12V, with a typical power around 5.5W per unit and a low-stall current that supports compact drive electronics. The 4 mm stroke and 26 ohm coil resistance indicate emphasis on quick, short-range actuation. The product notes caution about heat generation; long continuous operation is not recommended. These are well-suited for multi-channel valve control or compact locking mechanisms in consumer electronics and small appliances.
5PCS DC 12V Mini Push Pull Type Solenoid Actuator
Five compact solenoids at 12V offer an economical option for projects requiring multiple actuators or distributed control. A 4 mm stroke and approximately 2.5W power per unit indicate efficient, quick actuation suitable for small-scale automation, micro-valve control, or educational kits. The metal construction provides durability, though the same heat cautions apply for extended hold times.
2PCS Mini Push Pull Solenoid DC12V 2A 10mm Stroke
This pair features a longer 10 mm stroke and a 12V supply with about 2A current draw, yielding a robust push-pull range for medium-length actuation. The DS-P0630L-05 designation helps with compatibility checks in assemblies that require a specific stroke. It is suitable for medium-duty automation tasks and as a replacement option in existing two-way solenoid actuators.
Buying Guide: Key Purchase Considerations
- Voltage and current compatibility: Two-way solenoids are commonly available at 5V, 12V, or 24V. Ensure your controller can supply the required current without overheating the coil.
- Stroke and force: Choose a stroke length that matches your mechanical travel needs. Higher force is not always better if it causes excessive inertia or power draw.
- Type: Push-pull (two-way) solenoids can push and pull a rod in sequence. Open-frame designs dissipate heat quickly but may require additional shielding in sensitive environments.
- Duty cycle and heat management: Many micro solenoids are not designed for long continuous operation. Plan for short actuation bursts with adequate cooling or duty cycling.
- Mounting and interface: Check thread sizes (e.g., M3), mounting holes, and overall dimensions to ensure compatibility with your device housing or control box.
- Electrical polarity: Some models are polarity-insensitive, simplifying wiring in multi-actuator systems. Others require precise wiring to avoid unintended operation.
- Durability and environmental considerations: Material quality, protection ratings, and operating temperatures affect longevity in harsh or dusty environments.
- Cost and quantity: For projects needing multiple actuators, consider bulk packs or modular kits that minimize wiring complexity and synchronization issues.
- Integration with control systems: Verify compatibility with microcontrollers, PLCs, or relay boards. Look for modules that support PWM or discrete switching for precise control.
- Matching the stroke, force, and voltage to your application ensures reliable actuation without overloading your power supply.
- Open-frame solenoids are easier to mount but may require careful heat management and enclosure design.
- Two-way operation is beneficial for simple latching or bi-directional control where compact form factors are essential.
- When using multiple actuators, plan wiring paths and safety clearances to prevent electrical interference or overheating.
In summary, two-way solenoid actuators provide versatile, compact solutions for linear actuation tasks across consumer electronics, appliances, and automation projects. Selecting the right model involves balancing stroke, force, voltage, and duty cycle with your mechanical design and control capabilities.
