STS2 Ring Terminal Temperature Sensors

Ring terminal temperature sensors available with plastic, metal or plastic/metal rings.  The NTC thermistor is embedded in the ring terminal housing to maximise the sensor’s thermal response.

Our neat over-moulded ring sensors have been widely adopted in various markets including E-vehicles.  The over-moulded sensor design combines electrical isolation as well as thermal insulation to help minimise heat-loss away from the sensor.

Applications

  • Electric Vehicle Batteries
  • Rechargeable Batteries
  • Heat-sink monitoring
  • Heating and air conditioning
  • Motor bearing monitoring
  • Hot water appliances

Features

  • Fast response design (Tc ≤ 5s)
  • Accuracy ±1% or better
  • Over-moulded ring design option
  • Interchangeability between NTCs
  • Standard ring sizes (M3, M4, M5 or larger)
  • 1500VAC Dielectric strength
  • Excellent long-term stability
  • Operating range up to +150°C
