Festo SME Series Slot-Style Proximity Sensor, Bipolar, Contacting Output, 12 → 30 V, IP65, IP67

The Festo SME-8-K-7,5-LED-24 is a slot-style proximity sensor used to detect piston position in pneumatic cylinders. It is typically installed in automation systems where knowing the exact end position of a cylinder matters for timing, safety, or sequence control. The sensor operates on a 12 to 30 V supply and provides a bipolar contacting output that works with a wide range of control inputs. This model is designed for everyday industrial use, not special or fragile environments. It focuses on dependable switching rather than advanced diagnostics.

Unmatched Advantages of Investing in the Festo SME-8 Slot-Style Proximity Sensor

The sensor mounts directly into the cylinder slot and detects the piston's magnetic field. When the piston reaches the sensing point, the LED indicator clearly shows the switching state, making setup and troubleshooting easier during installation.

• Consistent detection of piston movement.
• Clear LED status indication.
• Stable switching without signal fluctuation.
• Bipolar contacting output.
• Slot-style mounting.
• Fixed cable connection.
• LED switching indicator.

Electrical and Mechanical Characteristics

The SME-8-K-7,5-LED-24 supports bipolar contacting output, allowing it to work with both PNP and NPN control logic depending on the wiring. This makes it flexible for use in mixed control cabinets or older systems.

Product Use Cases

This sensor is typically found in:

• Pneumatic cylinders on assembly lines
• Packaging and material handling systems
• Conveyor and actuator position monitoring
• General factory automation setups
