Technical Datasheet: ifm OK5008

Model/Type: OKF-FPKG

1. Product Characteristics & Application

• Sensor Type: Photoelectric Sensor / Fiber Optic Amplifier

• Housing Design: Rectangular compact block profile

• Sensing Range: Dependent on the connected glass or plastic fiber optic cable assembly.

• Special Features: Integrated optical interface for fiber connection (visible on the front face next to the label plate). Highly versatile setup for object detection in extreme temperatures, high vibrations, or space-critical points.

2. Electrical Data

• Operating Voltage (U): 10…55 V DC

• Current Consumption: < 35 mA

• Electrical Design: DC PNP

• Output Function: Light-ON or Dark-ON (Selectable via connection terminal pin 2 settings)

• Reverse Polarity Protection: Yes

3. Outputs

• Permanent Current Rating (I): 250 mA (High switching current load handling)

• Short-Circuit Protection (SCP): Yes

• Overload Protection: Yes

4. Operation Mode Selection (Pin 2 Configuration)

The output operation mode is dynamically determined by how Pin 2 is connected to the supply circuit as specified on the sensor label:

• Light-ON Mode: Connect Pin 2 to L- (0 V Ground)

• Dark-ON Mode: Connect Pin 2 to L+ (+V DC)

5. Mechanical & Environmental Data

• Housing Material: Robust PBT plastic housing

• Ambient Operating Temperature: -25…60°C

• Ingress Protection (IP Rating): IP 65

• Country of Origin: Made in Germany

6. Electrical Connection & Wiring Layout

The sensor utilizes an integrated standard thread connector head (typically standard M12 or M8 multi-pin layout).
