Amphenol Advanced Sensors JI/JIC Waterproof IP68 NTC Thermistors

Amphenol Advanced Sensors JI and JIC Waterproof IP68 NTC Thermistors are molded onto a flexible circular cable. The tip and outer cable insulation material are designed with thermoplastic elastomer rubber and the tinned copper conductors feature individual polypropylene insulation. These thermistors come in wire lengths from 300mm to 5000mm, withstand freeze/thaw cycling, and operate within a -50°C to +105°C temperature range. The JI and JIC thermistors are used in ventilation, refrigeration, heat pumps, and weather stations.
