Worm gear limit switch STROMAG

Worm gear cam limit switches
Series HGE

Standard switches
HGE series geared limit switches are universal mechanical switching devices for industrial applications.
They consist of a reduction gear and one or two contact spaces containing the switching contacts and the co-ordinated cam discs.
By the reduction gear a number of revolutions, which are transmitted to the input shaft of the geared limit switch, are reduced to an angle of rotation at the cam disc of max. 320° (with 40° cam discs).
Then the adjustable cam discs actuate the mechanical switching contacts.
By utilisation of mechanical switching contacts with forced separation to VDE 0660 part 200, limit switches are preferably used in the hoisting technology.
For that purpose the entire mechanical construction from the input shaft up to the contact bridge is positively driven. The only exception are the cam discs "V", which are fitted when particularly required by the customer, and the block adjustment.

Construction
* In relation to the reduction, the gearbox is designed either as worm gear or worm spur gear.
* All gear parts are made of metal and are lifetime-lubricated with high-quality gear lubrication Spectron F00.
* All housing parts consist of seawater-proof aluminium.
* The input shaft is made of stainless steel.
* Input shaft and switching shaft are ball bearinged.
* In relation to the number of contacts, the contacts are located in one or two switching spaces.
* With one switching space only, right-side or left-side arrangement to the input shaft can be selected optionally.
