TF1 Analog Non-Contact Inductive Linear Transducer

Manufacturer: Novotechnik
Category: Displacement, SENSORS, Linear Transducers

Novotechnik TF1 analog inductive transducer. NOVOPAD inductive technology, contactless.

Non-contact linear inductive position transducer with active floating position marker. Stroke from 100 to 1000 mm. Reproducibility up to 5 µm. IP67 protection. Principle: emitter and receiver coils on the same board; the marker induces a current in the receivers, with sine/cosine structures on a thick and a thin track.

Key points

Unlimited mechanical life (with floating placeholder)
Refresh rate: 10 kHz
Reproducibility: up to 5 µm
IP67 protection: a GORE membrane equalizes pressure in response to temperature changes

Technical Frequently Asked Questions

What can be connected to the TF1 analog inductive transducer?

It can be connected to Novotechnik M12 connectors and cables and Novotechnik linear sensor positioners (magnets and cursors).

How do I order the TF1 analog inductive transducer?

The order code has six fields: stroke (mm), mechanical version, interface, signal, feature, and connection. For example, TF1-0800-001-411-102 is the version with an 800 mm electrical range, profile, analog interface, 0–10 V output voltage, 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 TF1 analog inductive transducer operate?

Operating temperature: -40 … +85 °C. Protection: IP67, with GORE membrane pressure equalization, with the connector fixed.
