Description
The CKE05C is a Schneider Electric OsiSense XC Standard series limit switch head — specifically the CKE sub-family, designed to mount onto a ZCK E-series limit switch body (the “body” = base with contacts; the “head” = actuator mechanism that screws onto the body). The key phrase “Without Operating Lever” means this head uses a built-in spring-return plunger (顶杆) as its actuator — there is no external lever/roller to attach; the plunger itself is the sensing element (machine cam / door / guard presses the plunger → triggers contacts inside ZCK E body below).
- CKE05C decoding (Schneider XC Standard naming):
- CK = CKE series head (metal construction, for ZCK E body)
- E = compatible with ZCK E body (ZCK E = the base: 1NC + 1NO snap-action contacts, screw terminals, cable gland entry — the “E” body is the most common in XC Standard)
- 05 = head style code: spring-return plunger (Ø10 mm plastic plunger, no lever) — this is the “plunger-only” variant; other 05x codes vary by plunger material (05C = plastic plunger, 05M = metal plunger, 05G = with seal/gasket for IP higher?)
- C = suffix indicating plastic plunger (vs “M” = metal plunger; “G” = with additional seal for IP66/67; “C” here = plastic plunger, standard)
- → CKE05C = CKE head, for ZCK E body, spring-return plunger (plastic), no external lever
- XC Standard system reminder: Schneider XC Standard limit switches are 3-piece modular: Body (ZCK E / ZCK D / ZCK J etc.) + Head (CKExx) + Lever (ZCK Yxx — only if head type needs a lever, e.g., CK11swing lever → needs ZCK Y roller)**. Since CKE05C is plunger type, it needs NO lever — which is what “Without Operating Lever” means. You ONLY need: 1× ZCK E body (e.g., ZCK-E101, ZCK-E201 — E101=cable entry M20, E201=½” NPT etc.) + 1× CKE05C head screwed on top = complete limit switch.
- Why buy head-only? Usually either: (a) replacement — existing ZCK E body in plant, head got smashed by forklift/cam, swap just the head (unscrew 4 screws, lift old head, place CKE05C, screw down — contacts inside body stay wired, no rewiring); (b) spare strategy — stock heads + bodies separately for faster repair; (c) custom combo — pick E body (cable entry / term type) + CKE head (plunger / lever type) per application.
Key Features
- Head Type: Spring-return plunger (Ø10 mm, plastic — C suffix)
- Compatible Body: ZCK E series (ZCK-E101, ZCK-E201, etc. — 1NC+1NO snap-action, screw terminals)
- No Lever Needed: Plunger is the actuator — “Without Operating Lever” = not a lever-type head
- Material (head): Zamak (zinc alloy die-cast base of head) + plastic plunger (C suffix); metal plunger version = CKE05M
- Operating Force (plunger): ~ 12–18 N (typical for XC Standard plunger heads — check Schneider dwg: CKE05 plunger operating force ~15N, release force ~5N)
- Plunger Stroke: ~ 5 mm travel (max) before full actuation; pre-travel ~ 1.5–2 mm to make contact
- Mounting to Body: 4× M4 screws (included with head) — screws onto ZCK E body top (head rotates 90° increments for actuator orientation — 4× 90° positions)
- Sealing (head-to-body): Head gasket included — combined with ZCK E body seal = IP65 (standard); if body is IP66/67 version + CKE05G (sealed head) = IP66/67

⚠️ XC Standard Head/Body/ Lever Combo Rules:
Warranty & After-Sales
- Factory new units: 12 months warranty
- Refurbished units: 3-6 months warranty (fit-check onto ZCK E body + plunger spring-back test)
- Technical support for:
- Head vs Body matching (CKE → ZCK E only; CKD → ZCK D; CKJ → ZCK J — don’t mismatch!)
- CKE05C vs CKE05M vs CKE05G: C=plastic plunger(std), M=metal plunger(oily/abrasive), G=sealed head(for IP66/67 with ZCK E sealed body) — pick per environment
- Complete switch build: 1× ZCK E body (E101=M20 cable, E201=½”NPT, E301=PG13.5) + 1× CKE05C head = complete limit switch — no lever needed
- Head rotation for actuator aim: unscrew 4 M4, rotate head 90° (4 positions), re-tighten — plunger can face N/S/E/W relative to body cable entry
- Replacement scenario: existing ZCK E body wired in panel, head damaged → unscrew 4 screws, lift old CKE, drop CKE05C, screw down → done, no rewiring contacts
- Alternative head types on ZCK E: CKE11 (swing lever, needs ZCK Y lever), CKE12 (flexible rod), CKE14 (roller plunger), CKE16 (cross roller) — if plunger isn’t right for your app, we can cross to correct CKE head
- Optional: ZCK E body (ZCK-E101 M20 / ZCK-E201 ½”NPT / ZCK-E301 PG13.5), CKE05M (metal plunger), CKE05G (sealed), alternative CKE heads (CKE11/12/14/16), ZCK Y levers (if you switch to lever head)

Applications
- Machine Guard / Door Position Detection: Plunger head (CKE05C) mounted on frame, door/cam presses plunger when closed → NC opens (positive opening — safety circuit drops). ZCK E body 1NC+1NO: NC for safety, NO for “door closed” indicator.
- Cam-Follower on OEM Machinery (packaging, conveyor, woodworking): Rotating cam on shaft presses plunger once/rev → pulse to counter or PLC input. Plastic plunger (C) fine for clean cam; if oily/metal-chip environment → CKE05M (metal plunger).
- Replacement Head Swap (Plant Maintenance): Existing ZCK E body (wired, maybe 10 yrs old) — fork truck smashed the plunger head → unscrew 4 M4, lift damaged CKE, drop CKE05C, screw down → 5-min repair, no rewiring contacts. Stock CKE05C as cold spare for all ZCK E bodies in plant.
- Custom Body+Head Combo: Need ½” NPT conduit entry + plunger? → ZCK-E201 body + CKE05C head. Need M20? → ZCK-E101 + CKE05C. European PG13.5? → ZCK-E301 + CKE05C. Head is same; body chooses cable entry.
