Flameproof (FLP/WP )   LEVER LIMIT SWITCH

Suni  Make FLP/WP  Lever Limit Switch is used for heavy duty E.O.T. Cranes, Wagon shunting devices etc., to prevent over travelling or over traversing on power and control circuit up to 500 volts A.C. 50 cycles / second and 40 amps current rating. We are counted among the ecstatic Lever Operated Limit Switch Manufacturers in India.
 Suni  makes FLP/WP Lever type Limit Switch normally remains closed and cuts off power to stop the motor of the particulars motion. Suni Make FLP/WP Lever Limit switch is Flameproof Testing as per IS/IEC 60079-1:2007 & Dust Ignition protection as per IS/IEC 60079-31:2008 & Weatherproof Testing as per IS/IEC 60529:2001 for IP 66 Enclosue in die cast Aluminium alloy LM6 for used in Zone 21, 22 and 1 & 2 for Gas Group: IIA ,IIB & IIC Atmospheres,Suni Make FLP/WP lever Limit switch operates when its lever reaches its pre-determined positionand the lever is moved over a projecting member fixed on the Girder.The Limit Switch contacts are automatically reset when the lever returns to zero position due to spring action.
The FLP/WP Lever Limit Switch is made  in IP-66 enclosure. in case of IP-66, the cover is of Cast Aluminum. Also in this case the base and cover have machined surface to protect the Limit Switch against dust.The cam shaft on which the cams are fitted is mounted in the housing on moulded bushes of synthetic material which are fixed to the front and rear walls by means of screws.The Cams which are fitted on the cam shaft are moulded from the highest quality synthetic material and are accurately cut to correspond to the switching sequence desired.The contacts have a maximum continuous Current capacity of 40 amps AC.The contact tips are made of high grade Silver Cadmium Oxide alloy.When used for Series operation [up to 40 Amps maximum], the Contacts are suitable for 720 operations per hour and in case of Shunt operation [for Control Circuit], the Contacts are suitable for 1000 operation per hour.
The same Contacts can be used in Series as well as in Shunt configurations,The switching capacity of the Contacts when used for Shunt operation is 15 amps at 400 Volts, AC on highly inductive load and 2.5 amps at 220 Volts DC.
These switching capacities in fact are far in excess of what is actually required in practice and hence replacement of Contacts for Shunt may not be necessary for a long time.The body of the Contacts is made of high grade Melamine which is specifically suited for heavy duty operation .The material is non – tracking and is capable of with standing heavy arcing.

                                       Flameproof (FLP/WP ) ROTARY GEAR LIMIT SWITCH
Suni  makes Flameproof (FLP/WP )Rotary Gear type Limit Switch that is used on Control / Power circuit of reversing drives so as to limit their rotation / movement within a predetermined position.The Flameproof (FLP/WP) Rotary Limit switch FlameproofTesting as per IS/IEC 60079-1:2007 & Dust ignition protection as per Is/IEC 60079-31:2008 & Weatherproof Testing as per IS/IEC 60529:2001 for IP 66 Enclosue Material is in Die Cast Aluminium Ally LM6 & used in Zone 21, 22 & 1&2, for gas Group-IIA,IIB & IIC atmosphere
The function of the Limit Switch is to stop the mechanism of drive at the extreme clock wise / anti clock wise position. Suni Make Rotary Limit Switches are particularly suited for use on reversing drives such as Electric Hoists, Winches, Over Head Cranes, Traversers etc. The contacts of these Limit Switches are rated for 40 amps at 500 Volts A.C.The Limit Switch can be provided with 2NC contacts or (2No + 2NC) contacts as per the requirement.The geared type rotary limit switch basically consists of heavy duty worm gear drive with a ratio of 48:1 The Crane Duty Rotary Geared Limit Switch is made in IP-66 enclosure.
 in case of IP-66, the cover is of cast Aluminum. Also the Base and cover have machined surface to protect the Limit Switch against  dust.The cam shaft which extends from behind the gear into the Aluminium housing accommodates the cams.
2 or 4 cams are used depending upon whether the Rotary Limit Switch is of 2 contacts or 4 contacts operation.The contacts have a maximum continuous Current capacity of 40 amps AC.The contact tips are made of high grade Silver Cadmium Oxide alloy.
When used for Series operation [up to 40 Amps maximum], the Contacts are suitable for 720 operations per hour and in case of Shunt operation [ for Control Circuit ] , the Contacts are suitable for 1000 operation per hour.The same Contacts can be used in Series as well as in Shunt configurationsThe switching capacity of the Contacts when used for Shunt operation is 15 amps at 400 Volts, AC on highly inductive load and 2.5 amps at 220 Volts DC.These switching capacities in fact are far in excess of what is actually required in practice and hence replacement of Contacts for Shunt may not be necessary for a long time.The body of the Contacts is made of high grade Melamine which is specifically suited for heavy duty operation .The material is non – tracking and is capable of with standing heavy arcing.The FLP/WP Rotary Limit Switch operates in the following manner:The Mechanism or the Drive coupled to the Limit Switch actuates the Contacts through the Worm Gear Drive and the  Cams.When the Mechanism or the Drive approaches the pre determined position, the Cam strikes the Contact finger of the corresponding Contact which in normal condition is in a closed position. This immediately opens the Contacts and the Circuit is broken there by disconnecting the respective Motor from the supply and resulting in the stoppage of the Drive or Mechanism.The Actuator or Cam is provided with a maximum follow-through angle of 60 degrees there by ensuring that the normally closed Contact, which has been opened by the Actuator / Cam, shall remain in the open position for at least 8 full additional revolutions of the Input Shaft.This provision is adequate for most of the Reversing Drives where the Mechanism or Drive comes to a complete stop with in 1/5th of a revolution of the Input Shaft of the limit Switch.
