## Long description

The Delock 91866 is a high-precision L-type slot sensor designed for reliable object detection in industrial and technical environments. Featuring a 5 mm slot width, this sensor utilizes an infrared light beam to detect objects passing through the gap. It is equipped with four open cable ends for flexible integration into existing control systems and supports NPN output with a switchable light-on or dark-on (L/D) operation mode, allowing for versatile configuration based on specific application requirements.
Advantages
This slot sensor offers exceptional reliability due to its non-contact detection method, which minimizes mechanical wear and ensures long-term operational stability. The L-shaped design allows for easy mounting in tight spaces where standard sensors might not fit. With its switchable L/D functionality, users can easily adapt the sensor output to trigger either when an object is present or when the beam is clear, providing significant flexibility for automated processes. The 2-meter cable length offers sufficient reach for most standard industrial setups, reducing the need for additional extensions.
Suitable for
Industrial automation and assembly lines
Precise position sensing of mechanical parts
Counting objects on conveyor belts
Detection of edge positions or labels
This sensor may not be suitable for environments with extremely high levels of ambient light interference or where the target object is smaller than the 5 mm slot width. It is also not intended for outdoor use without additional protective housing, as it is not specified for extreme weather conditions or high-pressure cleaning environments.
Key specifications
Slot width: 5 mm
Output type: NPN
Switching mode: Light-on / Dark-on (L/D) switchable
Cable length: 2 m
Connection: 4 open cable ends
Design: L-type
To use the Delock 91866, connect the four open cable ends to your PLC or control unit according to the wiring diagram provided in the technical documentation. Ensure the sensor is securely mounted so that the object to be detected passes cleanly through the 5 mm slot. Once powered, use the integrated switch to select between light-on or dark-on mode depending on whether you need the signal to trigger when an object enters the slot or when it leaves it.
What to consider before purchase
Verify that the 5 mm slot width is sufficient for your target objects.
Ensure your control system is compatible with NPN output signals.
Check if the 2-meter cable length is adequate for your installation distance.
Confirm the mounting space allows for the L-type form factor.
For optimal performance, keep the optical surfaces of the slot clean and free from dust or debris. Regularly inspect the cable connections to ensure they remain secure and protected from mechanical stress or vibration.
