To increase the dielectric strength the PTC thermistor are mostly equipped with a shrinkable tubing insulation.

Features
• miniaturized thermistor temperature sensor at a diameter <3mm • selection of nominal response temperature (NAT) available • increase of dielectric strength when insulated by shrinkable tube • thermal response time below 5 s • IECEx und ATEX certification for the use in hazardous areas • TR certificate for the Eurasian Customs Union Application The miniaturized PTC thermometers are ideal for motor protection. They enable the temperature-dependent switching on or off at a temperature predetermined by the selected thermistor. Structure / Functional principle The single, double or triple PTC miniature thermistors are available at nominal response temperature (NAT) from +60°C to +190°C. The respective NAT is indicated by the colour coding of the DIN-compliant PTFE single wire. Here, the NAT is + 155 ° C. For multiple thermistors (double / triple PTC) the inner connections are encoded yellow. The isolated sensor pill has a maximum outer diameter of 3 mm.
