Product catalog summary
Product Introduction
The SSR21 Series is a contactless safety door switch designed to monitor the open/close status of movable mechanisms such as safety fence doors and protective covers. It utilizes RFID technology for enhanced security and confidentiality. The sensor and actuator can be matched with universal or unique coding, and its small size facilitates easy installation.
Product Features
The SSR21 Series includes self-diagnose and cross-diagnose capabilities with periodic dual mutual-diagnose to improve safety. It features independent redundant dual output to mitigate potential safety hazards from single loop failures.

Standards and Compliance
The product complies with ISO 13849-1 (Cat. 2/PL c) and IEC/EN60947-5-3 standards.
Model Selection
The SSR21 Series offers various configurations based on coding mode (universal or unique), output type (NPN or PNP), and cable length. Models include SSR21-00N, SSR21-01N, SSR21-00P, SSR21-01P, SSR21-10N, SSR21-11N, SSR21-10P, and SSR21-11P.
Indicator Status
The switch status is indicated by different light patterns, such as red or green blinks, to denote errors or normal operation.
Wiring Diagrams
Detailed wiring diagrams are provided for both NPN and PNP configurations, illustrating connections for power supply, safety outputs, and inputs.
