Roller-actuated limit switch with a spring-loaded mechanical linkage and covered screw terminals. Confirm the complete label, contact state, operating direction and mounting dimensions before replacement.
Four reviewed photographs show the same S3-B1370 structure from distinct views: complete roller-and-lever assembly, readable side label, covered contact terminals and opposite side profile. The original markings are retained for electrical and model verification.
| Item | Reviewed reference | Order check |
|---|---|---|
| Model | S3-B1370 | Confirm the complete physical label and wide-body version |
| Product type | Roller-actuated elevator limit switch | Confirm the intended limit or safety-circuit position |
| Standard marking | GB 14048.5 | Confirm project and local acceptance requirements |
| AC utilization rating shown | AC-15: 220 V / 2 A | Confirm the actual load category and circuit duty |
| DC utilization rating shown | DC-13: 110 V / 0.3 A | Confirm voltage, load and switching frequency |
| Insulation reference conflict | Physical label: Ui/Ith 500 V; backend record: insulation voltage 380 V | Obtain the supplied revision datasheet before final selection |
| Backend environmental reference | −5 to +40 °C; IP20 | Confirm against the actual unit and installation environment |
| Backend breaking-capacity reference | 1000 A | Do not apply until confirmed by exact-model documentation |
| Mechanical interface | Large roller, lever linkage, return spring and covered screw terminals | Compare wheel diameter, lever travel, mounting and terminal access |
The 500 V marking on the photographed unit does not match the 380 V backend entry. This conflict is intentionally retained for confirmation rather than resolved by assumption.
Confirm AC-15 or DC-13 duty, operating voltage, current, contact state, terminal layout and safety-controller requirements.
Check roller diameter, lever direction and travel, spring return, operating force and available clearance.
Compare body width, mounting holes, terminal-cover access, ambient temperature and required ingress protection.
No. Confirm the wide-body housing, roller and lever geometry, mounting points, contacts and full label.
The supplied photograph shows 500 V while the backend record says 380 V. Obtain an exact-revision datasheet or supplier confirmation before selection.
Provide the old unit's full label, installed position, contact state, circuit duty, body and mounting dimensions, and roller travel.
