High Reliability PTC Temperature Sensor Coding Of The Temperature Through Wire Colours

PTC Thermistor Limiting Temperature Sensor Description: PTC thermistor, a bushing type for over-temperature protection, is used for over-temperature detection of windings in motors, coils, transformers, equipment, machines, etc. Can be used as 1 PTC single sensor and 3 PTC series triple sensors

Application
 

◆ Limit temperature monitoring

◆ Electrically actuated motors

◆ Mechanical engineering

◆ Heavy-duty Motors

PTC thermistor temperature sensor features:
 

·Thermistor chip with insulating package
·Low resistance type, steep R/T curve.
·Small size, fast response.
·Sensing temperature characteristic conforms to DIN 44081 1 PTC single sensor, DIN 44082 conforms to 3 PTC three sensors in series.
·No need to reset the power supply after switching over temperature.
· For 1 PTC single sensor, color code the twisted wires according to DIN 44081. For 3 triple sensors of the PTC series, the twisted wires are color coded according to DIN 44082, the connecting wires are yellow.
