DESCRIPTION

7551 position limit switches are designed for the control of complex operating equipment. As they are control auxiliaries, they act on a power interface.

The choice of materials, technical solutions and ample size make these limit switches ideal for use in strongly aggressive environments where they are exposed to the most severe operating conditions, guaranteeing impeccable function at all times and for their entire life.

The enclosure is made of die-cast aluminum alloy and is resistant to any violent impact, chemical aggression and rust, while the bushings in sinterized material eliminate the need for any operations of routine maintenance of the header, since they are also made of impact-resistant zama.

7551 limit switches are equipped with 4 fastening holes and 3 outputs for wire clamps to reduce installation time and facilitate wiring operations.

DESCRIPTION

Tango is a position limit switch designed to control overhead travelling cranes, hoists and machine tools. It operates as auxiliary controller of electrical motors through power interfaces, such as contactors or PLCs.

Tango is the latest generation of position limit switches: the peculiar design and the use of high performing polymers ensure high resistance and endurance under the heaviest utilisation conditions.
Its design and overall dimensions facilitate installation and maintenance operations.

Both the enclosure and the head of Tango are made of thermoplastic material (nylon reinforced with fibreglass) ensuring wear resistance and protecting the equipment against water and dust. X-type rods can move to 4 maintained positions.
Inner components are made of tecno-polymers guaranteeing a long life-cycle and constant performance even at extreme temperatures.

Tango is equipped with 1NC slow action switches or, upon request, 1NO switches.
All switches are of the positive opening type, thus suitable for safety functions

DESCRIPTION

Position limit switches are designed to control the movement of overhead travelling cranes, hoists and machine tools. They operate as auxiliary controllers of electrical motors through power interfaces, such as contactors or PLCs.

Both the enclosure and the head of the limit switches are made of thermoplastic material (nylon reinforced with fibre glass). Materials and components ensure high resistance and endurance and protect the equipment against water and dust.

The X-FCS series has “T” or “Cross” rods which may move to 3 or 4 maintained positions, while the X-FRZ series features a single rod or a rod with roller with spring return movements.

The limit switches are equipped with 1NO+1NC snap action switches or, upon request, with 1NC slow action switches. All switches are of the positive opening type, thus suitable for safety functions.
