Resistance Value Testing
Each sensor is measured at reference temperature to verify resistance value against specification tolerance using calibrated precision bridges.
B Value Verification
B constant is verified by measuring resistance at two reference temperatures, confirming the thermistor characteristic curve matches specification.
Insulation & Dielectric Test
Insulation resistance and dielectric strength tests are performed on cable assemblies, particularly for high-voltage ESS and automotive applications.
Cable & Connector Inspection
Cable continuity, connector engagement force, and crimping quality are checked to ensure reliable electrical connection and mechanical integrity.
Pull Force Test
Tensile pull force testing on cable-to-probe joints and connector terminations verifies mechanical strength meets the requirements for the intended installation environment.

Frequently Asked Questions
Common Questions About Custom NTC Sensors
Answers to the most common questions from engineers, procurement managers, and product teams evaluating custom NTC temperature sensor suppliers.
Can I customize the NTC resistance value and B value?
Yes. We support custom resistance values (10K, 50K, 100K, or other values on request) and custom B constants (B3435, B3950, B3977, or per your specification). Please provide your target resistance value, B value, and reference temperature when submitting your inquiry.
Can I specify a custom cable length and connector type?
Yes. Cable length is fully customizable. We support JST, Molex, TE, AMP, and equivalent connectors, and can match your existing harness design. Provide the required length, connector part number or mating connector sample, and we will confirm compatibility.
Can you manufacture according to my drawing or sample?
Yes. We accept 2D/3D drawings, physical samples, or written specifications as the basis for production. If you have an existing sensor you need to replicate or improve, send us the sample and we will evaluate it for reverse engineering.
Do you supply NTC sensors for battery pack and BMS applications?
Yes. Battery pack and BMS temperature sensing is one of our primary application areas. We have dedicated production lines for automotive-grade sensors and can supply sensors with AEC-Q200 test reports from CNAS-accredited laboratories. We work with BMS manufacturers, battery pack integrators, and EV OEM supply chains.
Can you produce multi-point NTC sensor harnesses?
Yes. We manufacture multi-point NTC sensor harnesses with sensors positioned at defined intervals along a single cable assembly. This is commonly used for battery module temperature mapping and ESS rack monitoring. Provide your layout drawing with sensor positions, cable routing, and connector requirements.
What resistance values are most commonly available?
The most commonly used values are 10K Ω (standard for automotive and BMS) and 100K Ω (common in industrial and HVAC applications). 50K Ω is also available. Other resistance values can be produced based on your specification -- contact us with your target value and we will advise on feasibility and lead time.
What information do I need to provide to get a quote?
To prepare an accurate quotation, it helps to provide: (1) resistance value and B value, (2) resistance tolerance, (3) probe type and mounting method, (4) cable type and length, (5) connector type, (6) operating temperature range, (7) application description, and (8) estimated annual quantity. A drawing or sample is also helpful but not required to start the conversation.
Can I get samples before placing a production order?
Yes. We support prototype and sample production prior to mass production. Sample quantities and lead times vary depending on the complexity of the customization. Please contact us to discuss your sample requirements and we will advise on the timeline.
Do you support small-batch trial orders and large-volume production?
Yes. We support both small-batch trial production for new projects and high-volume mass production. Our 36 automated production lines with a combined capacity exceeding 2 million units per day allow us to scale with your project from initial trial to full-volume supply.
How do I select the right NTC temperature sensor for my application?
Key selection factors include: (1) operating temperature range -- determines probe and cable material; (2) required accuracy -- determines resistance tolerance grade; (3) mounting method -- determines probe type (epoxy, metal shell, ring terminal, flat, etc.); (4) electrical interface -- determines connector and cable type; (5) environment -- determines insulation and protection requirements. Share your application details and our engineering team will recommend a suitable configuration.
