Elevator & Automatic Door Safety Sensors
CEDES light curtains and time-of-flight sensors protect people at lift doors, automatic doors and industrial gates, from compact elevator curtains to SIL 2 certified door-edge sensors.
A door closing on a person is the most visible safety failure in a building. Sensors must detect reliably across the full door height, ignore passing traffic and survive constant cycling.
Types of elevator & door safety sensors
Elevator light curtains
Criss-cross infrared beams across the door opening for static or dynamic mounting, centre and side opening doors.
Models: Cegard/Mini · Easygard
SIL 2 door-edge sensors
TÜV-certified, SIL 2 light grids integrated directly into the door edge, for industrial and automatic doors.
Models: GridScan/Mini · GridScan/Mini-SB2-ST2 · GridScan/Pro
Time-of-flight sensors
Detection independent of reflectance, with adjustable detection areas and cross-traffic suppression for door activation and safeguarding.
Models: TOF/start · TOF/Start-EA · TOF niva · IMS 100 pro
Motion sensors
Compact door activation sensors with adjustable detection angle and wide detection area.
Models: RDS100
What to specify
| Parameter | What to check |
|---|---|
| Door type | Lift car/landing doors, automatic sliding or swing doors, or industrial gates. |
| Protection or activation | Light curtains and door-edge grids protect the closing edge; TOF and motion sensors open the door and monitor the area. |
| Safety level | For industrial and automatic doors where a certified function is required, use SIL 2 sensors (GridScan). |
| Mounting | Static (fixed frame) or dynamic (moves with the door); centre or side opening. |
| Traffic | Busy entrances benefit from cross-traffic suppression (TOF/start) to avoid unnecessary openings. |

Common questions
Light curtain or time-of-flight sensor: what's the difference?
A light curtain forms a plane of infrared beams across the door opening and detects anything that interrupts it. A time-of-flight sensor measures distance to everything in its field of view, so it can watch a 3D area, ignore cross-traffic and work independently of the object's reflectance.
What does SIL 2 mean for a door sensor?
SIL (Safety Integrity Level) rates the reliability of a safety function. SIL 2 certified sensors such as CEDES GridScan are TÜV-approved for door safety functions where a certified level of protection is required.
Static or dynamic mounting?
Static installations mount the sensor on the fixed door frame; dynamic installations mount it on the moving door. Cegard/Mini and Easygard support both; Easygard suits centre and side opening doors.
Can light curtains be retrofitted to older lifts?
Light curtains are commonly used to replace mechanical safety edges during modernisation. Share the door type, opening width and door controller details and we'll confirm a suitable model.
