Limit Switch - 222:1 Series 55 Gear Ratio With 2 Contact Blocks Hubbell 55-4E-2SP-WR-222

Product Information

Specification

Also Known As :
 Hubbell is a well-known company that produces electrical and electronic products, including lighting, datacom, and power systems. In more complex automated systems, the dual contact blocks can serve to control various aspects of machinery based on the position or condition being monitored.

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 55 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.
• For every 222 units of movement or rotations at the input, there's 1 unit of movement or rotation at the output.
• This provides extremely fine precision and sensitivity. It allows for detection of very minute changes in position, especially relevant in applications demanding high accuracy.
• This type of gear ratio is commonly found in precision machinery or setups where small increments of movement are important.

Standards:
• Each contact block can have multiple configurations such as "normally open" (NO) or "normally closed" (NC).
• NO contacts will close, completing their circuit,NC contacts will open, breaking their circuit.
• With 2 contact blocks, the switch has the capability to simultaneously control or monitor two different circuits or actions.

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.
• Given the high gear ratio, this limit switch would be highly useful in scenarios requiring accurate positioning. Examples might include CNC machines, robotics, or specialized measurement equipment.

Features :

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.
