3 Functions and features

The unit is used as an optical distance sensor.

3.1 Applications

• The optical distance sensor measures distances between 0.03 and 2 m.
• It has a background suppression of up to 20 m.
  • The switching outputs are complementary.

The distance between the sensor and the background must be limited to max. 20 m by the customer. Otherwise measured values can be ambiguous → 4.1 Installation conditions.

4 Installation

4.1 Installation conditions

▶ Install the unit so that the object to be detected is within a measuring range of 0.03...2 m.

Any object between the set switch point and a distance of 20 m from the sensor is suppressed.

Reflecting surfaces in the direct beam path of the sensor – also in the range > 20 m – are to be avoided by the customer. Otherwise the measured values can be ambiguous.

5 Electrical connection

The unit must be connected by a qualified electrician.

▶ The national and international regulations for the installation of electrical equipment must be adhered to.
▶ Ensure voltage supply to EN 50178, SELV, PELV.

▶ Disconnect power.
▶ Connect the unit as follows:

DC PNP

4: OUT1 = normally open / IO-Link
2: OUT2 = normally closed

DC NPN

4: OUT1 = normally open / IO-Link
2: OUT2 = normally closed

Core colours of ifm sockets:

1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black)

6 Setting /operation

1: Setting marks
2: LED yellow: Set1 value reached, output = ON
3: Locking ring
4: Setting ring (manually adjustable after unlocking)
5: LED green: operating voltage OK

- To achieve the setting accuracy: First position the setting ring to the upper end stop value, then to the requested value.

▶ After installation, electrical connection and programming, check whether the unit operates correctly.

Lifetime of a laser diode: 50,000 hours

7 IO-Link

7.1 General information

This unit has an IO-Link communication interface which requires an IO-Link-capable module (IO-Link master) for operation.

The IO-Link interface enables direct access to the sensor values and parameters and provides the possibility to set the parameters of the unit during operation. In addition communication is possible via a point-to-point connection with a USB adapter cable.

You will find more detailed information about IO-Link at www.ifm.com.

7.2 Device-specific information

You will find the IODDs necessary for the configuration of the IO-Link device and detailed information about sensor values, diagnostic information and parameters in the overview table at www.ifm.com.

7.3 Parameter setting tools

You will find all necessary information about the required IO-Link hardware and software at www.ifm.com.

8 Maintenance, repair, disposal

Faulty sensors must only be repaired by the manufacturer.

▶ Keep the front lens of the sensor clean.
▶ After use dispose of the unit in an environmentally friendly way in accordance with the applicable national regulations.
▶ Do not open the module housing. There are no user-serviceable components inside.
