❌ Inconsistent Stroke & Force

Off-the-shelf solenoids often fail to deliver repeatable stroke lengths or high-force outputs (e.g., 5N–50N) under variable loads. Result? System downtime and costly recalibrations.

“We wasted 6 weeks troubleshooting a valve system due to solenoid stroke drift.” – Automation Engineer, Germany

❌ High Costs with Limited Customization

European/US suppliers charge 30–50% premiums for custom coil voltages (12V/24V/110V) or IP65-rated enclosures. Lead times? 12–16 weeks.

“We needed a 12V DC solenoid with a 20mm stroke—quoted $120/unit in the US. YIDI delivered at $65.” – Purchasing Manager, Canada

❌ Supply Chain Bottlenecks

Post-pandemic, 80% of buyers report delays from traditional suppliers. YIDI’s advantage: In-house production (100+ employees) + German/Japanese machinery = 4-week lead times.

“Switched to YIDI after a 3-month delay from our US vendor. Never looked back.” – Operations Director, France

Why YIDI?

As a direct manufacturer with 100+ employees and 30% senior technicians, we specialize in linear solenoids with:

• High-Force Outputs: 5N–100N (customizable for heavy-duty applications).
• Precision Stroke Control: ±0.1mm tolerance across 2mm–50mm strokes.
• Rapid Response: 10–50ms actuation time for high-speed systems.
• Durability: IP65/IP67 ratings, -40°C to +120°C operating range.
• OEM/ODM Flexibility: Custom coil voltages (5V–230V), plunger materials (stainless steel/ceramic), and mounting configurations.

Competitive Edge: Unlike generic suppliers, YIDI uses German/Japanese machinery to ensure ±0.01mm manufacturing precision—critical for aerospace and medical devices.

YIDI’s state-of-the-art production line for linear solenoids

“YIDI’s solenoids reduced our valve system failure rate by 40%. Their ±0.1mm stroke tolerance was critical for our aerospace application. Delivery was on time—unlike our previous supplier.”

Markus Weber

Senior Engineer, Aerotech GmbH (Germany)

“We needed 12V solenoids with 30N force for our medical device. YIDI delivered custom prototypes in 2 weeks and scaled to 5,000 units/month. Their IP67 rating passed our sterilization tests.”

❓ Q: What’s the difference between AC and DC linear solenoids?

DC solenoids (e.g., 12V/24V) are quieter, more precise, and ideal for battery-powered systems. AC solenoids (110V/230V) handle higher forces but require continuous power to hold position. YIDI’s recommendation: Use DC for portable/low-power apps, AC for industrial high-force needs.

❓ Q: Can you customize the stroke length and force?

Yes. We tailor stroke (2mm–50mm), force (5N–100N), voltage, and materials (e.g., stainless steel for corrosion resistance). MOQ: 100 units for custom designs. Lead time: 4–6 weeks.

❓ Q: How do I choose between a push, pull, or push-pull solenoid?

• Push: For compression (e.g., valves, switches).
• Pull: For retraction (e.g., latches, locks).
• Push-Pull: For bidirectional motion (e.g., sorting systems).

Not sure? Send us your specs—we’ll recommend the best fit.

❓ Q: What’s your lead time for bulk orders?

Standard models: 2–4 weeks (100–1,000 units). Custom designs: 4–6 weeks. Urgent? We offer rush production for key clients (contact us for availability).

❓ Q: Do you provide samples?

Yes! Free samples for standard models (shipping costs apply). For custom designs, we charge a one-time tooling fee (refundable with bulk orders).

❓ Q: What payment methods do you accept?

TT (Bank Transfer), L/C, PayPal, Western Union. For long-term partners, we offer 30–60 day credit terms (subject to approval).

⭐⭐⭐⭐⭐

“YIDI’s 12V linear solenoids replaced our failing US-brand units. Zero defects in 6 months, and the price was 40% lower. Their tech team helped us optimize the stroke for our sorting machine. Highly recommend!”

Pierre L.

Purchasing Manager, France

⭐⭐⭐⭐⭐

“We were skeptical about Chinese suppliers, but YIDI changed our mind. Their IP67-rated solenoids withstood our harsh outdoor conditions, and the CE certification made compliance easy. Delivery was 2 weeks early.”

Elena K.

R&D Director, Germany

⭐⭐⭐⭐⭐

“YIDI’s custom 24V solenoids with 20mm stroke were perfect for our aerospace prototype. Their engineers provided detailed FEA analysis to ensure reliability. Best supplier we’ve worked with in Asia.”
