I. PLCs and Controllers: Siemens
For PLCs and controllers, consider Siemens and Schneider Electric. According to industry consensus, the best PLCs globally are from Siemens (Germany), low-voltage electrical components from Schneider Electric (France), and safety relays from Pilz (Germany).
Siemens’ SIMATIC series is widely recognized as a top choice in the industrial control field.
Based on purchasing experience, Schneider Electric PLCs operating on 24-hour production lines have a response speed approximately 15% faster than the national standard, making the extra 30% worthwhile.
II.
Servo Drives: Yaskawa and ABB
For servo drives, consider Yaskawa, Siemens, and ABB.
According to industry analysis, the world’s best servo motors are from Yaskawa (Japan), and inverters are from ABB (Switzerland). German brands Siemens, Rexroth, and Lenze emphasize precision and industrial-grade reliability, and are mostly used in high-end manufacturing and heavy industry.
Japanese brands Panasonic, Yaskawa, and Mitsubishi together account for approximately 45% of the market share, making them the main buyers of servo motors.
**III. Pneumatic Components: SMC and Festo**
**Pneumatic components: SMC and Festo.** According to public information, SMC was founded in 1959 and has a sales network covering 83 countries worldwide, offering over 700,000 products.
German company Festo maintains a leading position in the domestic pneumatic industry. Procurement can be made through official SMC channels or authorized agents such as Shanghai Xizhen, Dapeng, and Qiantuo.
Commonly used models are shipped on the same day or the next day.
**IV. Bearings and Guide Rails: SKF and NSK**
**Bearings and linear motion: SKF, NSK, and THK.**
According to industry data, SKF has the most comprehensive online presence in China, with official flagship stores on SKF Mall, Tmall, and 1688, where customers can scan the QR code on the packaging to verify authenticity through SKF Authenticate. NSK has been manufacturing bearings since 1916;
THK is the world’s pioneer in linear guides.
Selection experience: For bearings, choose NSK or SKF for maximum durability.
V. Sensors: Keyence and Omron
Sensors: Keyence, Omron, and European/American brands.
According to industry reviews, for photoelectric sensors, Keyence and Cognex are the top choices; for temperature controllers, Omron is preferred. Among European/American brands, SICK excels in photoelectric and laser ranging, TURCK in proximity switches, P+F in ultrasonic sensors, IFM in process control, and Balluff in proximity switches and RFID.
Imported sensors are standard for precision detection scenarios.
Conclusion
Recommendations for imported automation components adhere to two principles: “Import for critical workstations to ensure accuracy, domestic for ordinary workstations to control costs.” For inspection workstations requiring accuracy of ±0.01mm, choose imported components; for ±0.05mm, domestic products are perfectly adequate.
FA standard parts from Yiheda and Shanglong can be comparable to MISUMI, but arbitrarily replacing them is not recommended for high-speed, heavy-duty, and high-precision critical positions.
When purchasing imported brands, ensure you use official and authorized dealer channels and verify the authenticity of the products—choosing the right channel ensures that imported components are worth the price.
