New safety distance sensor for safe cliff detection and access protection

The WTT12-S is a safety distance sensor with time-of-flight technology (TOF) for safe object detection in process automation. It achieves SIL1 / PL c and ensures safe and reliable object detection with a switching distance of 50 - 2000 mm.

Safety sensor for muting and fall edge detection up to SIL 1 and PL c

WTT12-S is suitable for challenging applications in logistics, intralogistics and packaging industries thanks to VISTAL® housing and IP67 protection class and its compact housing for easy integration.

Exceptional characteristics include dependable object detection, capable even under challenging environmental circumstances such as short distances, rapid object sequences, and resistance to ambient light interference. Moreover, the WTT12-S presents a straightforward, highly resilient, and cost-effective solution for certified machine safety, boasting swift connectivity and uncomplicated parameterisation.

The right fit for your application

Whether as a muting sensor in intralogistics processes or as a solution for the secondary protection of mobile robots — WTT12-S sensors are versatile and space saving. The sensors reliably detect objects and drop-off edges in the room and transmit this information to the safety controller. WTT12-S sensors provide flexible mounting options and are easy to parameterize. They are easy to connect thanks to the standard M12 male connector.

With their compact design, the WTT12-S sensors can be integrated into almost every machine design in a space-saving manner. Thanks to their rugged VISTAL housing, they resist even the most challenging ambient conditions.

Benefits include:

  • Ensuring safety for both individuals and assets through dependable object detection.
  • Streamlining the certification process for machines without requiring any workarounds.
  • Detecting moving objects and drop edges even across extended distances.
  • Excelling in challenging ambient conditions due to its durable housing and immunity to ambient light.
  • Simplifying sensor parameterisation through a teach-in button and seamless connection to the safety controller via M12 plug connectors.
