Frequently asked questions
Selection, compatibility, customization, lead time and warranty questions from OEM buyers and distributors.
What is the difference between an SSR and a mechanical relay?
Solid State Relays (SSRs) use semiconductor components to switch loads silently and quickly, while mechanical relays use physical contacts. SSRs are ideal for high-frequency switching and environments where noise-free operation is needed.
Can your SSRs be used with PLCs, microcontrollers, or Arduino?
Yes. Most of our SSRs operate with 3–32VDC input signals, making them compatible with PLCs, Arduino boards, and industrial controllers.
Do you offer custom thermocouple or sensor cable lengths?
Absolutely! We support customization of length, thread size, probe diameter, and wire type. Just send us your requirements.
What's the typical lead time for bulk orders?
For standard models, lead time is 3–5 working days. For OEM/custom orders, we will confirm the schedule upon order placement.
How can I choose between K Type and Pt100 sensors?
K Type thermocouples are suitable for fast, general-purpose temperature measurements up to 800°C. Pt100 (RTD) sensors offer higher accuracy and better long-term stability, usually up to 300°C.
Do your products include warranty?
Yes, all standard products come with a 12-month warranty . If anything goes wrong due to quality, we’ll provide technical support or replacements.
