Scanning light curtain MLVT

Several parallel light beams with a beam spacing of 7,5mm are controlled by a single-chip micro controller. One by one, all emitting diodes are checked. Therefore, a verification of the present status all diodes is realized. Via a serial interface, these data can be processed further.

Area of application

paint shops - controlling of spray guns
conveyor belts - assorting of cardboard boxes
wood industry - classification of trunks

Properties

parallel scanning - therefore no error of measurement
high speed scanning, reaction times only 1,2 ms to 10,3ms depending on construcional length
beam spacing only 7,5 mm (0,29 in.)
protective system IP 65
scasnning lentghs 100 mm up to 1900 mm in steps of 100 mm
operating range 7 m
small guards/valves directly connectable
2 short-circuit-safe non-equivalent semiconductor outputs, PNP, connecting capacity 0,5A/24V
serial interface (RS343c) for IPC or SPS (optional interface converter)

Serial RS 232C interface. Simple and easy-to-handle connection to SPS or to a PC.
On reception of a demanding signal issued by thecomputer or by the SPS, the receiver emits the number of the blanked emitting diodes ( or interrupted light beams) in binary code (polling). For special purposes, an interface converter for the conversion of RS 485 to RS 232C or Profibus-DP field bus is available.

Voltage:	24 V DC, +/- 20%, stabilized, max. 200mA
Connection:	integrated plug-in connector with PG9 als traction relief. alternative: marketable connectors.
Temperature of operational area:	-10 °C until 55 °C
Outputs:	PNP, outputs "FREE" and "INTERRUPTED, max. 500mA (short-circuit-safe), RS 485 interface(9600, N,8,1), optional converter to profibus-DP Fied bus/RS 232c
Protective System:	IP 65
Profibusadresse MLPB:	Standard 11 (optionally available with 1-125)

Aluminium-profile, anodized or plastic laminated RAL yellow 1020, end pieces consists of acid proof plastics (polyamide) reinforced by glass globes. Light emerging and reentry areas made of plexiglass, optional solvent-proof silikate glass windows.
