Frequently Asked Questions - RU6040 IFM

What is the power supply voltage of the RU6040?

The encoder is available in two versions: 5 V TTL or 10...30 V HTL. Check the exact model on the label.

How to connect the RU6040 encoder?

Disconnect power before any connection. Use the connection diagram provided on the cover or in the manual. Observe the terminals L+, 0V and outputs A, B, index.

What is the maximum allowed cable length?

For the 5 V TTL version: 100 m. For the 10...30 V HTL version: 300 m. Use shielded cables separated from interference sources (distance > 20 cm).

How to interpret the output signals?

Outputs A and B are digital pulses phase-shifted by 90° to detect the direction of rotation. The zero index is emitted once per mechanical revolution.

Can I use this encoder to measure linear displacements?

Yes, using a measuring wheel or a rack and pinion. Ensure not to exceed the permissible loads on the shaft.

How to mount the RU6040 encoder?

Screw the encoder onto a mounting flange (ref. E60033). Use a flexible coupling to avoid axial stresses. Avoid shocks to the shaft.

What to do if a wire is not used?

Insulate unused wires to avoid short circuits. You can also connect them to the supply voltage if necessary.

Where to find accessories for the RU6040?

Visit www.ifm.com for datasheets and accessories such as cables, connectors, and flanges.

Is the encoder protected against short circuits?

Yes, the outputs are protected against short circuits: on 0 V for the TTL version, on 0 V and L+ for the HTL version (max 1 minute).

Can I repair the encoder myself?

No, no user repair is intended. In case of failure, contact IFM after-sales service or replace the device.

Function and features

The encoder transforms rotational movement into pulse sequences. These allow the measurement of linear distances and angular movement as well as the determination of positions.

Electrical connection

Disconnect power from the installation before connecting or disconnecting cables or connectors!

Unused wires must be insulated to avoid short circuits and cross faults.

Short-circuit protection

5 V TTL version: outputs short-circuit protected against 0 V

10...30 V HTL version: outputs short-circuit protected against 0 V

Wiring is also indicated on the housing cap. If there is a deviation, the encoder must be connected as indicated on the label on the housing cap.

The wires L+ (sensor) and 0V (sensor) are internally connected to the supply voltage. When using external electronics which regulate the supply voltage these wires can be used as test wires. If unused, these wires must be connected to the supply voltage or insulated.

Depending on the version, the electrical connection is made via the cable or via cables to be obtained separately.

When using suitable cables the maximum cable length is 100 m for the 5 V TTL version and 300 m for the 10...30 V HTL version.

The cables must be laid separately from interfering sources, the minimum distance is 20 cm.

The braided screen in the cable is connected to the encoder housing.

Output signals

output A

output B

0 index

The encoder provides digital pulse sequences at the output stages.

The outputs A and B are electrically offset by 90^ . Thus the direction of rotation can be evaluated in the external electronics.

The combined zero index is provided once in a mechanical revolution of the shaft. In case of power failure it can be used as a reference point within a revolution.

The inverted output signals are used for external electronics with differential voltage input to filter interference.

Installation

Do not hit the shaft, do not use a file or similar tool on the shaft: This could destroy the unit!

The encoder can be screwed to the angle bracket. The shaft should be connected using a flexible bellows or spring disc coupling to compensate for shaft displacement and to protect the encoder against damage.

Linear movements can be transformed into a rotational movement using a measuring wheel or rack and pinion. For mounting the maximum permissible shaft loads of the encoder must be taken into account.

Mounting the angle bracket on a resilient base protects the encoder against too high a stress due to roughness of the material.
