• Insulation voltage 250V~
  
• Maximum operating voltage 250V~
  
• Black lower casing reinforced nylon
  
• Yellow cover high mechanical and thermal resistant thermoplastic
  
• Operating temperature - 20 °C + 60 °C
  
• Drive worm screw
  
• Cable entries PG 11

Standard executions are provided with 2 or even 4 contacts. Limit switches with 3 and 5 contacts can also be realized upon request and according to the necessary quantity.

FCN limit switches can be customized according to the order quantity. Specific customizations:

• shafts cut to measure
• cable entry in frontal or lateral position
  
• different contacts
  
• regulation cams with different profiles
  
• measuring accessories, such as potentiometers or encoders
  
• customized nameplates

The range of the accessories integrates and completes the limit switches series and facilitates their use according to particular requirements. A series of cog wheels, a male connection and a flexible shaft are the interfaces which have specifically been designed in order to transmit the motion easily from the motor shaft to the limit switch shaft. The fitting of a potentiometer, an encoder or another position sensor close to the micro switch group involves a linear exit in the same box.

A series of cog wheels of different diameters allows you an easy joining through pinions and belts.

• Module 5 with 12 teeth
• Module 6 with 11 teeth
  
• Module 8 with 12 teeth
  
• Module 10 with 12 teeth
  
• Module 14 with 10 teeth

The male connection helps the joining to motors or reducing gears.

The flexible shaft allows you to couple the shafts that are not perfectly aligned.

The flange interface allows the limit switch to be fixed without the special fixing plate.

The insertion of a potentiometer near the microswitch group involves a linear exit in the same box.

• Ensure that the locking screw is loosened.
• Set the desired resistance value by means of the instruments by rotating the regulating ring clockwise to reduce it, or anti-clockwise to increase it.
  
• Tighten the lock screw
  

IMPORTANT: The potentiometer follows the cams rotation direction.
