Key Features of the Wire Harness:
- Twisted Pair Anti-interference Design
Red and black wires are tightly twisted, effectively suppress electromagnetic noise. It ensures accurate and stable temperature signal transmission even in complex battery working environment.
- High Thermal Conductivity Sensing Patch
Flat metal patch provides fast heat transfer, responds quickly to temperature variation. It can be closely fitted on battery surface for precise temperature monitoring.
- Reliable 2Pin White Connector
White locking plastic connector features easy assembly and maintenance. Snap lock prevents loose contact caused by vibration.
Solid Soldering Connection The joint between wire and metal patch is soldered firmly, strong pull resistance, not easy to break during long-term vibration.
Support custom wire length, patch dimension and NTC resistance value (10K, 100K etc). Meet different lithium battery pack design requirements.
Ideal for LiFePO4 / NCM lithium battery packs, portable power stations, e-bike batteries, energy storage systems, power tool battery temperature monitoring.
FAQ
Q1: What is the main benefit of twisted pair wire harness?
A1: The twisted structure reduces electromagnetic interference (EMI). It keeps signal stable when working near power cables or high-current battery modules, widely used for BMS signal collection.
Q2: Can I customize the length and tab size of this wiring harness?
A2: Yes. We fully support custom length, wire gauge, nickel tab dimensions and connector types. Send us your drawing or specification for quotation.
Q3: How do you inspect solder joints to avoid virtual soldering?
A3: We use 3-layer QC: visual inspection after stripping heat shrink tube, low resistance test and pull force test. Defects such as poor wetting and cold solder joints will be rejected.
Q4: What applications are these tab wire harness suitable for?
A4: Mainly for battery pack BMS sampling lines, temperature sensors, industrial electronic modules and low-voltage signal collection systems.
Q5: What is your minimum order quantity?
A5: Flexible MOQ for prototype and mass production. Small sample orders are welcome for project validation.
