⚡ XCKJ Series — Heavy‑Duty Metal Limit Switches

The XCKJ series is Telemecanique’s industrial metal limit switch family built to the EN 50041 standard.
These switches are designed for harsh industrial environments, offering high mechanical durability, precise actuation, and positive‑opening safety contacts.

Your uploaded XC document describes them clearly:

“ XC Standard range — Industrial format EN 50041 — Metal, XCKJ ”
“ Fixed body or plug‑in body with 1 cable entry ”

🔧 Key Features

• Metal Zamak housing — High mechanical strength for industrial duty.
• EN 50041 standardised dimensions — Interchangeable with other EN 50041 switches.
• Positive‑opening NC contacts — Safety‑rated mechanical separation.
• Interchangeable heads — Plunger, roller plunger, roller lever, rod lever, multi‑directional.
• 360° head adjustment —
  Document states:

  “ Adjustable throughout 360° in 5° steps, or in 45° steps by reversing the lever. ”

• IP66 protection — Dust‑tight and resistant to powerful water jets.
• High mechanical life — Up to millions of cycles depending on head type.
• Wide temperature range — Suitable for demanding environments.
