Light barriers, light curtains and light grids are all classed as electrosensitive protective equipment (ESPE). They are optoelectronic protective devices and are an effective, cost-saving alternative to conventional mechanical guards.

PSENopt devices are used to safeguard access to danger zones, where the production process requires active intervention. An invisible protected field of infrared beams monitors the interaction between man and machine. If a light beam is broken it will immediately trigger a safe shutdown command. In this way you can protect your staff from injury, safely and effectively - without causing an obstruction.
