## Summary description

The Delock 91871 is a 5 mm slot sensor (Type R) designed for precise object detection in industrial automation. It features a 2-meter cable with 4 open ends, supports PNP switching output, and offers selectable Light-on/Dark-on (L/D) modes. This reliable photoelectric sensor is ideal for position sensing, counting applications, and motion control systems requiring high accuracy and consistent performance in various technical environments.

## Long description

The Delock 91871 is a high-precision 5 mm slot sensor, specifically engineered as a Type R photoelectric sensor for industrial automation and control systems. This device provides reliable object detection by utilizing an infrared light beam within its 5 mm slot, making it an essential component for automated machinery where accuracy and consistency are paramount. The sensor is equipped with a 2-meter cable featuring four open ends for flexible integration into existing electrical circuits, and it supports PNP switching output with user-selectable Light-on or Dark-on operating modes.
Advantages
This slot sensor offers exceptional reliability due to its non-contact detection method, which minimizes mechanical wear and ensures a long operational lifespan. The ability to switch between Light-on and Dark-on modes provides significant versatility, allowing the sensor to be adapted to various logic requirements without needing additional hardware. Its compact design and integrated 2-meter cable facilitate straightforward installation in tight spaces, while the PNP output configuration ensures compatibility with a wide range of industrial controllers and programmable logic controllers.
Suitable for
Position sensing in automated assembly lines
Counting objects on conveyor belts
Motion control and limit detection in robotics
Edge detection for thin materials
This sensor may not be suitable for applications involving highly reflective or transparent objects that could interfere with the infrared beam. Additionally, it is not intended for outdoor use or environments with extreme levels of ambient light interference or heavy dust accumulation that could obstruct the optical slot.
Key specifications
Slot width: 5 mm
Sensor type: Type R photoelectric slot sensor
Output type: PNP
Switching modes: Light-on / Dark-on selectable
Cable length: 2 meters
Connection: 4 open cable ends
To use the Delock 91871, connect the four open cable ends to your control system according to the wiring diagram provided in the technical documentation. Ensure the power supply matches the voltage requirements of the sensor. Once connected, select the desired switching mode (Light-on or Dark-on) using the integrated switch. Position the sensor so that the object to be detected passes through the 5 mm slot, ensuring the beam is interrupted consistently.
What to consider before purchase
Verify that the 5 mm slot width is sufficient for the objects you intend to detect.
Ensure your control system is compatible with PNP output signals.
Confirm that the 2-meter cable length is adequate for your installation layout.
Check the environmental conditions to ensure they are within the operating limits of the sensor.
Usage recommendations: Regularly clean the interior of the optical slot with a soft, dry cloth to prevent dust or debris buildup, which can lead to false triggering or signal loss. Ensure the sensor is securely mounted to prevent vibrations from affecting detection accuracy.
