Assa Abloy - SC53-M, IXIO DT1

Assa Abloy – SC53‑M / IXIO‑DT1 Dual‑Technology Door Sensor

The Assa Abloy SC53‑M / IXIO‑DT1 is a high‑performance dual‑technology activation and safety sensor for automatic sliding doors. Combining microwave radar for activation with active‑infrared curtains for presence protection, it provides fast, reliable detection while ensuring maximum pedestrian safety.

Ideal for commercial, healthcare, retail, and public buildings, this sensor delivers precise detection, user protection, and efficient door operation.

Key Features & Benefits

• Dual‑Technology Detection
  Uses microwave radar to detect motion approaching the door and active‑infrared curtains to protect users standing in the threshold or near the side‑lites.

• Activation + Safety in One Device
  Eliminates the need for separate activation and presence sensors, reducing installation time and simplifying maintenance.

• Adjustable Infrared Curtains
  Two high‑density IR curtains provide accurate presence monitoring to prevent the door from closing on pedestrians or obstructions.

• Energy‑Efficient Activation
  Radar field can be set for unidirectional detection to reduce unnecessary door cycles, helping minimise heat loss and improve building efficiency.

• On‑Board LCD Display
  Built‑in screen allows quick setup, alignment, and fine‑tuning without specialised tools.

• Self‑Monitoring Safety
  Supports monitored safety inputs and outputs, making it suitable for EN16005‑compliant installations.

• Robust and Reliable
  Designed for long‑term use in high‑traffic environments and suitable for indoor or sheltered outdoor use.
