Description
The D4DS-K1, D4NS, and D4NS-SK are a comprehensive range of safety interlock switches and accessories designed for safeguarding access points in industrial machinery. This “New Generation” series is known for its multi-contact configurations, labor-saving features, and environmentally friendly design. The D4NS series is the main switch body, the D4DS-K1 is a horizontal-mounting operation key (actuator), and the D4NS-SK is a slide key unit. These components are engineered to prevent accidental machine start-up when guards or doors are open, ensuring operator safety.
Key Features
- Multi-Contact Configurations: Available in 1NC/1NO, 2NC, 2NC/1NO, and 3NC contact forms for versatile safety circuit design.
- Labor-Saving Installation: M12 connector models are available for quick and easy replacement, reducing downtime.
- Direct Opening Mechanism: Certified direct opening contacts ensure a positive mechanical disconnection for high safety integrity (EN 60947-5-1).
- High Reliability: Standardized gold-clad contacts provide high contact reliability and are suitable for both standard loads and micro loads.
- Environmentally Friendly: Free of lead, cadmium, and hexavalent chrome, reducing the environmental burden.
- Versatile Mounting: D4NS head can be mounted in four directions, and operation keys (D4DS-K1) are designed for horizontal mounting applications.
