Safety Non-Contact General 1-2-Opto-electronics 3-Interlock Logic Description When it comes to machine safety, Rockwell Automation knows that protection of personnel and equipment is your main concern. At the same time, flexibility and productivity are points that must also be considered as you design your safety system. Optimize all of these with the new Allen-Bradley family of non-contact switches. Featuring the latest generation of RFID technology for coding and inductive technology for sensing, s large sensing range and tolerance to misalignment is a cost-effective solution that is ideally suited for a wide range of industrial safety applications. The product line is a Category 4/SIL 3 rated switch per EN954-1, TÜV functional safety approved to IEC 6158. Features can be connect to a standard safety relay, for example, the MSR126, MSR127, MSR/ Family, SmartGuard and Safety I/O Blocks Multiple actuator sizes for large sensing distance IP69K environmental rating Short-circuit and over-voltage protection LED located on the switch for door status and troubleshooting Unique coded version Automatic learn process at unit power up During commissioning you have the option to select if the sensor can learn a new actuator up to eight times or lock the unit so it can not learn another actuator Integrated latch version Adjustable magnetic latch force 6N Designed for easy mounting on aluminum profile Benefits No dedicated controller required Cat 4/SIL 3 rating maintained even with multiple units connected in series can be connected in series with other devices (light curtain, E-stops, key interlock switches) Extended diagnostics for easy troubleshooting Large sensing distances Tolerance to misalignment Multiple sensing directions Stainless steel version suitable for use in harsh environments Use standard proximity brackets Specifications Safety Ratings Standards IEC 6947-5-3, IEC 6158, EN 954 Safety Classification Functional Safety Data Note: For up-to-date information, visit http://www.ab.com/safety/ Certifications Cat. 4/SIL3 Outputs (Guard Door Closed, Actuator in Place) Safety Outputs Auxiliary Outputs Operating Characteristics Sensing (Assure) Misalignment Tolerance, Min Repeat Accuracy Output Current, Max.
