Frequently Asked Questions - SDBT-MSB-1L-NU-K-2-LE Festo

What is the Festo SDBT-MSB-1L-NU-K-2-LE used for?

It is a magnetic proximity sensor used to detect the position of a piston in pneumatic cylinders by sensing the magnetic field of the piston magnet.

What is the operating voltage range?

The sensor operates on 10-30 V DC. Ensure your power supply is within this range.

What output type does this sensor have?

It has an NPN, Normally Open (NO) output. When a magnetic field is detected, the output switches to low (sinking).

How is the sensor connected?

It comes with a 2-meter cable, 2-wire. Connect the brown wire to positive supply and the blue wire to the load/ground.

Can this sensor be mounted on any cylinder?

It is designed for T-slot mounting typically found on Festo cylinders. Ensure your cylinder has a compatible T-slot profile.

What is the switching frequency?

The maximum switching frequency is 1000 Hz, suitable for high-speed applications.

Is the sensor protected against water and dust?

Yes, it has IP67 protection when the cable and connector are properly sealed.

How should I clean the sensor?

Wipe gently with a dry, soft cloth. Do not use chemicals or submerge in liquids.

What does the LED indicator mean?

The LED illuminates when the sensor output is active (magnetic field detected). It helps with alignment and troubleshooting.

Can this sensor be repaired?

No, the sensor is non-repairable. If it malfunctions, replace it with a new unit.
