It is advantageous from a cost effectiveness and optimum usability standpoint to use safety sensors that are characterized by functions that match the specific requirements of the given application as closely as possible. Leuze electronic developed the new MLD 300 (type 2, PLd) and MLD 500 (type 4, PLe) series Multiple Light Beam Safety Devices especially with this in mind.

The individual models of the respective series are equipped with certain features and capabilities (function classes). By selecting a given function class, the user can appropriately determine the performance of his safety sensor for the application and the respective requirements. For example, the start/restart interlock and contactor monitoring functions are available and, if necessary, various Muting modes can be selected. As a result,the series can be used both as standard access guarding as well as for applications where sequential, parallel or partial Muting is required. Additional Muting devices are not required, thus simplifying construction and lowering costs during setup of the Muting application.

Higher MLD function classes, such as MLD 330 or MLD 530, feature an integrated Muting indicator and a 7-segment display, which the user can use to immediately determine the cause of sensor behavior and initiate the proper countermeasures.

The series is predestined for wide-area perimeter guarding, which is realized with Deflecting Mirrors. Ranges of up to 70 m and operating temperatures up to -25 °C are here possible. With the integrated Laser Alignment Aid, alignment of such safeguards is noticeably simplified. A reflective element integrated in the cap on the receiver side of the system ensures clear visibility of the alignment laser spot, even over long distances. The Deflecting Mirror columns necessary for perimeter guarding can be simply and quickly aligned, step-by-step. The setup time is considerably reduced.

In addition, with the new BT-240 swivel mount, the safety sensor can be flexibly turned 240° on its own axis, easily aligned and reliably mounted—an extremely practical solution for further simplifying and accelerating use of the devices.
