English term or phrase: increased contact ratings
applications for laser sensors

"Robotic Welder Guarding

The XXX controller can stop hazardous motion either by detecting a presence in the horizontal sensing field, or by an individual activating the integral E-stop input. The safety outputs of the light curtain can be interfaced with an Emergency Stop Monitoring Safety Relay to provide a latch/reset function. By incorporating the Emergency Stop Monitoring Safety Relay, the system also allows for ***increased contact ratings***, additional safety output contacts and PLC feedback outputs."

See explanation below...

Your system produces a direct output (quite likely a dry contact), but this may not have the capacity to switch heavy loads (like a motor, for example) --- by capacity, we mean the ability of the contacts to carry the current involved --- in practice, it is often the ability to INTERRUPT the current that is the problem, since small contacts may arc and weld together if opened when carrying too much current.

Here, they offer the add-on 'Emergency Stop Monitoring Safety Relay', which will presumably be more substantial, i.e. will have contacts with a higher rating (capable of switching a heavier load...)

In other words, the small direct output of the main device is used to operate this 'ESMSR', which is more heavily rated so as to handle bigger loads (as well as offering the additional benefits mentioned...).
