Sick deTec2 Safety Light Curtain Responds to the Latest PL and SIL Requirements
Following the launch of the deTec4 Core, which is certified for PL e or SIL3, Sick are now offering a type 2 device with PL c or SIL1. The deTec2 Core boasts state-of-the-art technology and accommodates the changes to product standard IEC 61496-1.
The revised IEC 61496-1 product standard has “learned” from the past. One key change concerns the relationship of performance levels (PL) and the safety integrity level (SIL) to a suitable protective device type. Type 2 safety light curtains are permitted for the protection of machines up to performance level c/SIL1. Should a risk assessment reveal that safety level PL d/SIL2 is required, then the latest technology has been available for almost a year.
The revised version of IEC 61496-1 helps you to select an electro-sensitive protective device with ease and it also precisely states that for applications according to PL d/SIL2, only type 4 safety light curtains and thereby the next highest protection category can be employed. Alternatively, other than scanners, safety camera systems are the only optical protective devices available on the market which correspond exactly to the SIL2/PL d safety level.
deTec2 Core: when the core objective is safety and easy handling
The deTec2 Core brings pure safety for the machine and operator to reality – with the ultimate in simplicity for the integrator and machine operator: externally, the deTec2 Core boasts a rugged, distinct design. The 4-pin connection technology enables rapid cabling or connection to bus systems, such as Flexi Loop from SICK. With IP 65 and IP 67 enclosure ratings and an operating temperature range of –30°C to +55°C, the safety light curtain is also ideal for use in challenging environments. During the development of the new deTec safety light curtains, SICK’s priority was to ensure that they could be quickly and easily mounted.
