Light barriers ELS 30 series
Light barriers of the ELS 30 series are through-beam light barriers, they consist of a separate transmitter and a receiver unit.
They work with a robust unfocused light ray and achieve long ranges due to their high light output.
Technical specifications | ELS series (depending on type) |
---|---|
Extraneous light tolerance | insensitive to extraneous light (only ELS 30-7) |
Function | transmitter/ receiver |
Switching frequency | 100 Hz / 1 kHz |
Output | pnp+npn (opt. plus function reserve) / analogue (3-8 V) |
Connection | cable/ plug |
Measuring range | max. 30 m /100 m (with lens optics) |

Advantages:
- high range: up to 30 m
- high tolerance against pollutiondue to unfocused light and high light energy
- alignment of the light barriers does not require any optical aids, a safe function is guaranteed even with a displacement of several degrees
- ELS 30 ..7 A S/E light barriers are unaffected by extraneous light and are supplied with a connecting cable between transmitter and receiver
Application examples:
- downpipe monitoring
- garbage container cleaning
- aluminium rolling mill
