Features:
- Extended cable reach: The Z order code provides a 5 m integral lead for distant cabinet or junction locations.
- Preferred-zone indication: Green light identifies a stronger setup position within the red detection band.
- Defined welding use: Magnetic resistance is tied to documented single-phase AC welding conditions rather than every welding technology.
D-P4DWZ is selected when an approved actuator and load circuit need the D-P4DW sensing behavior with the longest standard grommet lead.
The longer cable can simplify a remote connection but increases the importance of fixed routing, separation and mechanical protection.
Exact-model acceptance must retain the Z suffix because weight, lead reach and installation exposure differ from D-P4DWL.
Apter Power can help confirm the SMC D-P4DWZ Magnetic-Field-Resistant Solid-State Auto Switch, supported actuator, 5 m cable route and load circuit before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Route length: Use the 5 m configuration only when the full path can be supported without a stressed service loop.
- Movement boundary: Keep the standard lead out of continuous-flex carriers unless SMC provides a suitable moving-cable solution.
- Power separation: Maintain distance from welding power and other high-voltage conductors along the complete route.
- Receiving identity: Require the Z suffix on the marked item and purchase documents.
- Series load: Connect the non-polar two-wire switch only to a compatible relay or PLC input circuit.
- Green-zone target: Position the switch inside the preferred indication range during controlled actuator movement.
- Bracket match: Use the actuator-specific mounting method rather than improvising a universal clamp.
- Functional proof: Cycle the actuator through normal travel and verify both local indication and the remote input.
- Source type: Reconfirm the welder is within the stated single-phase AC application before blaming field interference.
- Debris control: Remove magnetic chips and spatter accumulation that can disturb the sensing field.
- Cable inspection: Look for crushing, hardened insulation and repeated bend damage across the longer run.
- Input diagnosis: Separate leakage-current effects from true switch-on behavior at the receiving circuit.
- Remote weld-cell cabinets: Carries an actuator-position signal to a junction located beyond a 3 m lead route.
- Large welding fixtures: Supports position feedback on approved cylinders distributed across a wider tool.
- Clamp position monitoring: Indicates piston position near documented alternating magnetic disturbance.
- Retrofit cable rationalization: Replaces an installed Z-length switch without adding an unapproved intermediate splice.
