Hoisting Limit Switch
⚡ Hoisting Limit Switch — What It Means in the XC Special Range
In Telemecanique Sensors terminology, a hoisting limit switch refers to the XCR, XCKMR, and XCKVR families inside the XC Special Range, all designed specifically for:
- Cranes
- Hoists
- Winches
- Material‑handling machinery
- Lifting platforms
Your uploaded document explicitly states:
“For hoisting and material handling applications, XCR, XCKMR and XCKVR”
(XC Special Range — Selection Guide)
🧩 The Three Hoisting Limit Switch Families (Document‑Supported)
1️⃣ XCR — Rotary Hoisting Limit Switch
Document excerpts:
“With head for rotary movement operators, spring return to off position”
“1 contact actuation position per direction”
Key characteristics
- Rotary head (spring return or stay‑put)
- 1 switching position per direction
- Metal rod or roller lever actuators
- 10 million mechanical cycles
- Pg13.5 cable entry
- IP65
- Ideal for up/down end‑of‑travel on hoists
2️⃣ XCKMR — Metal Multi‑Position Hoisting Switch
Document excerpts:
“With cruciform metal rods… 4 mechanical actuation positions… 2 to 5 electrical positions”
Key characteristics
- Heavy‑duty metal enclosure
- Rotary head with cruciform rod
- Up to 4 mechanical and 5 electrical switching points
- 3 cable entries
- Used for multi‑level hoisting(e.g., floor‑level detection on lifts, multi‑stop cranes)
3️⃣ XCKVR — Plastic Multi‑Position Hoisting Switch
Document excerpts:
“Plastic… with cruciform metal rods… 4 mechanical actuation positions”
Key characteristics
- Reinforced plastic enclosure
- Same multi‑position rotary principle as XCKMR
- Lighter and more economical
- Suitable for indoor hoisting or less severe environments
🔧 Shared Features Across All Hoisting Limit Switches
Document‑supported characteristics:
- Positive‑opening NC contacts
“All limit switches… are positive opening operation.”
- High mechanical durability
XCR: 10 million cycles - Rotary actuation — essential for hoisting drums and pulleys
- IP65 protection
- Compliance with EN/IEC 60947‑5‑1
- Suitable for harsh industrial environments
🏭 Typical Hoisting Applications
- Crane up/down end‑of‑travel
- Hoist upper/lower limit
- Winch drum rotation detection
- Multi‑level lift/gantry positioning
- Material‑handling safety stops
⭐ One‑line summary
A hoisting limit switch in the XC Special Range is a heavy‑duty rotary limit switch (XCR, XCKMR, XCKVR) designed to control end‑of‑travel and multi‑position detection in cranes, hoists, and lifting machinery.
