Question 3

How to choose between different Optical Sensors - Phototransistors brands?

Accepted Answer

1. Pre-Screen with Industry Certifications (ISO, UL, CE)
Verify compliance with safety certifications like Industry Standards to filter 68% of subpar vendors.
2. Analyze Authentic Customer Reviews
Check platforms like Trustpilot/B2B forums for verified purchase reviews focusing on durability (avg. 4.2★+ recommended).
3. Calculate Long-Term Cost Efficiency
Use formula: Total Cost = (Price × Quantity) + (Failure Rate × Repair Cost) to compare 3-year ROI.
4. Request Sample Testing Reports
Require brands to provide third-party lab reports (e.g., SGS/BV) covering [Such as Brand:American Bright LED, ams OSRAM, Broadcom Limited]. 5. Finalize with On-Site Audit (Optional)
For bulk orders, inspect production facilities using QC checklist templates (Download Free PDF).
