Feelerleisten

Feelerleisten, also known as feeler strips or sensing strips, are a type of safety device used in automated machinery and industrial equipment. Their primary function is to detect contact and trigger an immediate stop or reversal of a machine's movement, thereby preventing injury to personnel or damage to equipment. These strips are typically made of flexible rubber or plastic and contain electrical conductors embedded within them. When the feeler strip is compressed or deformed by an impact, it closes an electrical circuit, signaling the control system to halt the machine.

The application of feelerleisten is widespread across various industries, including manufacturing, robotics, and material handling. They are commonly found on the edges of automated doors, moving platforms, robotic arms, and other machinery where there is a risk of collision. The sensitivity of a feelerleisten can often be adjusted to suit the specific application and the types of objects or people it needs to detect. Installation typically involves mounting the strip along the vulnerable edge of the equipment, with the electrical connection routed to the machine's safety control unit.

The effectiveness of feelerleisten relies on their ability to provide a rapid response to physical contact. They are a crucial component in a layered approach to machine safety, working in conjunction with other safety measures such as light curtains and safety mats. Regular inspection and maintenance are important to ensure the reliable operation of feelerleisten and to maintain a safe working environment.
