Heavy-duty lever limit switch designed for EOT cranes and wagon shunting devices to prevent over-travel. Operates up to 500V AC, 50Hz, with 10A or 40A current rating and IP54 aluminum casting enclosure.

The Lever Limit Switch is designed for heavy-duty industrial applications such as EOT cranes and wagon shunting systems. It prevents over-travel or over-traverse by interrupting the power and control circuits when the lever reaches its pre-set position. The lever actuates upon contact with a projecting member fixed to the girder and automatically resets to its original position through spring action. The switch is built with a durable aluminum cast body, offers IP54 protection, and supports operating voltages up to 500V AC at 50Hz. It is available with 2, 3, or 4 contacts and rated for 10A to 40A current, ensuring dependable performance in demanding crane and hoist operations.

Heavy-duty gravity-operated limit switch designed to control motion limits in EOT cranes and hoists. Ensures safe and reliable operation by stopping motion at predetermined positions.

The CMK Gravity / Counter Weight Limit Switch is designed for precise motion control in EOT cranes, hoists, and other lifting machinery. Operated by a counterweight mechanism, this switch automatically limits rotational or travel movement within a pre-set range, ensuring operational safety and preventing mechanical over-travel. Built with a durable M.S. sheet body and enclosed in an IP-55 rated housing, it withstands harsh industrial environments. The switch offers multiple contact configurations with silver cadmium double-break contacts for superior conductivity and long service life. Ideal for heavy-duty applications in material handling and lifting systems, it ensures reliable performance and minimal maintenance requirements.

Heavy-duty rotary gear limit switch designed for reversing drives like hoists, cranes, and winches. Ensures accurate motion control and safe operation with adjustable cams and durable thermoplastic housing.

The Rotary Gear Limit Switch consists of a heavy-duty worm gear drive enclosed in a cast housing. The cam shaft extending from the gear accommodates adjustable cams fitted with actuators that strike the contact fingers of the respective contacts.
This mechanism accurately stops the drive at the desired limit positions in both clockwise and anti-clockwise directions. It is ideally suited for reversing drives such as electric hoists, winches, overhead cranes, and traverse mechanisms.
Built with impact-proof thermoplastic housing and IP-65 protection, it ensures durability and performance even in harsh industrial environments.

Key Attributes
  • Drive Type Worm Gear Drive
  • Gear Ratio 1:12, 1:25, 1:50, 1:100, 1:200, 1:400
  • Cover Material Impact-proof Thermoplastic
  • Degree of Protection IP-65
  • Contact Material Double Break Silver Cadmium
  • Rated Voltage 500V AC
  • Max Rotation Speed 1200 rpm
  • Mounting Suitable for direct coupling with drive shaft
  • Application Area Hoists, Winches, Cranes, Rolling Mills, Steel Plants
