In CCTV applications where the product location makes them difficult and costly to maintain, you want to ensure any components used are completely reliable. They must give a consistent and accurate performance over a long life-time.
Fortunately Matsuo MQT series thermostats are IP64 rated, have excellent repeatability (within ±0.2K) and life-cycles of up to one million operations. They out-perform cheaper disc thermostats on every level and help to minimise costly maintenance calls.
The Matsuo thermostats are superior owing to a unique twin-bimetal system that is stress-free and thus limits set-point drift and maximises cycle-life. They are ideal for anti-condensation/anti-frost applications where the sealed housing protects the contacts and can be supplied with accuracies as small as ±1.5K with differentials down to 3K±1K. Calibrations from -10/+110ºC are available.
