MZ6 60℃~180℃ 32V Single Two Three Cores 520mm Motor-Specific PTC Thermistor Temperature Sensor For Thermistors
The PTC thermistor sensor is installed in thermal contact with the equipment to be protected and connected to the bridge arm of the comparator circuit. At normal temperature, the PTC thermistor (Rp) is lower than Rs, so the output voltage VO of the comparator will be low. If the device gets too hot, the PTC thermistor sensor will rapidly heat up to its trigger or nominal reference temperature, Tn, at which point its resistance will increase to a value well above Rs, causing VO to switch high enough to activate the alarm , a relay or power supply shuts down the circuit.
Application
◆ Limit temperature monitoring
◆ Electrically actuated motors
◆ Mechanical engineering
◆ Heavy-duty Motors
Features
◆ Very small size for a fast response
◆ Coding of the temperature through wire colours
