The SRO rope pull switch from Bernstein is versatile due to its modular design. With the help of the compact cable pull switch, a large area can be secured with just one switch and one cable. Before the user holds his SRO in his hands, he can select the housing and actuator from metal or plastic and combine them. In addition, he can choose between 2 and 4 contacts. On request, Bernstein can also equip the switch with an emergency stop button in addition to the rope. Areas up to 30 m in length can be secured with the SRO.

Guard locking: Safe, versatile, powerful

The Schmersal Group is launching a new electromechanical safety locking device on the market: The AZM150 is characterized by a slim design and a locking force of 1400 N. The device can be combined with three different actuators for different mounting situations, a straight actuator for sliding doors, an angled one Actuator for large swing doors and a movable actuator for smaller swing doors. A plus point of the tumbler is the rotatable actuator head, which - instead of being screwed on - can be locked by simply putting the cover on. This enables various mounting positions and approach options.

Seminar tip

The ISO 13849 standard describes new methods for evaluating safety functions. The seminar "Use of the DIN EN ISO 13849 safety standard when setting up machine controls" shows how this standard must be observed.

Light curtain: Muting function integrated

The new XUSL4M safety light curtains (type 4) from Telemecanique Sensors offer machine operators a high level of protection thanks to the muting function. In the field of packaging and palletizing or in roll handling systems, robot production cells, transfer lines and assembly lines, the optical protective device shows its strength because it differentiates between people and material. The XUSL4M are available in basic and advanced versions and can be equipped with various muting arm options for specific applications. They have integrated functions such as automatic or manual start / restart interlock.

Tilt sensor: operate directly on the PLC

The Profisafe inclination sensor NBT / S3 has been certified by TÜV according to the standards EN61508 and ISO13849. Thanks to its redundant sensors and internal monitoring measures, it achieves SIL2 or PLd classification. This means that it can be operated directly on a safe controller. It provides a safe angle of inclination with a resolution of 0.01 degrees. The version with a measuring axis has a measuring range of ± 90 degrees and is suitable for all tilting or rotating movements around an axis, the 2-axis version with a measuring range of ± 20 degrees for both axes, however, for leveling platforms and vehicles.

Machine safety user meeting

Machine safety is an important issue: the correct standards must be taken into account and the requirements of the Machinery Directive must be complied with. The machine safety user meeting supports developers and designers to ensure the functional safety of machines and systems.
