Technical Frequently Asked Questions
What can be connected to the TH1 pulse magnetostrictive transducer?
It can be connected to Novotechnik M12 connectors and cables, Novotechnik M16 connectors and cables, and Novotechnik linear sensor positioners (magnets and cursors).
How do I order the TH1 pulse magnetostrictive transducer?
The order code has 6 fields: stroke (mm), mechanical version, interface, signal, markers, and connection. For example, TH1-0800-102-111-102 is the version with an 800 mm electrical range, M18x1.5 threaded flange with a 30 mm zero point, Start/Stop pulse interface for 1 position marker, and an 8-pin M12x1 connector. All the options for each field are available in the order code configurator on this page.
Under what conditions does the TH1 pulse magnetostrictive transducer operate?
Operating temperature: -40 … +85 °C. Protection: IP67.
