MULTIPLE LIGHT BEAM SAFETY DEVICES

MLD 500

Easy setting up of an access guarding with integrated Laser Alignment Aid

MLD 500 Multiple Light Beam Safety Device with integrated Muting indicator in an application with Sequential Muting

Typical areas of application

Access guardings with and without Muting on robot cells, processing centers, production lines

Packaging machinery, palletizers, wrapping machinery, plastic and rubber machinery, concrete and stoneware machinery, etc.

Rear zone guarding on pressure forming presses

It is advantageous from a cost effective-ness and optimum usability standpoint touse safety sensors that are characterizedby functions that match the specificrequirements of the given application asclosely as possible. The Multiple LightBeam Safety Device MLD 500 (type 4,PLe) has been specially designed for this.

As for the MLD 300 series (type 2, PL d),the MLD 500 sensors are characterized bytheir individual function classes. A start/restart interlock and contactor monitoringcan thereby be selected and, if necessary,various Muting modes realized. The seriescan be used both as standard accessguarding as well as for applications whereSequential, Parallel or Partial Muting isrequired. Additional Muting devices are notrequired, thus simplifying construction andlowering costs during setup of the Mutingapplication.

The series is predestined for wide-areaperimeter guarding, which is realized withDeflecting Mirrors, enabling operation atranges of up to 70 m. In addition to trans-mitter/receiver versions, 2- and 3-beam(patented) Transceiver versions are alsoavailable. No PC is necessary for configu-ration, as the functions are set via the pinassignments at the connection. Operatingtemperatures as low as -30°C are possi-ble. Options such as the Laser AlignmentAid, a Muting indicator and the patentedswivel mount for easy fastening and align-ment round out the MLD product range.

MLD 300

Access guarding with 3-beam Transceiver of the MLD 300 series for conveyor and storage systems

MLD 300 Multiple Light Beam Safety Device with integrated parallel Muting at one conveyor line

Typical areas of application

Print and paper machinery; Packaging machinery in accordance with EN 415

Conveyor systems in accordance with prEN 620; continuous conveyors for piece goods in accordance with EN 619

Woodworking machinery in accordance with EN 691, textile machinery, e.g. in accordance with ISO 11111

Protective devices for storage and narrow passages in accordance with DIN 15185, Part 2

Further areas of application: machinery and plant systems acc. to C-standards, in which category 2 safety devices are required

It is advantageous from a cost effective-ness and optimum usability standpoint touse safety sensors that are characterizedby functions that match the specificrequirements of the given application asclosely as possible. The Multiple LightBeam Safety Device MLD 300 (type 2,PLd) has been specially designed for this.

As for the MLD 500 series (type 4, PL e),the MLD 300 sensors are characterized bytheir individual function classes. A start/restart interlock and contactor monitoringcan thereby be selected and, if necessary,various Muting modes realized. The seriescan be used both as standard accessguarding as well as for applications whereSequential, Parallel or Partial Muting isrequired. Additional Muting devices are notrequired, thus simplifying construction andlowering costs during setup of the Mutingapplication.

The series is predestined for wide-areaperimeter guarding, which is realized withDeflecting Mirrors, enabling operation atranges of up to 70 m. In addition to trans-mitter/receiver versions, 2- and 3-beam(patented) Transceiver versions are alsoavailable. No PC is necessary for configu-ration, as the functions are set via the pinassignments at the connection. Operatingtemperatures as low as -30°C are possi-ble. Options such as the Laser AlignmentAid, a Muting indicator and the patentedswivel mount for easy fastening and align-ment round out the MLD product range.
