C-slot proximity sensor with PNP N/O output. IP67/IP68 rated, oil-resistant, and features a 0.3m M8 pigtail cable for rapid connectivity.
The Festo 8139726 (Model SDBC-MSB-1L-PU-K-0.3-M8) is a highly reliable magneto-resistive proximity sensor engineered for accurate contactless position detection in industrial automation. Specifically designed to integrate seamlessly into pneumatic cylinder C-slots, this solid-state sensor provides a 3-wire PNP normally-open (N/O) switching output. It operates efficiently on a 10 to 30 V DC supply (24 V DC nominal) and includes a highly visible LED indicator for fast setup and status monitoring. Built to withstand demanding manufacturing environments, it boasts IP67 and IP68 protection ratings along with an oil-resistant cable suitable for continuous flexing in energy chains. The sensor features a 0.3-meter pigtail cable terminated with an industry-standard 3-pin M8x1 plug, ensuring rapid and secure electrical connectivity.

Integrated directly into the C-slots of Festo parallel or adaptive grippers (such as the DHPL or HPPF series) to detect the exact open or closed position of the jaws.
Provides the PLC with exact real-time confirmation that a workpiece is securely grasped or released, preventing robotic arms from moving prematurely and avoiding dropped parts.
Utilized in high-speed packaging or pick-and-place gantry systems where sensor cables must be routed through flexible, fast-moving cable carriers.
Standard PVC sensor cables often degrade or snap under continuous flex fatigue. This sensor's specialized cable rating ensures long-term electrical integrity through millions of dynamic flex cycles.
Deployed on linear pneumatic actuators operating near CNC milling enclosures where industrial cutting fluids, lubricants, and washdowns are prevalent.
Mechanical limit switches frequently fail or jam due to fluid and particulate ingress. The IP67/IP68 rating combined with oil-resistant cabling ensures uninterrupted, wear-free sensing even when continuously exposed to harsh machining environments.
