Laser Safety Key Switch

Bulletin 42ef lasersight rightsight photoelectric laser sensors use eye safe class i visible laser light and feature the same mounting options as other products in the rightsight product line.

Laser safety key switch. All class iv lasers and laser systems require a master switch control. Hence the storage and protection of that eyewear is very important. Safety switches monitor doors gates and other movable physical guards that separate personnel from a hazard. Laser eyewear can be stored inside or outside of the laser use area or at both locations.

Three safety interlock outputs. An interlock is a circuit that remains broken if a safety condition is not met. Lasermet s interlock controllers provide control of an interlock system primarily intended to protect personnel from accidental exposure to hazardous lasers. A key lock prevents unauthorised use of the system.

Interlock systems laser interlock systems the ics 6. Through 21 cfr 1040 the us food and drug administration fda regulates laser products entering commerce and requires all class iiib and class iv lasers offered in commerce in the us to have five standard safety features. The ics 6 has a fully dual channel cross checked architecture and when correctly wired can realise a system compliant with en iso 13849 1 up to performance level e. They send a signal to the machine control system if the guard has been opened removed or out of position.

They are able to monitor several doors windows curtains or roller blinds fitted with safety interlock switches and disable the laser if any are open. If light manually controlled light switch shall be located in a convenient position near the laser control eyewear storage a critical element of laser safety is laser protective eyewear. A key switch a safety interlock dongle a power indicator an aperture shutter and an emission delay normally two to. When disabled key or code removed the laser cannot be operated.

The law requires a key switch and a safety interlock to come with all class 4 lasers. An arm laser button is provided to arm the laser when all the safety requirements are met. This safety unit can be connected to the rs 232 interlock interface of a laser projector. The switch can be operated by a key or computer code.

Only authorized system operators are to be permitted access to the key or code. For example an interlock might prevent shut down the laser if the room s door or the casing are open instead of safely closed. Class i lasers require no additional safety or protective training or equipment and are safe for general purpose use.
