Ultra-Thin Flexible NTC Sensors for Temperature Sensing in Tight Spaces

For space-constrained applications, the Semitec STS3 flexible thin-film NTC sensor offers a compact and high-performance solution. An extension of the Semitec JT series, it features a 25mm sensing tip, 600mm flexible lead, and a plug-in connector for easy integration or direct connection to a control p.c.b.

At just 0.5mm thick at its sensing tip, Semitec’s STS3, from ATC Semitec, is the world’s thinnest flexible NTC sensor. Its polymer-encapsulated element provides durability and flexibility. This flexibility allows the sensor to be placed closer to the heat source, delivering optimum temperature control in space-sensitive applications.

Key specs:

  • Response time: <1s
  • High accuracy: ±1%
  • Operating temperature: -40°C to 125°C
  • Fully intercahngeable
  • For air and surface temperature monitoring including batteries, medical devices, fire & heat detectors, boilers.
