TF1 IO-Link contactless inductive linear transducer

Manufacturer: Novotechnik
Category: Displacement, SENSORS, Linear Transducers

Novotechnik TF1 IO-Link 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)
Output refresh rate: 1 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 IO-Link 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 IO-Link inductive transducer?

The order code has 5 fields: stroke (mm), mechanical version, interface, parameters, and connection. For example, TF1-0800-001-A11-107 is the version with an 800 mm electrical range, profile, IO-Link, 5 µm resolution in Balanced mode with position, and a 4-pole M12x1 connector. All the options for each field are available in the order code configurator on this page.

Under what conditions does the TF1 IO-Link inductive transducer operate?

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