An ATC Semitec product story
Edited by the Engineeringtalk editorial team Jul 7, 2005

When Semitec developed a new surface-mounting ring terminal sensor using its latest AP series NTC thermistor, the company wanted to improve on a couple of aspects of its existing all-plastic design.

When Semitec developed a new surface-mounting ring terminal sensor using its latest AP series NTC thermistor, the company wanted to improve on a couple of aspects of its existing all-plastic design.

By combining a stainless steel base with a high-grade plastic moulding, the company has achieved a 25% faster thermal response and an improved dielectric isolation up to 1200V AC for 1s.

By using the new AP series thermistor, the new sensor is economically priced and is interchangeable to better than +/-0.5K over 0-70C.

The operating temperature range actually covers from -60 to +150C, with a wide selection of R25 values from 2ohm to 200kohm.

The standard part has rigid leads at a 2.54mm pitch, but flexible leads complete with connectors can be supplied if preferred.

There is also a further version still in development with an operating temperature of up to 200C.
