Banner Engineering MB3-4 Photoelectric Logic Module

The MB3-4 Photoelectric Logic Module from Banner Engineering is the plug‑in logic module for Banner’s MULTI‑BEAM modular photoelectric sensors, designed to interconnect with a separate scanner block and power block to form a complete sensing solution. It provides the necessary timing logic between the blocks and can be configured for 3‑ or 4‑wire operation, including a light‑ or dark‑operate select. The module accepts the modulated signal from the scanner block and serves as the modulated amplifier logic stage, translating it into a clean, controllable output for downstream logic or actuators. Mechanical and electrical interconnection with the power block and scanner block is part of its standard design, enabling quick field replacement and flexible configurations. As part of the three‑component MULTI‑BEAM system (scanner block, power block, and logic module), MB3‑4 supports a compact, scalable approach for automation in packaging, material handling, and manufacturing lines where a programmable optical sensor is required.
