Limit and Enclosed Switches Global Limit Switches GLS Series Limit/Enclosed GENERAL INFORMATION The GLS series is specifically designed for world-wide applications and is supported by Honeywell global resources for sales and after sales service. Over 300 versions designed to the newest IEC standard are available and include a wide range of EN50041 and EN50047 type switches.
Limit and Enclosed Switches Standards/How to read and understand the bar chart information Standards IEC 947-1 explains the general rules relating to Low-voltage switchgear and controlgear. The purpose of this standard is to harmonize as much as possible the product performance and test requirements for equipment where the rated voltage does not exceed 1,000 VAC or 1,500 VDC. IEC 947-5-1 is part 5 of the general rules which relates to Controlcircuit devices and switching elements.
Limit and Enclosed Switches Degree of Protection NEMA Classification (USA) IP Classification The IEC 529 standard describes a system for classifying the degree of protection provided by the enclosures of electrical equipment. The level of protection given by the enclosure is indicated by the IP code. This code system uses the letters ‘‘IP’’ (International Protection) followed by up to four digits. Normally only the first two digits are used.

Limit and Enclosed Switches Proper Application of Limit Switches The following are guidelines for the correct application of Limit Switches. Never use the Limit Switch as a physical end stop. Mechanical damage or incorrect operation may occur if this is done. Always ensure that the mechanical actuator is protected from excessive mechanical shock. Never release the actuator suddenly – gradual actuation and release will ensure that stress on the mechanics of the switch is kept to a minimum.
Limit and Enclosed Switches Side Rotaries The side rotary assemblies incorporate a feature for adjusting the free position of the side rotary lever. The EN 50041 body style allows infinite adjustment and reclamp. The EN 50047 style allows clamping in 10° increments. See the following diagrams for details of the mechanism in each case.
Limit and Enclosed Switches Miniature EN 50047 body style Use same replacement procedure as above except that no retaining screw is involved. The basic switch is secured in the miniature housings by a press fit. To remove an inoperative switch, merely grasp the basic firmly and pull it out of the housing. Insert the new switch in its place. Then wire the new basic as before and test it in the application.
