ABB MLBL-07Y Industrial Magnetic Limit Switch

ABB MLBL-07Y is a yellow, integrated LED indicator block designed for ABB’s 22 mm pilot devices, providing a built-in illumination module that signals the status of a machine on control panels. It operates from 230 V AC and is engineered to mount with ABB’s modular 22 mm pilot systems, including compatibility with the 1SFA61 family of pilot devices, enabling color-coded indicators without separate lamps. This MLBL LED block is part of ABB’s MLBL lineup, designed to drop into the same 22 mm housing as other color variants such as MLBL-07R (red) and MLBL-07G (green) to support quick visual cues for operators and maintenance staff. By integrating the lamp directly into the pilot device ecosystem, the MLBL-07Y simplifies wiring and replacement while delivering a durable, compact indicator solution for industrial panels.
