Model identity
Resolve the SH-S3-1370 versus QM-S3-1370 marking and confirm the full revision or part reference.
Automatic-reset roller limit switch for elevator position and safety-circuit applications. Confirm the full housing label, normally-closed contact requirement, roller travel and mounting interface before replacement.
Five reviewed photographs show the same red-housing structure from independent angles: complete side profile, rating-label side, upper actuator assembly, opposite housing side and transparent terminal-cover view. Some photographs are marked QM-S3-1370 while the backend record uses SH-S3-1370; confirm the supplied revision before ordering.
| Item | Reviewed reference | Order check |
|---|---|---|
| Backend model | SH-S3-1370 | Confirm the complete supplied model |
| Physical marking shown | QM-S3-1370 on supplied photographs | Confirm whether this is the approved housing revision for SH-S3-1370 |
| Contact reference | S3-1370 (1NC) in the reviewed source table | Verify normally-closed operation on the physical unit |
| Rated voltage and current | AC 220 V / 2 A; DC 110 V / 0.3 A | Confirm the utilization category and actual circuit load |
| Movement | 5 ± 1 mm in the reviewed source table | Check roller travel and installed actuation position |
| Operating force | ≤8 N in the reviewed source table | Confirm against the supplied revision |
| Reset | Automatic in the reviewed source table | Verify return action after releasing the roller |
| Backend references | 380 V insulation; −5 to +40 °C; IP20; 1000 A breaking capacity | Confirm each value with exact-model documentation |
| Mechanical interface | Large roller, metal linkage, upper plunger and transparent terminal cover | Compare dimensions, mounting points and terminal clearance |
Resolve the SH-S3-1370 versus QM-S3-1370 marking and confirm the full revision or part reference.
Confirm 1NC contact behavior, AC or DC duty, voltage, current, terminal assignment and controller requirements.
Check roller diameter, 5 ± 1 mm movement, operating direction, automatic return, body size and mounting clearances.
No. The backend and physical photograph use different prefixes. Confirm the supplier's revision mapping before final selection.
The reviewed S3-1370 (1NC) source table states automatic reset, but the supplied physical unit should still be checked.
Compare the complete label, contact state, voltage and load, roller movement, operating force, housing dimensions, mounting and terminal access.
