1. Product Overview and Technical Specifications
The Pilz PSEN cs3.1 is a compact, electromechanical safety switch designed for guarding doors and access points in industrial machinery. It complies with ISO 14119 and SIL 3/PLe safety standards, offering reliable protection against accidental machine starts. The switch operates with a coded actuator (PSEN cs1.1), ensuring secure mechanical locking and monitoring. With a robust metal housing (IP67 rating), it withstands harsh environments, including dust, moisture, and vibrations. The PSEN cs3.1 features dual-channel NC/NO contacts (2 safety outputs + 1 auxiliary signal) for integration into safety circuits. Its simple plug-and-play design reduces installation time, while a diagnostic LED provides real-time status feedback. The device supports voltages from 24 VDC to 230 VAC, making it adaptable to diverse control systems.
2. Functional Benefits and Application Scenarios
This safety switch is ideal for applications requiring high-integrity access control, such as robotic cells, press brakes, and automated assembly lines. Its tamper-resistant design prevents bypassing, ensuring compliance with machinery directives like EN ISO 13849-1. The PSEN cs3.1’s short reset time minimizes downtime during door cycling, while its integrated locking mechanism holds doors securely until machinery halts safely. In food and pharmaceutical industries, the stainless-steel variants resist corrosion from frequent washdowns. Compatibility with Pilz’s PNOZsigma safety relays and configurable logic controllers (PLCs) enables scalable safety solutions. Users benefit from reduced maintenance due to its mechanical durability (>1 million operations) and self-cleaning contacts.
3. Compliance and Integration Capabilities
Certified globally (CE, UL, CSA), the PSEN cs3.1 meets stringent safety requirements for global markets. Its modular design allows integration with Pilz’s SafetyEye vision systems or PASconfig software for centralized safety management. The switch supports PROFIsafe and CIP Safety protocols for seamless communication in Industry 4.0 networks. Optional RFID coding ensures actuator-switch pairing accuracy in multi-door setups. Pilz’s diagnostic tools, like PASvisu, enable predictive maintenance by tracking switch performance metrics. With customizable actuator lengths (up to 40 mm) and mounting brackets, it adapts to complex door geometries. The PSEN cs3.1 exemplifies Pilz’s commitment to safety innovation, combining simplicity with advanced risk mitigation for modern automated environments.
