DC12V 1.2A Push Pull Solenoid, 1.5-20N, 12mm Stroke
Model name 1039B offers a 12 mm stroke with a 1.5–20N push-pull force range. It operates at DC12V with a current draw of 1.2A. Installation uses M4 threaded holes and a Ø3 mounting hole, making it adaptable for compact enclosures. The wiring method does not distinguish polarity, and force can be varied by voltage within the rated range. Best for small, precise actuations in positioning tasks or mini automation where space is limited.
Best for: compact positioners and small assemblies where a variable force is beneficial. Limitations include a relatively narrow stroke for some applications and moderate current draw.
Push Pull Solenoid, 12V, 35mm Stroke
This model features a DC12V solenoid coil with a 35 mm stroke and a sturdy frame-type construction. It delivers a strong push-pull action with a plunger spring return and low-friction performance. All-copper coils provide stable temperature behavior for extended operation. It can produce a 35 mm thread and is suitable for DIY automation projects requiring longer travel and reliable actuation.
Best for: longer-stroke DIY projects and hobby automations where a robust, continuous push-pull cycle is needed. Caution: larger size may require more mounting space and power considerations.
Heschen DC 12V Solenoid, 60N, 20mm Stroke
HS-1564B provides up to 60N of max keep force after removing a shim, with a 20 mm stroke and initial force around 3N. It uses a copper coil for stable operation and open-frame design for easy installation. Rated at DC12V with 3A current. Best for higher-force applications where reliable, linear actuation is essential. Limitation: may require precise mounting and impedance considerations at higher loads.
Best for: projects needing strong hold-force and stable operation in a compact frame. Choose this if higher initial and keep forces are critical for your mechanism.
DC12V 2A Push Pull Solenoid, 35N, 20mm Stroke
Model 1564B offers a broad force range of 3.5–35N with a 20 mm stroke and DC12V operation. It features a robust 125×40×35 mm body and an all-copper coil for reliable heat handling. The wiring is non-polarized within voltage range, and force increases with voltage. Best for automotive and home automation tasks requiring moderate to strong actuation at a moderate footprint.
Caution: ensure your power supply can handle up to 2A peak during activation. Best for: mid-range force needs and projects where space is not severely limited.
Heschen DC 12V Solenoid, 5N, 10mm Stroke
This Heschen model delivers a 5N maximum force with a 10 mm stroke and 12V operation. It has a low initial force of 0.5N and uses a copper coil for stable operation. It is easy to install and suits compact tasks where small movement is required. Best for precise, light-duty actuation in tight spaces. Limitation: lower force means it may not handle heavier loads.
Best for: micro-actuation and lightweight mechanical tasks where quick response and compact size matter. Avoid this if higher push force is required for your mechanism.
Buying Guide
What force range do you need? Compare the push-pull force at the operating voltage. Higher forces demand larger coils and possibly more current.
What stroke length suits your design? Short-stroke units save space; long-stroke solutions enable greater travel per actuation.
What power considerations exist? DC12V is common, but current draw varies widely. Ensure your power supply can handle startup surges.
Do you need non-polarized wiring? Several models allow force adjustment via voltage, while others are polarity-insensitive for simpler wiring.
What mounting and installation constraints apply? Check hole sizes, thread dimensions, and available open-frame or enclosed designs to fit your chassis.
How important is durability and heat tolerance? Copper coils and low-friction components improve longevity in continuous cycles.
FAQ
What is a push-pull solenoid used for?
A push-pull solenoid converts electrical energy into linear motion, enabling quick back-and-forth magnetic actuation in devices like latches, switches, and automation modules.
Can I mix different solenoids in one project?
Yes, but ensure compatible voltage, current, and stroke requirements to prevent uneven actuation or power issues.
Do these solenoids require special wiring?
Most models operate at DC12V with straightforward wiring, some use non-polarized connections for ease of use.
How do I choose the right stroke?
Match the travel distance to the mechanism’s displacement needs. Longer strokes enable bigger linear movement but require more space.
What maintenance is needed?
Keep connections clean, verify mounting stability, and periodically inspect for coil overheating in high-duty cycles.
