Protective devices particularly include electrosensitive protective equipment (ESPE). This term covers the following technologies: optical sensors such as single-beam light barriers and safety light curtains, safety laser scanners and camera-based protection systems. In addition to classic ESPE, secure radar systems also fall under the category of electrosensitive safety solutions.
There are some things that all the technologies have in common: highest safety level, short response times, diagnostic interfaces for troubleshooting, easy configuration and operation, plus robust product features for higher availability. The technologies thus combine safety and productivity with user-friendliness.
