OTIS Photoelectric Leveling Switch DAA629F2 Elevator Door Safety Interlock Sensor with Precise Floor Position Detection

OTIS Photoelectric Leveling Switch DAA629F2

The OTIS DAA629F2 is a photoelectric leveling sensor serving dual functions: precise floor leveling position detection and door safety interlock control. It detects the leveling vane at each floor and sends real-time position signals to the mainboard while interlocking with door circuits for passenger safety.

Key Features

• Dual Safety Function: Combines precise floor leveling (±1mm) and door safety interlock in a single sensor unit
• Door Interlock Control: Prevents doors from opening until full leveling is confirmed, eliminating fall hazards
• Real-Time Position Feedback: Continuous position signal transmission during approach, leveling, and door zones
• Fail-Safe Design: Normally-closed safety circuit ensures doors remain locked if sensor malfunctions
• OTIS System Integration: Direct plug-in replacement for OTIS elevator leveling and door safety systems
