Preventing acccidents with conveyor systems
In assembly logistics, modern conveyor systems are used especially for flexible assembly concepts, such as component assembly in electromobility. Such conveyor systems must be safeguarded against collisions in order to protect people. The safeguarding of such applications is a particular challenge because these machines have a high moment of inertia and long stopping times.
To safeguard such applications, we have been developing and supplying high-quality and reliable HSB safety bumper , also known as switching buffers, for over three decades. These are contact-sensitive sensors that detect contact with a person or part of a person's body. If a bumper detects contact or an obstacle, the automatic drive of the machine is switched off immediately.
Development of an individual safety bumper - a case study
With our standardised cross-sections and materials, we secure a large number of applications in practice. For particularly challenging applications, we develop customised security solutions that are completely tailored to the individual requirements and wishes of our customers with regard to dimensions, shapes, colouring and the materials used.
This was also the case when securing the LOGO!MAT eCart of our long-standing customer KRUPS Automation GmbH. You can see in this video how the development, production, delivery and installation of our HSB safety bumper on the LOGO!MAT eCart works.
Many thanks for the close and successful cooperation!

- Highest safety standards: our bumpers meet category 3 and performance level d requirements in accordance with DIN ISO EN 13849-1.
- Optimal switching performance: minimal force required to trigger the switch and short feedback signal paths Depending on the application, various contact chains are used to achieve an optimal switching behaviour.
- Customisation: a wide range of dimensions, shapes and colours are available depending on your specific application.
- Cost reduction: you do not need to purchase a special control unit as the Haake contact chain features normally closed contacts allowing the signal to be processed directly. Besides a simple financial advantage, it also eliminates the need for complex connection and wiring work.
- Conformity: all our bumpers are manufactured in accordance with the Harmonised Standards and therefore meet all requirements of The Machinery Directive 2006/42/EC.
- Plug and play based on customer specifications: safety edge is connected directly to the available emergency stop module of your conveyor systems.

FAQ: Frequently Asked Questions about the Safety of Shear and Pinch Points
Modern conveyor systems often have high inertia and long stopping distances. Without additional safety measures, collisions can lead to serious injuries. Reliable safeguarding is therefore essential.
HSB bumpers are touch-sensitive sensors. As soon as they detect contact with a person or an obstacle, they send a signal to the control system and the drive stops immediately.
They are used, for example, in e-mobility, in flexible assembly concepts or component assembly. A practical example is the safeguarding of the LOGO!MAT eCart from KRUPS Automation GmbH with customized HSB bumpers.
Yes, the systems are modular and can be integrated into existing conveyor systems without major modifications.
