EUSL-U30 Series T-Type Slot Photo Sensor
Dual-Channel Precision & Symmetric Stability – The Professional T-Type Slot Photo Sensor Choice for Center-Aligned Elevator Leveling & Industrial Automation.
Why Choose the T-Type Design?
Unlike standard U or L configurations, the T-Type Slot Photo Sensor features a center-mounted base that provides superior mechanical symmetry. This structural balance evenly distributes vibration stress, making it highly resistant to mechanical shocks in fast-moving machinery.
- Perfect for center-aligned guide rails
- Zero offset error during high-speed operation
- Saves lateral installation space

Key Performance Advantages
Dual-Channel Independent Output
Equipped with independent A/B optical axes. Dedicated Red/Yellow LED indicators allow engineers to monitor dual-way signals simultaneously without complex wiring.
1ms Ultra-Fast Response
With a maximum response time of 1ms, it eliminates signal lag, ensuring high-speed accuracy for counting, positioning, and elevator leveling in dynamic systems.
Advanced Optical Shielding
Integrated with a proprietary ASIC chip, it offers unique optical signal crosstalk shielding and extreme resistance to factory ambient light (up to 10,000 lx).
