ROUND UP

Safety light curtains optimised for vibration Leuze MLC 500-V Series safety light curtains have been optimised specifically for applica- tions subject to strong vibrations, such as for safe-guarding presses, punching machines and similar large equipment. These reliable safety light curtains have unusually slim dimensions of only 29 mm by 35 mm, but clever engineering has ensured slightly set back front screens, reinforced side walls and metal end caps, all of which result in a sturdy construction. In addition, the new vibration-resistant Leuze MLC 500-V models were designed to provide extra protection for the high quality electronics. The safety light curtains are mounted on specially developed BT-2SB10-S swivel mount brackets that are largely able to compensate for excess vibration. This is an important feature with long light curtains, typically longer than 900mm. Shorter light curtains can be simply and conveniently mounted on machinery such as presses using adjustable vibration-damped BT-2R1-S swivel brackets. Form fitting mounting is possible due to removable swivel mount cylinders and this means that there is no dead space into which unpermitted access would be possible. With the extended functionality of these V-models, the user has access to functions that can be adjusted without a PC. These include three scan modes and fixed and floating blanking. This simplifies and speeds up the in-feed of the work pieces and contributes to more efficient production, since there is no interruption to the manufacturing process.

Connecting industrial safety controllers Molex , LLC has introduced Brad HarshIO Ethernet modules to provide a reliable solu- tion for connecting industrial safety controllers to sensors and actuators in harsh duty environments. Machine mountable in an IP67 rated housing, Brad HarshIOmodules are ideally suited for industrial applications where liquids, dust or vibrationmay be present, and have been tested to withstand shock, high-vibration and high temperatures.The Brad HarshIO modules are designed for safety applications, up SIL3 (Safety Integrity Level 3), Cat4/Ple, where communication over EtherNet/IP is needed to exchange safety and standard control data and diagnostics information over a single Ethernet network. The compact modules offer 12 safe inputs and four safe outputs, supporting connection of single and dual channel safety devices - ideal for automotive ap- plications running robots in cells.The digital inputs and outputs can connect to both standard and safety rated sensors and utilises test pulses for connected standard outputs to perform diagnostics on panel lamps, buzzers and standard actuators. An overmoulded on-board memory key, available

internally or M8, stores the configuration allowing module replace- ment in a minute without any special tools or re-commissioning. Enquiries:Yoshiko Helena Eping. Email yoshiko.eping@molex.com
