   Description
    These high-quality and robust mini temperature switches have been developed especially for safety-critical applications. High quality and product manufacturing
ensures reliable monitoring of your plant. The manufacturer Cella is certified to ISO 9001. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested.
    All wetted materials are from stainless steel as a standard AISI 316. Each switch family is available in IP 65, Ex-ia or Ex-d versions.

    In order to ensure as flexible operation as possible, the temperature switches are fitted with micro switches, which enable the switching of an electrical load of up to 5 A/AC 220 V directly. For smaller contact ratings, such as for PLC applications, hermetically-sealed micro switches with gold-plated contacts can be selected as an option.With its flexible AISI 316 spiral protective sleeve, the
model TXA temperature switch is extremely robust and guarantees optimal operating characteristics for applications requiring particularly high corrosion protection.
