Leuze lumiflex has extended its delivery range of safety sensor technology with the integrated PROFIsafe interface. In addition to the type 3 safety laser scanner, RS4-4/PROFIsafe, a type 4 safety light curtain with integrated PROFIsafe interface is now also available with the COMPACTplus/PROFIsafe. The PROIBUS DP bus activation is performed here directly and without additional bus coupling modules. With a data transfer rate of up to 12 MBd, both the safe cyclic and the acyclic data traffic are supported on the PROFIBUS DP. Rapid safety-relevant real-time data, such as a switch-off command when operating the sensor and comprehensive diagnostics data with the controlling PLC, for example, can consequently be exchanged. COMPACTplus/PROFIsafe meets the requirements of SIL 3 in accordance with IEC 61508 and is available with the blanking, muting and cycle control function packages. The individual adjustment of the functions is performed via the optical PC interface of the receiver with “teach-in” and with the aid of the convenient diagnostics and parametering software, SafetyLab.

The SB2-K-2-500 safety barriers has been developed for applications which require the detection of the human body; it is a low resolution system with 2 beams placed with an optic interaxis of 500 mm. The optic interaxis is compliant to the requirements of the EN 999 Regulation.
It is possible to realise barriers with height and number of beams changeable, according to the specific uses and requirements. Thanks to the small size, the easiness of installation and the high performances, the product is extremely versatile. The control and command electronics are inside the barrier; connections are made through a connector positioned under the barrier. No connection is necessary between the emitter and receiver, thanks to the optical type synchronism. The control of the emitted and received beams is guided by the two microprocessors that, by means of signalling LEDs, also supply information on the barrier's operating status. The installation is facilitated thanks to two alignment LEDs.
