PTC Thermistors from Thermik
As one of the few manufacturers of PTC ceramics, THERMIK brings much experience. Basic technology is greatly significant in manufacturing, and our thermistors and PTC motor protection sensors are of much higher quality than standard products.
The PTC‘s are usually installed parallel to the coil so that the mechanical strain is minimized. The Mylar-Nomex shrink cap is well suited due to its mechanical stability (no cold flow, as opposed to Teflon). In conjunction with the miniature pill (Ø 1,5 mm), response times of ≤ 5 seconds to a maximum of 10 seconds are achieved.
THERMIK thermistors correspond to DIN 44081, DIN 44082, and IEC 34-11-2, and exhibit a very high temperature sensitivity. The resistance increases strongly in the area of the rated response temperature. This change can be used to switch off the load circuit through a triggering device. Electronic evaluations of many different applications are also possible. The typical characteristics of THERMIK thermistors are presented in the temperature resistance diagram.
- Small dimensions + mechanical stability
- Fast response times
- Temperature-resistance characteristic tailored to the application in question
- Color coding
- Cable insulation material or cable cross-section
- Cable-end assembly
- Connection technology
- Components used with UL-cable
- High voltage proof insulation (suitable for installation in Class II applications)
