This document describes the OID20x optical distance sensor, providing operating instructions and essential information for its safe and effective use.

Function Description

The OID20x is an optical distance sensor designed to measure distances between 0.03 and 2 meters. It features background suppression up to 20 meters, meaning it can ignore objects beyond a set switch point up to this distance. The sensor provides complementary switching outputs. It utilizes a Class 2 visible laser light for operation. The unit can be configured via an IO-Link interface, allowing direct access to sensor values and parameters. It can also be used without IO-Link, with a preset switch point of 2 meters upon delivery.

Important Technical Specifications

Measuring Range: 0.03 to 2 meters.
Background Suppression: Up to 20 meters.
Laser Class: Class 2 (Visible laser light).
Laser Parameters (Product Label): Max. power ≤ 4.0 mW, pulse 1.3 ns, λ = 650 nm.
Laser Diode Lifetime: 50,000 hours.
Outputs: Complementary switching outputs (OUT1: normally open / IO-Link, OUT2: normally closed).
Input (Pin 5): Laser on / off control.
Electrical Connection: DC PNP, requiring voltage supply to EN 50178, SELV, PELV.
Compliance: EN/IEC 60825-1: 2007 and EN/IEC 60825-1: 2014, complies with 21 CFR 1040 except for deviations pursuant to Laser Notice No. 50, dated June 2007. The unit also complies with EN 61000-6-4.
IO-Link: Communication interface requiring an IO-Link-capable module (IO-Link master) for operation. Communication is also possible via a point-to-point connection with a USB adapter cable.

Usage Features

Installation: The unit should be installed so that the object to be detected is within its measuring range of 0.03 to 2 meters. Reflecting surfaces in the direct beam path, even beyond 20 meters, should be avoided as they can lead to ambiguous measured values. The distance between the sensor and the background should be limited to a maximum of 20 meters by the customer to prevent ambiguous readings.
Electrical Connection: Connection must be performed by a qualified electrician in adherence to national and international regulations. Power should be disconnected before connecting the unit. The core colors for ifm sockets are: 1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black), 5 = GR (grey).
Operating and Display Elements: The unit features a yellow LED (1) that indicates when the set value is reached, and output OUT1 is High (if configured as NO).
Settings / Operation: The unit's settings are primarily configured via the IO-Link interface. Upon delivery, it can be used without IO-Link with a preset switch point of 2 meters. After installation, electrical connection, and programming, it is crucial to verify correct operation.
Laser Control: For safety and maintenance, the laser can be temporarily switched off via the input on pin 5. A "Low / not connected" signal on pin 5 keeps the laser "On," while a "High" signal switches it "Off."
IO-Link Integration: The IO-Link interface allows for advanced configuration and monitoring. Detailed information, IODDs, sensor values, diagnostic information, and parameter setting tools are available on www.ifm.com.

Maintenance Features

Repair: Faulty sensors must only be repaired by the manufacturer.
Cleaning: The front lens of the sensor should be kept clean to ensure optimal performance.
Disposal: After use, the unit must be disposed of in an environmentally friendly manner, in accordance with applicable national regulations.
User Serviceability: The module housing should not be opened as it contains no user-serviceable components. Tampering with or modifying the unit will void any liability and warranty.

Safety Instructions

Read Documentation: Always read the product documentation before setting up the unit to ensure suitability for the application.
Qualified Personnel: Installation, electrical connection, set-up, operation, and maintenance must be carried out by qualified personnel authorized by the machine operator.
Intended Use: Improper or non-intended use can lead to malfunctions or unwanted effects.
Malfunction: In case of malfunction, contact the manufacturer.
Laser Safety:
- Visible laser light, Class 2 laser product.
- Do not stare into the laser beam.
- Avoid exposure to the laser beam.
- Unplug the connector to extinguish the laser beam.
- Use of controls or adjustments other than those specified may result in hazardous radiation exposure and potential retinal damage.
- Apply the enclosed laser warning labels in the immediate vicinity of the unit.
- Adhere to caution and warning notes on the product label.
- Use the enclosed label for the power supply cable.
Electromagnetic Compatibility: The unit complies with EN 61000-6-4. If radio interference occurs in domestic areas, the user must take remedial actions.
