Model: OLK 71 P3-T4

Part No.: 209974

---

1. General Description

 

The di-soric OLK 71 P3-T4 is a high-performance plastic fiber-optic amplifier. It is designed to be used with plastic fiber-optic cables (sold separately) for detecting objects in a wide variety of applications, especially in tight spaces or harsh environments where the amplifier must be mounted remotely.

This unit features a user-friendly interface with two 4-digit digital displays, showing both the setpoint (target value) and the current signal (actual value). It supports both simple Teach-in and fine manual adjustment for precise setup.

Key Features 🎯

 

• For Plastic Fiber-Optics: Designed for use with plastic (POF) fiber-optic cables.

• Dual Digital Display: Shows both the target value and actual value for easy setup.

• Precise Adjustment: Supports both “Teach-in” and fine manual adjustment.

• Selectable Switching: Can be switched between Light-on and Dark-on operation.

• Advanced Functions: Includes Time function and Offset function.

• PNP Output: Provides a standard 3-wire PNP (sourcing) output.

• Standard Connection: M8 4-pin connector for quick installation.
