Master 1124-NEOPA.1 Chain Actuator Concealed 24V DC 250N Selectable Stroke Black

Product Overview

The Master Apro 24V DC Concealed Chain Actuator (1124-NEOPA.1) is a hidden window actuator designed for automating tilt windows in residential, commercial, and industrial buildings. It operates on 24V DC power, provides a maximum force of 250 N, and features a selectable chain stroke of 100, 160, or 210 mm. Its slim profile (325x24x27 mm) allows installation recessed within the window sash, preserving the window's design aesthetic and supporting integration with modern building automation systems. Rated at IP32 and suitable for operation from -5°C to +65°C, it meets requirements for both ventilation and smoke extraction scenarios.

The actuator?s invisible integration within the window sash is its standout feature, addressing architectural requirements for clean lines and unobtrusive automation in high-specification projects. This minimizes design compromise and reduces installation complexity, as the unit does not alter window appearance. Particularly well-suited for window manufacturers, system integrators, and B2B procurement for modern residential and office projects requiring automation without visible hardware.
