NMCSK1-33 Transparent Triple Magnetic Blowout Limit Switch

Product Introduction:
 

NMCSK1-33 3-Pole Magnetic Blow-out Switch adopts stainless steel 3-roller linked rocker drive structure.Its integrated connecting rod ensures even force on three rollers. When an external limit stopper pushes the rollers sideways, the three inner contacts open and close at the same time.

The metal drive bracket is solid, shock-proof and anti-fatigue, well suited for long-time high-frequency repeated impact triggering on industrial machines.The whole switch is integrally injection-molded from transparent green flame-retardant PC. The housing is heat resistant, fire retardant and superbly insulated.Thanks to the clear casing, users can directly check the open/close status of inner silver contacts to speed up on-site repair and troubleshooting; meanwhile it blocks dust and splashing oil from getting inside to protect internal parts.

This switch comes with three independent sets of silver alloy contacts and separate magnetic blow-out arc extinguishing chambers. As contacts split apart, the built-in permanent magnet creates magnetic field to blow out electric arc instantly. It fundamentally avoids contact burn and welding, greatly extending service life under heavy current loads.

Standard pre-punched mounting holes are reserved on the base. Three-group separated terminals are arranged tidily for easy wiring and tight cable connection against loosening.

With proven magnetic blow-out technology and 3-circuit synchronous control, one mechanical trigger controls three circuits together to fulfill equipment multi-circuit interlock protection needs.High-purity silver contacts resist oxidation and stand millions of on-off cycles, keeping steady contact resistance during long service.

Compact size fits narrow installation space; its 3-roller lever matches various cams and limit stoppers for triggering.Commonly used on small cranes, CNC machines, automatic conveyor lines, elevator safety parts, medium & small injection molding auxiliary equipment for stroke limit protection, 3-way electric interlock and multi-point signal collection.

Application Scenarios

1. The NMCSK1-33 transparent triple magnetic blow-out switch is primarily designed for small, multi-circuit electrical control applications:
  Lifting Equipment: Small overhead cranes, electric hoists, providing synchronous power-off protection for lifting, front/back, and left/right limit switches;
2. Machine Tool Processing: CNC lathes, stamping equipment, providing three-axis limit interlock power-off to prevent mechanical overtravel and collisions;
3. Automated Production Lines: Sorting conveyor lines, non-standard automated equipment, providing synchronous output signals from three position sensors;
4. Elevators and Auxiliary Machines: Elevator safety circuit, door opening limit, and buffer limit three-way interlock protection;
5. Rubber and Plastics Machinery: Small injection molding machines, extrusion auxiliary machines, providing multi-way electrical locking for mold closing, ejection, and safety doors.
