Model/Type: O1DLF3KG (O1D Series Laser Distance Sensor)

1. Product Characteristics & Application

• Sensor Type: Photoelectric Laser Distance Sensor (Time-of-Flight measurement)

• Measuring / Sensing Range (r): 0.2…10 m (On white target background)

• Communication Interface: IO-Link 1.1 enabled

• Laser Protection Class: Class 1 or Class 2 (Visible red laser light for alignment/measurement)

• Application: Precise long-range distance measurement, container fill-level tracking, collision avoidance, and positioning tasks in complex automation layouts.

2. Electrical Data

• Operating Voltage (Ub): 18…30 V DC (PELV / SELV compliant)

• Current Rating (Ie): 200 mA

• Electrical Design: DC PNP / NPN / Analog (Configurable multi-function outputs)

• Supply Type: Supply Class 2

3. Output Configurations & Modes

The sensor features two independent output options, customizable via parameters or IO-Link, as outlined in the wiring block diagrams on the label box:

Configuration Options:

• Digital Mode: Out 1 (Pin 4) and Out 2 (Pin 2) operate as switching thresholds (Normally Open / Normally Closed).

• Analog Mode: Out 2 (Pin 2) functions as a scalable analog tracking channel (Voltage or Current loop).

• Input (IN): Pin 5 functions as a dedicated external teaching or laser-off control input channel.

4. Mechanical & Environmental Data

• Housing Profile: Standard rectangular compact laser sensor assembly

• Ambient Operating Temperature: -10…60°C

• Ingress Protection (IP Rating): IP 67

• Country of Origin: Made in Germany

5. Electrical Connection & Wiring Layout

The sensor relies on a standard integrated M12 connector (5-pin configuration).

Pinout Assignment & Functions:

• Pin 1: Brown wire → L+ (18…30 V DC Power Supply)

• Pin 2: White wire → Out 2 (Switching output or Analogue out signal)

• Pin 3: Blue wire → -L (0 V Ground / Common)

• Pin 4: Black wire → Out 1 (Switching output or IO-Link data transmission channel)

• Pin 5: Gray wire → IN (Multi-function control input)
