Installation Guide
First, insert the sensor into the T-slot from above. Then, tighten the screw to 0.6 Nm. Next, connect the M8 plug. After that, check the yellow LED. Finally, keep the cable bend radius at 28 mm or more for chain use.
Debugging and Maintenance Convenience
Therefore, this sensor needs little care. The yellow LED shows output status. Also, the orange LED shows operating reserve. Moreover, the sealed housing resists dust and water. In addition, the M8 plug makes swaps fast. Furthermore, the high IP rating allows washdown cleaning. Finally, the oil-resistant cable lasts long in machine shops.
Compatibility Notes
First, it fits standard T-slots on Festo cylinders. Second, it works with any 24 V DC PNP input card. Also, it suits PLCs, valve terminals, and motion controllers. Moreover, the M8 3-pin plug matches common industrial cables. Consequently, it drops into most automation setups. In short, it is a flexible choice for cylinder feedback.
