Festo 150853, model SME-3-SL-LED-24-B, is a compact magnetic proximity sensor designed for clamping into a dovetail slot on compatible pneumatic actuators. Using a reed magnetic measuring principle, it provides a bipolar, normally open contact output with a yellow LED for clear operating-status indication. The sensor operates from 12–27 V DC and features a 3-pin M8x1 plug for straightforward electrical connection. Its die-cast magnesium housing and IP66 protection rating suit demanding industrial automation environments, while switching-value reproducibility of ±0.1 mm supports consistent position detection.

What type of sensor is this component?
It is a magnetic proximity sensor designed to detect the position of a moving pneumatic cylinder piston without direct mechanical contact.
What sensing principle does this proximity sensor use?
The sensor uses a reed magnetic measuring principle, switching when it detects the magnetic field generated by a compatible cylinder piston.
How is the sensor mounted?
It is clamped into a compatible dovetail slot, allowing it to be positioned at the required switching point along the cylinder.
What operating voltage does it require?
The sensor operates from a 12 to 27 V DC supply.
What type of electrical connection is provided?
Festo 150853 has a three-pin M8x1 plug connection.
What is the switching function?
It has a normally open contact with a bipolar contact output. The circuit closes when the relevant magnetic field is detected.
Does the sensor include an operating status indicator?
Yes. A yellow LED provides a visual indication of the sensor's operating or switching status.
What environmental protection rating does it have?
The proximity sensor is rated IP66, indicating protection against dust ingress and powerful water jets when correctly installed.
What ambient temperature range is suitable?
It is specified for operation in ambient temperatures from -20°C to 60°C.
What is the maximum output current?
The specified maximum output current is 500 mA.
What is the maximum DC contact rating?
The maximum specified DC contact rating is 10 W.
How quickly does the sensor switch?
The switch-on time is no more than 0.5 ms, while the specified switch-off time is 0.03 ms.
How repeatable is the switching position?
The switching value has a stated reproducibility of ±0.1 mm, supporting consistent piston-position detection.
Is the sensor protected against incorrect polarity or short circuits?
No. The specification states that it is neither polarity protected nor short-circuit resistant, so the electrical connections and load limits must be checked carefully during installation.
What material is used for the housing?
The housing is made from die-cast magnesium, providing a compact and robust enclosure.
What applications is this sensor commonly used for?
It is commonly used to detect extended, retracted or intermediate piston positions on compatible pneumatic cylinders with dovetail mounting slots.
- Detecting piston position in pneumatic cylinders with dovetail mounting slots
- Confirming cylinder extension and retraction in automated machinery
- Providing end-of-stroke feedback in pneumatic handling systems
- Monitoring actuator movement on production and assembly lines
- Triggering sequential operations within pneumatic control systems
- Supporting workpiece positioning in pick-and-place equipment
- Indicating actuator status through an integrated yellow LED
- Detecting magnetic piston movement in packaging machinery
- Providing switching signals for material handling and conveyor applications
- Monitoring compact pneumatic actuators in factory automation equipment
