Product Information
Specification
Also Known As :A limit switch is a type of electromechanical device that operates when its actuator reaches a preset position, thereby either opening or closing an electrical connection. It's used in various applications to detect the presence or position of an object.
About :
Limit the travel of electrically operated doors, conveyors, hoists, machine tool work tables and similar devices. Equipment having rotating mechanisms, or linear motion which can be translated into rotational motion, can be controlled by these versatile switches. Furnas Series 54 switches can be mounted in any position and are easy to wire and adjust.
Common Applications: :
• Used in electrical circuits to control the operation of machinery.
• If we're discussing limit switches, a high gear ratio might be used to detect very specific positions or conditions, and the multiple contact blocks could be used to control various functions of the machinery based on those conditions.
• This is a mechanical specification indicating the relationship between an input and an output in a gear system. For every 72 rotations of the input gear (often the pinion), the output gear (or driven gear) will complete one rotation. Such a high gear ratio indicates:
Standards:
• The multiple contact blocks are useful in complex machinery or systems where multiple actions or feedback mechanisms are required when a particular position or condition is reached.
• Machines that require very accurate positioning or movement might employ such a limit switch. The high gear ratio ensures precise activation, while multiple
• This references an electrical component of a device, possibly a switch or relay. Each contact block typically consists of one or more electrical contacts that can be "normally open" (NO) or "normally closed" (NC). When the device is actuated:
• NO contacts will close, completing their circuit.
• NC contacts will open, breaking their circuit.
Construction :
• Consists of springs, levers, and other components that transfer the motion of the actuator to the contacts.
• Made of materials that offer durability and reliability over many operating cycles
• Options to mount the limit switch in place, which could include flanges, brackets, or holes for screws/bolts.
• Such a gear setup might be used where you need to detect a position or event very precisely. The high gear ratio allows for fine-tuning of the exact point of activation.

Industrial Machinery:
• To detect the presence or position of objects or parts.
Safety Interlocks:
• To ensure that dangerous machinery is powered down when access doors are opened.
Position Detection:
• In elevators, doors, gates, etc., to detect the open or closed position.
Installation:
• The switches should be installed according to the manufacturer's specifications and guidelines, considering the environmental and operational conditions.
Maintenance:
• Regular maintenance checks to ensure that the switch is operating effectively and safely. It may include cleaning, inspection, and testing.
Voltage and Current:
• Indicates the maximum voltage and current that the switch is rated for. Exceeding these ratings can cause failure or unsafe conditions.
Slow Speed:
• The output shaft turns at a much slower speed compared to the input shaft.
Increased Torque:
• There is an increase in torque at the output, making it suitable for applications requiring substantial force.
