Telemecanique Sensors XCKN2102G11 Limit Switch: Plastic Roller Plunger for Compact Machine Position Feedback
The Telemecanique Sensors XCKN2102G11 limit switch is a compact-format device in the XC Standard family, engineered for dependable mechanical position detection in industrial automation. It is defined as an XC Standard limit switch with a plastic roller plunger, 1 NC + 1 NO contacts, and snap action switching, supported by a Pg 11 cable-gland entry.
In practical control architectures, a limit switch is often the simplest way to convert a physical machine position into a discrete electrical state for a PLC input. The value of the Telemecanique Sensors XCKN2102G11 limit switch is that it packages this function into a compact body that is easy to mount “by the body,” while keeping the interface predictable for common cam-driven actuation scenarios.
Technical Identity and Construction
This model is specified with a fixed body and a plunger head, using a linear movement of the operating head. The operator type is listed as a spring return roller plunger (plastic), making it well-suited for repeated contact where rolling action helps reduce friction compared with a plain plunger.
- Device short name: XCKN
- Body material: Plastic
- Head material: Plastic
- Contacts: 1 NC + 1 NO
- Contact operation: Snap action
Because the Telemecanique Sensors XCKN2102G11 limit switch uses snap action, the electrical transition is designed to be decisive once the actuator crosses the switching threshold. This helps the control system avoid ambiguous intermediate states that can occur when mechanical motion is slow or slightly vibrating near the trip point.
Actuation Method and Approach Geometry
The switch actuation is specified as by 30° cam, and the approach type is listed as lateral approach, 2 directions. This combination is common in conveyor and packaging mechanisms where a cam plate sweeps across the roller from either direction depending on machine layout. With lateral two-direction approach, the mounting orientation can be more flexible during machine design or retrofit.
Electrical Termination, Cable Entry, and Installation Discipline
From an installation standpoint, the Telemecanique Sensors XCKN2102G11 limit switch uses screw-clamp terminals with a stated clamping capacity of 1 x 0.34…2 x 1.5 mm². Cable entry is listed as 1 entry tapped for Pg 11 cable gland.In commissioning practice, correct gland selection and correct conductor preparation are what preserve sealing performance and reduce the risk of conductor pull-out during maintenance.
The contact code designation includes industrial control categories such as A300 / AC-15 (e.g., Ue 240 V, Ie 3 A) and R300 / DC-13 (e.g., Ue 250 V, Ie 0.1 A), with Ithe 10 A. This gives engineers a standards-based frame for load selection, especially when switching control loads rather than purely resistive loads.
Environmental Profile for Real Installations
For many machine builders, environmental resistance determines whether a limit switch remains stable over time. The Telemecanique Sensors XCKN2102G11 limit switch is listed with IP65 protection and IK04 impact rating, along with shock and vibration resistance figures commonly referenced against IEC test methods. These values support use in typical dusty or splash-prone areas, provided the cable gland is installed correctly and the mounting is rigid.
