People Electric · Travel Limit Switch
Product overview
People Electric LXK3-20 travel switches provide operation, limit and signal-interlock functions in control and auxiliary circuits. This listing covers the S vertical and H horizontal enclosed versions in the manufacturer motion table, with selectable actuator forms for the actual machine.
Technical selection summary
| Manufacturer / series | Original People Electric LXK3-20 |
|---|---|
| Contacts | 1NO + 1NC; specification code 20 in the original model diagram |
| Enclosure codes | S: vertical enclosure with bottom cable outlet; H: horizontal enclosure with bottom and side cable entries. Open K version is outside this listing. |
| Actuator codes | Z plunger; L roller plunger; B roller arm; T adjustable roller arm; J adjustable metal rocker; D flexible rocker; H1/H2/H3 double-wheel cross arrangements; W universal actuator |
| Reset action | L/B/T/J/D/W are described as auto-reset; H1/H2/H3 cross types are without auto-reset. Confirm Z plunger operation and required direction. |
| AC-15 operational duties | 380V / 0.8A; 220V / 1.4A; 110V / 2.8A |
| DC-13 operational duties | 220V / 0.15A; 110V / 0.3A |
| Thermal / insulation rating | Ith 5A; Ui 500V |
| Short-circuit / fuse reference | Source lists 1000A withstand and RL1-15/10 fuse. Confirm the required protective arrangement; no independent short-circuit tripping is claimed. |
| Operation frequency / electrical life | 1,200 operations/hour; AC life 1,500,000 operations; DC life 300,000 operations, as stated |
| Position repeatability | Difference between maximum and minimum position over 10 movements ≤0.05mm as stated |
| Enclosure protection | IP25 as stated; match the exact enclosed version and installation |
| Environment | Altitude <2,000m; -5 to +40°C, daily average ≤35°C; RH ≤50% at +40°C; pollution degree III; installation category III |
The selectable scope is limited to the S/H enclosed LXK3-20 versions explicitly listed in the motion table. Confirm the actuator direction, return action, mechanical travel, cable-entry orientation and exact mounting dimensions before order. The 5A thermal rating differs from the AC-15/DC-13 operating-current ratings.
Typical applications
- Mechanical position, limit and interlock inputs in industrial control circuits.
- Machines requiring a specific plunger, roller, rocker or cross-arm actuator.
