Technical Overview

The Festo 8150173 (Model: SDBT-MSB-1L-ZU-K-2-LE) is an advanced solid-state magneto-resistive proximity switch engineered for highly precise position sensing on T-slot pneumatic cylinders. Utilizing a non-contacting, 2-wire normally open (N/O) digital switching output, it provides rapid response times (≤ 2.5 ms) and superior repeatability (0.2 mm) for demanding industrial automation setups. Operating at a nominal 24 V DC, the sensor features an integrated 2-meter cable specifically designed to withstand continuous dynamic flexing in energy chains. Designed with extreme environmental resilience, it is certified to IP65 and IP68 standards for liquid and dust ingress protection. Furthermore, its halogen-free, copper-free, and oil-resistant construction ensures compliance with Cleanroom Class 4 (ISO 14644-1) and renders it highly suitable for sensitive lithium-ion battery manufacturing environments.

Key Features

  • Solid-state magneto-resistive measuring principle provides infinite operational lifespan and wear-free position detection.
  • Non-contacting 2-wire N/O switching output for streamlined electrical integration with industrial controllers.
  • Highly flexible 2-meter open-end cable explicitly rated for use in dynamic robotic energy chains.
  • Maximum ingress protection (IP65/IP68) guarantees continuous performance in wet or washdown conditions.
  • Cleanroom Class 4 (ISO 14644-1) certified design, ensuring negligible particle emission in sterile environments.
  • Copper, zinc, and halogen-free construction optimizes the sensor for zero-contamination Li-ion battery manufacturing.
  • Rapid switch-on and switch-off times (≤ 2.5 ms) paired with a high repetition accuracy of 0.2 mm.

Industrial Applications

1. Lithium-Ion Battery Cell Handling and Assembly

Standard pneumatic sensors can introduce microscopic conductive particulates (such as copper or zinc), which pose a severe risk of internal short circuits in battery cells. This Festo sensor monitors the stroke limits of pneumatic grippers handling raw electrodes and cell housings.

Problem Solved

Eliminates particulate contamination. The completely copper-free and zinc-free composition ensures 100% compliance with strict battery manufacturing specifications, preventing catastrophic cell degradation.

2. High-Speed Gantry Robotic Packaging Systems

In rapidly moving end-of-line packaging lines, sensors mounted on pneumatic ejectors and pushers require constant movement. The proximity switch is routed through complex, fast-moving robotic gantries to track the actuator position.

Problem Solved

Prevents electrical continuity loss due to mechanical fatigue. The specialized energy chain-rated 2-meter cable is built to endure millions of sharp flexing cycles without breaking or dropping the 24 V DC signal.

3. Pharmaceutical Clean-in-Place (CIP) Dosing Stations

Sterile liquid filling environments require frequent high-pressure washdowns and chemical sanitization. This sensor tracks the extension of T-slot pneumatic dosing cylinders that actuate sterile filling valves.

Problem Solved

Defeats fluid ingress failures. The industrial-grade IP65/IP68 rating guarantees absolute watertight integrity during chemical washdowns, while the ISO 14644-1 Class 4 certification supports strict aseptic cleanroom mandates.
