Delock 91868 Slot Sensor 5 mm Type F with 4 Open Cable Ends NPN L/D Switchable 2 m

The Delock 91868 is a high-precision 5 mm slot sensor, specifically designed as a Type F fork light barrier for reliable object detection in industrial environments. This sensor utilizes an NPN output configuration and offers the versatility of switchable Light-on and Dark-on (L/D) modes, allowing it to adapt to various operational requirements. Equipped with a 2-meter cable featuring four open ends, it provides significant flexibility for integration into diverse automation and control systems.

Advantages

The primary advantage of this slot sensor is its robust and compact design, which ensures consistent performance even in demanding industrial settings. The ability to switch between Light-on and Dark-on modes provides users with greater control over detection logic without needing to replace hardware. Furthermore, the inclusion of a 2-meter cable with open ends facilitates straightforward installation and customization, making it an ideal choice for engineers and technicians looking for a reliable, adaptable sensing solution for precise positioning or counting tasks.

Suitable for

• Industrial automation and assembly lines
• Object counting and presence detection
• Position monitoring in machinery
• Integration into custom control circuits

This sensor may not be suitable for applications requiring high-speed detection beyond its technical limits or in environments with extreme levels of ambient light interference that could overwhelm the optical path. It is also not intended for outdoor use without additional protective housing against moisture and extreme weather conditions.

Key specifications

• Slot width: 5 mm
• Sensor type: Type F fork light barrier
• Output type: NPN
• Switching modes: Light-on / Dark-on (L/D) switchable
• Cable length: 2 meters
• Connection: 4 open cable ends

To use the sensor, connect the four open cable ends to your control system or PLC according to the wiring diagram provided in the technical documentation. Ensure the power supply matches the required voltage specifications for the NPN output. Once connected, use the integrated switch to select the desired Light-on or Dark-on mode based on your specific detection logic. The sensor is ready for operation immediately upon proper installation and alignment within the slot.

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 NPN output signals.
• Confirm that the 2-meter cable length is adequate for your installation layout.
• Check the environmental conditions to ensure they fall within the sensor's operating parameters.

For optimal performance, ensure the sensor is mounted securely to prevent vibrations from causing false triggers. Regularly clean the optical surfaces of the slot to maintain detection accuracy and prevent dust accumulation.
