Product Description

Anti Corrosion Potting Epoxy Small Black Head NTC Thermistor

Anti Corrosion Potting Epoxy Small Black Head NTC Thermistor is specifically designed for long-term temperature monitoring in outdoor new energy equipment. Featuring an anti-corrosion modified epoxy full potting structure, the sealed black small head effectively resists coastal salt fog, high humidity condensation, dust, and weak chemical volatile gases in outdoor cabinet environments. We support a full resistance range from 5K Ohm to 100K Ohm for selection, covering mainstream temperature control parameters of energy storage battery packs, photovoltaic inverters, and charging piles. Equipped with complete insulated anti-aging lead wire, it prevents insulation cracking and short circuits caused by long-term outdoor ultraviolet irradiation. This temperature sensor focuses on 24-hour continuous temperature detection for solar energy storage cabinets, outdoor charging equipment, and power distribution boxes, providing over-temperature early warning and thermal protection for lithium battery energy storage systems, effectively preventing thermal runaway safety risks in energy storage equipment.

Key Characteristics

Anti-corrosion modified epoxy integral potting provides strong salt spray and humidity resistance, adapting to coastal outdoor harsh environments
Full resistance range 5K to 100K optional, matching different energy storage inverter and BMS management board parameters
Complete insulated anti-UV lead wire prevents aging and cracking under long-term outdoor sunlight exposure
Excellent humidity endurance with stable performance under 85℃ / 85%RH high temperature and high humidity double 85 aging test
Compact small black head structure for easy installation in narrow spaces of energy storage cabinets and charging modules
Fast temperature response speed for timely capture of abnormal battery pack temperature rise to trigger thermal protection

Production Technology

The manufacturing process employs anti-corrosion targeted workflow specifically designed for new energy outdoor sensors. Core processes include high stable NTC ceramic chip sorting, low resistance silver electrode printing, anti-UV insulated lead welding, multi-layer anti-corrosion epoxy vacuum potting, constant temperature slow curing, double 85 high temperature and humidity aging screening, salt spray corrosion resistance testing, and insulation withstand voltage inspection. The vacuum potting process eliminates internal bubbles within the epoxy layer to prevent moisture and salt fog penetration. All finished products pass 72-hour high humidity aging screening, eliminating chips with significant resistance drift to guarantee long-term stable temperature sensing for outdoor energy storage equipment.

Frequently Asked Questions

Can this anti-corrosion epoxy NTC thermistor work stably in coastal high salt fog outdoor energy storage cabinets?

Yes, we employ multi-layer anti-corrosion modified epoxy full potting process. Finished products pass salt spray corrosion testing and 72-hour high humidity double 85 aging tests, ensuring stable long-term operation in coastal high humidity salt fog cabinet environments.

Does this product support customized resistance values outside the 5K~100K range?

Yes, we can customize special resistance values, B-values, and lead lengths according to the temperature control parameters of customers' energy storage inverters and BMS boards.

Why is this NTC more suitable for outdoor energy storage cabinets than ordinary epoxy NTCs?

Ordinary single-layer epoxy NTCs lack anti-corrosion and anti-salt fog capabilities, making them prone to moisture absorption and resistance drift in closed damp cabinets. Our model utilizes special anti-corrosion potting epoxy and anti-UV aging wire, specifically designed for outdoor new energy long-term unattended temperature monitoring.
