Limit Switches

Product Details:

1. When it comes to restricting power supply Differential Limit Switch gives an optimum solution. It works on the principle of single lever grab control. They have six cam operations that work on their specific set limits. They are made for heavy duty application and are made out of cast iron exteriors. It protects the machine surface from pollutants like dirt and dust. Our products come with a comprehensive quality assurance.

Features:

• Heavy duty operation and power management
• Six cams for enhanced control
• Housed in IP-54 degree of protection

Other Details:

• APPLICATION : The grab different limit switch is driven by holding and closing winches is used in auxiliary circuits for single lever grab control.It is used for stopping the closing motor after closing or opening, regardless of the height of the grab, and starting the holding motor, after closing, for transition to the hoisting action, as well as for stopping the holding and closing motors at the highest and lowest grab positions.
• CONSTRUCTION : The switch contains six cam operated switch elements which are used as auxiliary circuit limit switches (see switching sequence diagram). The dimension drawing shows that the switch has two shafts which must be driven by the holding and closing winches.The contacts of limit switches are 40 amps rated at 500VA C.The limit switches are designed for heavy duty application housed in IP-54 degree of Protection. The housing is made of Cast Iron base & cover.The base and cover both have machined surface to protect against dirt and dust.

"OMEGA CONTROLS" Rotary Geared Limit Switches are used on control and power circuits of reversing drives so as to limit their rotation/movement within a predetermined position. The function of the Limit Switch is to stop the mechanism or drive at the extreme forward/reverse positions. The Limit Switches are particularly suited for use on reversing drives such as hoist, winches, rolling mills and various other mechanisms used in steel plants such as coke ovens, feeding machinery, valve drives etc. The contacts of Limit Switches are 40 amps rated continuously at 500 Volts A. C. The Limit switch can be provided with 2 NC contacts or 4 NC contacts or (2 NO + 2 NC) contacts as per the requirement. For Series Limit Switches are shields are provided. The frequency of switching of each contact is suitable for maximum 720 operations per hour. The speed of the driving shaft rotation should not be more than 60 RPM.

Features:

• High durable standards
• Optimum performance
• Easy to install

 

 

Heavy duty cranes and wagons can go for Lever Limit Switches. They can prevent the over travel of power with the contact points that are set for a fixed operation cycle. The limit switch cuts down the power supply automatically in case of oversupply. It reaches its predetermined position when the lever that is fixed on a girder is moved to projecting member. It is apt for 500 V. A. c and 50 cycles a second. The switch is prepared keeping in mind the international standards.

Features:

• Operation frequency permissible up to 720 operations per hour
• Four phase contacts that cuts off two phases of motor
• Automated power cutting procedure

When it comes to heavy power utilization then Crane Limit Switches provide reliability and perfect execution. The prevent traverse or over travel on control circuit and power lines up to 500 V.A. They can be used as shunt limit switch with the maximum operating frequency of 1000 cycles per hour. In series limit switch it works on 720 cycles per hour. Spring action ensures that the contacts are automatically reset to zero position. We test every part for high quality.

Features:

• High reliability factor for high power settings
• Comes with four sets of contacts
• Set maximum permissible frequency

A metal structure gives the necessary stability to Counter Weight Limit Switches that work on heavy cranes and wagons. They come with four contact points that cuts the motor two phases on each side. Each of these contacts has a permissible limit of 720 operating cycles per hour. They work on 500 V.A.C. of power and are apt for heavy operation. Our products comply with the highest industrial standards.

Features:

• Reliable and enhances safety
• Restricts over flow of power
• Automated closing system
