Product description
3.2 Operating principle of the device
3.2.1 Components of the device
Please refer to chapter 11 “Technical specifications” on page 73 for the data sheet.
Please refer to pages 84ff. for the dimensional drawings.
3.2.2 The light curtain principle
The safety light curtain C4000 consists of a sender and a receiver (Fig. 1). Between these
two units is the protective field, defined as the protective field height and the protective
field width.
The construction height determines the height of the protective field of the appropriate
system. For the exact protective field height, please see Tab. 36ff. in chapter 11.5
“Dimensional drawings” on page 84.
The width of the protective field is derived from the dimension of the light path between
sender and receiver and must not exceed the maximum rated width of the protective field
(see “Technical specifications” on page 73).
Sender and receiver automatically synchronise themselves optically. An electrical connec-
tion between both components is not required.
The C4000 is modular in construction. All optical and electronic components and assemb-
lies are housed in a slim and torsionally rigid housing.
