Main features

Magnet fixing type cost performance sensor

This sensor uses ST-50 as a sensing element. Simple construction provides cost performance.

Easy sensor replacement

The sensing part is our ST-50, enabling easy replacement of the sensor.

The dedicated cable with connector for ST-50 (sold separately) is used

The dedicated cable with connector for ST-50 (sold separately) is used.

※Necessary when STM-A is used. This cable is sold separately.

Main specification

• Magnetic force
• Sensor type: Type K thermocouple, class 2 (JIS C 1602-1995)
  3N to 7N (Flat surface of iron)
• Accuracy
  ±2°C (Flat surface of 100°C)
• Measuring range
  0 to 300°C (no condensation)
• Response time
  STM-A-P/G-100： 0.5 sec. (90%) typ.value
  STM-A-G-300/500： 1.5sec. (90%) typ.value
  ※The sensor should be placed and left in a room at a room temperature. Then the sensing part is contacted with the 100°C magnetic flat surface, is evaluated at the 90% point of the stability point.
