Technical Overview

The Festo SDBT-MSB-1L-PU-K-2-LE (Part Number: 8150171) is a magneto-resistive proximity switch designed for position measurement on pneumatic actuators with T-slots. It provides a PNP switching output with a 3-wire normally open (N/O) contact. Operating on a 10 to 30 VDC range, it delivers fast position sensing with a maximum switching frequency of 480 Hz and a repetition accuracy of 0.2 mm. Engineered for harsh environments, the housing is rated IP67 and IP68 according to IEC 60529. It features a 2-meter polyurethane (PUR) open-ended cable that is suitable for energy chains. Furthermore, the sensor is certified for LABS (PWIS) conformity and is suitable for lithium-ion battery manufacturing due to its reduced Cu/Zn/Ni content.

Industrial Applications

1. End-of-Stroke Sensing in Lithium-Ion Battery Assembly Systems [2.3]

In battery cell manufacturing lines, precision pneumatic positioning is critical. Contamination risks from metals must be minimized to avoid rendering battery cells unusable. This sensor mounts directly into actuator T-slots, providing highly accurate verification without exposing the battery materials to hazardous metals.

Problem Solved

Eliminates the risk of cell contamination during pneumatic positioning by using a sensor certified with reduced Cu/Zn/Ni content, while maintaining high-speed position feedback.

2. Automated Packaging Machinery in Washdown Environments

Packaging lines frequently require washdown protocols, exposing components to fluid ingress. Installed on T-slot pneumatic cylinders, this proximity switch accurately signals when mechanical flaps are fully actuated.

Problem Solved

Prevents sensor failure caused by fluid ingress during heavy washdown cycles, relying on its IP67 and IP68 ingress protection ratings and its durable PUR cable jacket.

3. High-Speed Robotic Gripper Verification

Robotic arms handling discrete components frequently utilize parallel pneumatic grippers, such as the Festo DHPL series. By integrating the SDBT-MSB sensor directly into the gripper's T-slot, the controller receives immediate feedback confirming a successful grasp.

Problem Solved

Ensures secure and verified grasping in high-throughput robotics. Its 0.2 mm repetition accuracy and extremely fast 2.5 ms response time enable tight cycle times without controller misreads.
