The many new performance features, long ranges, and the differing beam separations and numbers of beams available, all make the M 4000 Standard multiple light-beam safety device a worthy successor to the trend-setting MSL.

Comfort and flexibility already come to the fore during the initial installation. Configuration buttons on the device, the optional integrated laser alignment aid for every single beam of the M 4000 Standard, optical synchronisation between the transmitter and the receiver, and the seven-segment indicator rapidly get access protection ready for operation. 

Those who want to know the current device status in detail at a glance and from a distance can, if desired, obtain the required information from the LEDs available on the receiver housing.

Parallel to this, the configurable status output offers the opportunity to transfer M 4000 Standard operating information directly to the machine’s control system for diagnostic purposes. The separate connection for the reset button on the M 4000 Standard is a further user highlight. As signal evaluation takes place in the device itself there is no longer any need to trace back the signals from the control cabinet to the hazardous area, as required by other systems – considerably reducing cable complexity.

Connections and uses

The new M 4000 Standard is suitable for all control environments from relays and the safe PLC right up to the safe fieldbus. Combination with SICK UE 10 and UE 100 series interface modules is possible, as is connection to safe fieldbuses via the safety bus nodes of the UE 1000 series, and networking with AS-Interface Safety at Work.

The new multiple light-beam safety device is not only big in comfort and interface variety, but also regarding its potential areas of use. Ranges of 0.5 to 20 metres or 15 to 70 metres can be configured. Then there are the differing beam numbers, available with separations of 300, 400, 450, 500 and 600mm in accordance with the latest international standards.

The M 4000 Standard thus covers numerous practical access protection requirements on machines and plant.
