Frequently Asked Questions - RO1362 IFM

Which supply voltage should I choose for my IFM RO1362 encoder?

The encoder is available in two versions: 5 V TTL and 10...30 V HTL. Check the label on the housing for the exact version. The HTL version supports a wider voltage range.

How to connect the RO1362 encoder?

Connection is made via a male 12-pin connector or a 13-wire cable. Follow the wiring diagram provided on the housing cover. Always disconnect the installation from power before connecting or disconnecting cables.

What is the maximum cable length?

For the 5 V TTL version, the maximum length is 100 m. For the 10...30 V HTL version, it can reach 300 m provided appropriate cables are used.

How to mount the encoder on a shaft?

Slide the clamping nut onto the encoder, insert the shaft of at least 10 mm into the encoder, fix the stator coupling with four M3 screws, then tighten the nut. Avoid shocks to the shaft.

What do outputs A, B and Index 0 mean?

Outputs A and B are digital pulses phase-shifted by 90°, which allows determining the direction of rotation. Output Index 0 emits a pulse once per mechanical revolution, serving as a reference.

How to protect the encoder from electrical interference?

Install cables at least 20 cm away from interference sources. The braided shield of the cable is connected to the encoder housing. If possible, use differential inputs for the inverted signals.

Is the encoder protected against short circuits?

Yes. The 5 V TTL version protects outputs against short circuits on 0V. The HTL version protects both on 0V and L+ (for a maximum of 1 minute).

Can I use the encoder to measure linear displacements?

Yes, by combining the encoder with a measuring wheel or a rack and pinion. The maximum permissible shaft loads must be observed.

Where to find accessories or technical datasheet?

Visit the website www.ifm.com to download the technical datasheet, supplementary documents, and order suitable accessories.

What to do if the sensor L+ and sensor 0V wires are not used?

These wires are internally connected to the supply. If not used, either connect them to the supply voltage or insulate them carefully to avoid any short circuit.

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 and L+ for maximum 1 minute

Standard wiring:

	Flange plug 13-wire cable 12-pole
L+ M brown/green
L+ sensor B blue
0V K white/green
0V sensor L white
A E brown

0 index	C	red
0 index neg.	D	black
fault neg.	G lilac

screen	housing	housing

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 100m for the 5 V TTL version and 300m 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

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!

Continuous hollow shaft

1. Place the clamping nut on the encoder.
2. Slip the encoder onto the shaft (min. 10mm ) and fix the stator coupling by means of four M3 screws.
3. Tighten the screws of the clamping nut.

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.
