Designed to EN50041 characteristics and mounting The GSS family of limit switches are specifically designed for use in safety applications. All the units have been independently tested to IEC947-5-1/EN60947-5-1 standards and comply with the essential requirements laid down (Low Voltage Directive for Switchgear) They are all marked positive break and comply with the requirements of the Machine Directive (89/392/EEC) as amended by Directive 91/368/EEC These are Category 1 devices per EN954-1 (the machine directive) Category can be raised to 4 by using in association with safety relays IP67 Rating
Typical applications: On guard doors where key alignment has proved to be a real problem and cannot be solved by key operated switches. The user needs to differentiate mission critical safety components on the machine from regular sensors
Use this limit switch from Honeywell on your machinery's gates and guards. It has a bright red body colour, so it's instantly recognisable as a safety device. For versatility, it provides up to four electrically independent contacts, so you can configure it to work with your specialised equipment. The rugged metal housing is epoxy-coated to prevent corrosion, making it suitable for use in harsh conditions. An IP67 (ingress protection) rating means it's dust-tight and can withstand temporary submersion in water, so it can stand up to the demands of heavy industry.

Agricultural industry Construction machinery and equipment Gates, guards and doors Scissor and platform lifts
When should I choose a limit switch with a roller plunger actuator?
You should choose a roller plunger when a plunger-type actuator is needed but a force or moving object won't hit it directly at a 90º angle. Roller plungers use non-perpendicular force to create the perpendicular force needed to activate the switch.
