The Schneider Electric MTN6355-0019 is a KNX corridor presence detector for indoor ceiling mounting at 2.5–5 m height. Its elongated detection field (up to 20 × 4 m lateral) suits hallways, hospital corridors, and hotel passages better than circular room sensors.

Surface-mount variant of the corridor platform (flush-mount sibling MTN6305-0019). Creep zone protection, twilight teach-in, and dual-light outputs integrate with KNX actuators and room controllers on the same line.

Key Features — Corridor Presence Detector

• Detection geometry: Optimised for long, narrow spaces (arrow on lens indicates corridor axis).
• Range: Up to 20 × 4 m lateral; 360° / 180° aperture PIR.
• Mounting height: 2.5–5 m.
• Switching zones: Up to 280 (ETS).
• Protection: IP54 surface; −20 °C to +50 °C.

Choosing Corridor vs Room Detectors

Select MTN6355-0019 when the detection field must follow a corridor axis. For open-plan offices with 360° room coverage, use MTN6300-0019 or MTN630819.
