Overview
The Allen-Bradley 800Z-GF3 is a zero-force touch button from the acclaimed 800Z series of touchless pushbuttons. Zero-force touch technology eliminates the need for physical pressure to activate, providing consistent operation and reduced operator fatigue. Designed specifically for two-hand control systems, this touch button features an interlinked capacitive sensor surface that detects hand presence even through most industrial gloves, making it essential for safety-critical machine control applications.
Key Features
- Capacitive sensing technology with dual offset-plane sensors for enhanced sensitivity
- Zero-force actuation—no physical pressure required to activate the button
- Hand-conforming contour design prevents accidental bypass in two-hand control mode
- Works through industrial gloves and protective equipment
- Coil voltage range: 100-240V AC/DC for flexible integration
- Series C construction with industry-standard certifications (UL 508, CSA 22.2 No. 14, EN/IEC 60947-5-1)
- Quick-disconnect terminal configuration for field serviceability
