CNTD CWL Series Vertical Limit Switch IP66 Waterproof 1NO1NC 6A 250VAC

Original CNTD CWL series vertical limit switches, including popular models CWLCA2-2, CWLCA12-2-Q, CWLCL, CWLD, CWLD1, CWLD2, CWLD3, CWLNJ, and CWLCA32-41. These robust switches feature a die-cast aluminum housing with an IP66 rating, providing excellent water and oil resistance. Equipped with silver alloy contacts, they handle loads up to 6A at 250VAC and 0.3A at 220VDC, with a low initial contact resistance of ≤25mΩ. The adjustable roller lever with engraved scales allows for precise position setting, and the included M20 cable gland ensures a secure seal. Widely used in tower cranes, automotive manufacturing, packaging machinery, and CNC equipment for stroke positioning and overtravel protection.

• IP66 Waterproof & Dustproof: Die-cast aluminum housing with IP66 rating ensures reliable performance in harsh environments with water splashes, oil mist, and dust.
• Precision Adjustable Lever: The roller lever with engraved scales allows for easy and accurate adjustment of the operating position.
• Durable Silver Contacts: High-quality silver alloy contacts provide stable conductivity and long life under frequent switching operations.
• Robust Construction: Reinforced internal design with insulating paper reduces electrical wear, and anti-lost screw design prevents installation hassles.
• Versatile Industrial Use: Ideal for tower cranes, automotive assembly lines, packaging machinery, CNC machine tools, and material handling equipment.
