Contact SupplierTwo Way Series Limit Switch: “STERLING” Two Way Series Limit Switch is used to prevent over travel or over traverse. The Limit Switch is fitted with 2 sets of contacts which remain normally closed and supply power directly to the 2 phases of Motor in either direction. When the lever is moved over a projecting member fixed at a pre-Determined position on either side of the gantry, the power supply to the motor is cut off. The contacts are automatically reset when the lever returns to `Zero’ position due to spring action.
The contacts are rated for 60 Amps at 415 Volts A. C. 50 cycles supply system.The side covers are of cast iron. The top and bottom covers are of sheet steel. The lever is of Mild Steel fitted with M. S. Roller.
Hoist Series Limit Switch:
“STERLING” Hoist Series as differential Limit Switches is used to prevent over hoisting. The Limit Switch will normally remain `ON’ due to the weight connected to the lever. When the snatch block reaches the highest position the weight pulling the lever down is moved up on the snatch block, hence the lever is released and the two snap action contacts cut off 2 phases of the motor thereby stopping the hoisting motion. The contacts are automatically reset when the snatch block is lowered.
The contacts are rated for 60 Amps at 415 Volts A. C. 50 cycles supply system. Heavy Duty Hoist Limit Switch with contacts rated for 150 Amps at 415 Volts A. C. 50 cycles with arc chutes and blow out coils can also be supplied.
Rotary Shunt Limit Switch:
“STERLING” Rotary Shunt & geared Limit Switches is also used to prevent over hoisting. One set of contacts cut off supply to the coil circuit of the HOIST contactor, after about 6 revolutions of the spindle the other set of contacts cut off supply to the coil circuit of DOWN contactor. The contacts are automatically reset when the spindle rotates in the reverse direction.
The position of the switch operation is adjustable within 6 revolutions with one over turn in either direction. The spindle can be chain or gear driven with required reduction ratio to suit individual requirement. The Limit Switch is housed in totally enclosed fabricated steel housing with contacts rated for 10 Amps at 415 Volts A. C. 50 cycles supply system.
