Frequently Asked Questions - SDBF-FES-1L-NU-K-N-M8 Festo
What is the Festo SDBF-FES-1L-NU-K-N-M8?
The Festo SDBF-FES-1L-NU-K-N-M8 is a magnetic field sensor designed for position sensing on pneumatic cylinders. It provides a reliable NPN output and is commonly used in automation systems.
Which cylinders is this sensor compatible with?
This sensor is compatible with T-slot pneumatic cylinders from Festo and other manufacturers that have a standard T-slot. The M8 connection simplifies installation.
How do I connect the SDBF-FES-1L-NU-K-N-M8?
Connect the M8 plug to a 3-pin M8 socket. Pin 1 is typically brown (supply), pin 2 is blue (ground), and pin 3 is black (switched output). Refer to the wiring diagram in the manual.
What is the output type and how does it work?
The sensor has an NPN transistor output that switches the supply voltage to the output line when a magnetic field is detected. It is normally open (NO), meaning the output is active only when the sensor is near a magnet.
What is the supply voltage range?
The device operates on a 10 to 30 V DC supply. It is suitable for standard PLCs and industrial control systems.
Does this sensor have an LED indicator?
Yes, an integrated status LED illuminates when the sensor is triggered, providing quick visual feedback during installation and operation.
What is the protection class of the sensor?
The sensor meets IP65 and IP67 standards, making it dust-tight and protected against temporary immersion in water, ideal for harsh industrial environments.
How do I install it in a T-slot cylinder?
Slide the sensor into the T-slot of the cylinder and adjust its position until it reliably detects the piston magnet. Tighten the fixing screw gently, avoiding overtightening to prevent damage.
Can I use this sensor with a PLC directly?
Yes, the NPN output can be connected to most PLC input modules. Ensure the PLC input is compatible with the NPN (sinking) configuration and respect the supply voltage range.
How should I clean and maintain this sensor?
Clean the sensor with a dry, lint-free cloth. Do not use solvents or abrasive cleaners. Regularly check the M8 connection for tightness and signs of damage.
