Giovenzana limit switches are the best that the could offer in terms of technology and performance. They satisfy the most various needs by covering application fields in the automation sector, lifts and general machinery.

NC Contacts with positive opening and different contact combinations, quick switch, slow or overlapping.

IP series foot switches are manufactured by Giovenzana, in order to complete the range of products with man-machine interface.

The range includes: foot switches with single, double execution and shaft compatible with emergency mushroom-shaped key EN ISO 13850; activations with electric contacts and pneumatic valves.

Activation with foot switch protection in thermoplastic material IP54 and not protected activation.

Giovenzana produces a wide range of pendant station fit for controlling overhead travelling cranes, cranes and lifting machines. The Family of pensile keyboards includes standard keyboards which are user-adjustable or simply combinable in order to offer a customized service on every kind of machine or customer.

Giovenzana’s range goes from keyboards with 2 to 12 keys in single line and 4 to 14 keys in two lines, where there are keys of many kinds and symbology, single or double speed, mechanically interlocked.

All Giovenzana’s pensile keyboards have protection grade IP65, which allows its use in locations with heavy humidity conditions, or where dust could compromise it. Studied and implemented through the years in order to reach high certifications, they are a benchmark for all operators worlwide, and they are used for moving materials both inside and outside industrial plants.

The Giovenzana’s rotary gear limit switch is a device used to control the number of rotation or direction angle of industrial and building machines. A typical application is to control the position of the rolling shutter door or overhead cranes etc… . The unit controls 2, 4 or more microswitches through a gear system and cams transmission, so that after a defined number of revolutions, it can prepare the motor or the device to start or stop running. The microswitches have a calibration screw that operates independently on each cam; so it can calibrate the opening and the closing of each micro according to the functional requirements needed. The gear-based transmission system allows you to choose different ratios.

The connection of the gear limit switch to the device to be checked is made through a metal shaft which can also be bulging on both sides of it.

Opportunity to be connected through flange, shaft-users interface through Oldham joint, which allows not aligned functioning, pinions for coupling with toothed wheels.

The position (rotary-angular) limit switch is used to control several handling system:

sophisticated crane system: the unit controls power operating system (ex. PLC) and allows the crane to slow-down and/or stop running.

hoist: the unit is used to stop the hoist running whenever it reaches a “limit” position.The heart of the hoist is made of a rotary commutator with 16 to 40 ends, with possible mechanical stop.

Different combinations available for all standard systems. – Customization available on request.

Anti-ageing PVC flat cables H07VVH6-F and round freestanding cables with lateral steel ropes S05VVD7-F.

Comply with the norm CEI 20-22 II (flameproof).

External cover in blue color.

Application field:

The employment field of flat and round cables is the lift one.

Flat cables are employed in festoon lines with serialized carts on ropes, bars and carts for IPE e IPN girders.

Round cables with side steel cores are employed in coordination with pensile keyboards for light liftings (block and tackle) or heavy liftings and movement (overhead travelling crane).
