Technical Frequently Asked Questions

What can be connected to the IP67 potentiometric transducer, LWX-004?

It can be connected to Novotechnik M12 connectors and cables, Novotechnik linear sensor couplings and mountings, signal conditioners for standardized output signals (e.g., MUP-110) MUP, signal conditioners for standardized output signals MUK, and process-controlled indicators with MAP display.

How do I order the IP67 potentiometric transducer, LWX-004?

The order code has three fields: stroke (mm), model, and connection. For example, LWX-0150-004-101 is the version with a defined electrical stroke of 150 mm, model 004, and an M12x1 connector output. With 201 instead of 101, the output is a 1 m cable. All order references with their corresponding part numbers are listed in the reference table on this page.

Under what conditions does the IP67 potentiometric transducer, LWX-004, operate?

Operating temperature: -30 … +100 °C. Protection: IP 67, also dynamic.
