DESCRIPTION

The rotary limit switch is used to control the movement of industrial machinery. It operates as an auxiliary controller of electrical motors through a power interface, such as a contactor or PLC. Suitable for heavy duty, its shaft is connected to the motor and, after a set number of revolutions, the cams operate the switches, thus starting the predetermined movement. A worm gear and a helical toothed gear combined with one or more pairs of straight toothed gears are used for the transmission of the movement from the input shaft to the output shaft.

Revolution ratios, ranging from 1:1 to 1:969, result from the use of different combinations of gear wheels between the input shaft and the output shaft, which is connected to the cams operating the switches.
Transmission and gear driving shafts are made of stainless steel to prevent oxidation and wear. The gear wheels and the driving bushes are made of self-lubricating thermoplastic material, suitably chosen to reduce the wear to a minimum and to maintain the accuracy of the couplings over time. Sintered bronze bushes are moulded into the base of the limit switch to optimise the shaft rotation and to prevent rubbing with plastic material.

Each cam can be set with great accuracy thanks to the cam adjusting screws. The auxiliary switches are of a positive opening type, thus suitable for safety functions. It is available with direct control switches for operating directly on the motor.
The cam-switch sets can be substituted for potentiometers suitable for the connection to electronic equipment. Each output of the limit switch can be set with a different revolution ratio to allow for a diversified control of the machinery to meet special requirements.

Materials and components are wear resistant and protect the equipment against water and dust. The limit switch is available with a flange for direct coupling to the motor and it can be customised with labels and colours according to the customer’s requirements.

DESCRIPTION

The rotary limit switch is a device used for controlling the movement of industrial machines.
It is an auxiliary control and therefore commands the machine via a power interface, such as a contactor (or a PLC). Suitable for heavy use, it is connected by a shaft to a motor so that after a certain number of revolutions the cams operate the switches to start the pre-set movement. A worm gear and a helical toothed gear combined with one or more pairs of straight toothed gears are used to transmit movement from the input shaft to the output shaft.

Transmission ratios result from the use of different combinations of gear wheels between the input shaft and the output shaft, which is connected to the cams that operate the switches. The gear ratio ranges from 1:1 to (1:9400).

Transmission and gear drive shafts are in stainless steel to prevent oxidisation and wear. The gear wheels and driving bushes are in self-lubricating thermoplastic to reduce wear to a minimum and to maintain the accuracy of the couplings over time. Sintered bronze bushes are moulded into the base of the limit switch, to optimise shaft rotation and prevent it rubbing against plastic.

Each cam can be regulated with great accuracy using the cam adjusting screws. The auxiliary switches are positive-opening and can be used for safety purposes. There is also a direct-control version, which allows direct control of the motor.

All the materials and parts used are resistant to atmospheric agents and guarantee that the device is water- and dust-proof.

Available with cable entry clamp from below.

The base of the limit switch, in die-cast aluminium, has excellent resistance characteristics and ball bearings to optimise rotation of the shaft and prevent rubbing.
