Yes. We supply ring terminal and flat probe NTC harnesses for busbar surface monitoring, and single or multi-point harnesses for inverter thermal management and industrial equipment over-temperature protection.
What information do I need to provide for a quotation?
To provide an accurate quotation, it helps to know: application type, number of sensing points, NTC resistance and B value, probe type, cable material and length, branch lengths, connector and terminal type, mounting method and estimated annual quantity. A drawing or wiring diagram is helpful but not required to start.
Can you produce harnesses based on drawings, samples or wiring diagrams?
Yes. We accept production based on customer drawings, physical samples, wiring diagrams, connector part numbers or written specifications. Any reference material helps reduce development time.
Can you provide samples for testing before mass production?
Yes. We produce prototypes or pre-production samples for customer evaluation and confirmation before mass production begins. Sample testing is part of our standard development process.
How do I choose between a single-point and multi-point NTC sensor harness?
If you need to monitor temperature at one specific location, a single-point harness is suitable. If your application requires monitoring multiple locations -- such as across battery modules, ESS cells or equipment zones -- a multi-point harness consolidates all sensing into one assembly with a single connector interface to your BMS or control system.
