Leuze electronic MLC 530 11
3 Device description
The safety sensors from the MLC 500 series are active opto-electronic protective devices. They satisfy the
following standards:
The safety sensor consists of a transmitter and a receiver (see figure 3.1). It is protected against over-
voltage and overcurrent acc. to IEC 60204-1 (safety class 3). Its infrared beams are not influenced by
ambient light (e.g. welding sparks, warning lights).
3.1 Device overview
The series is characterized by three different receiver classes (Basic, Standard, Extended) with certain
features and properties (see table 3.1).
Table 3.1: Device models in the series with specific features and functions
Protective field properties
The beam distance and the number of beams are dependent on the resolution and protective field height.
