Overview Manuals Cable Planning Signal Setup Weld-Cell Service Product Applications

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.
Description
Where an approved pneumatic actuator sits farther from the control junction in an AC welding cell, D-P4DWZ carries the position signal through its 5 m integral cable.

D-P4DWZ uses red and green indication to expose the preferred sensing region during setup. This visual margin helps distinguish correct piston-magnet alignment from an output that operates only at the edge of detection.

The Z suffix makes D-P4DWZ a different cable configuration from the 3 m L version. Procurement and installation therefore need to account for the longer route without treating the family base number as a complete order identity.
Alternative Names
DP4DWZ D P4DWZ D/P4DWZ
Technical notes
The 5 m lead distinguishes D-P4DWZ from the L variant and raises routing exposure across the weld cell. Preserve the full Z order code, keep the cable above the reference bend radius, and stop installation where it would share a moving carrier or power-conductor route that imposes repeated flexing, tension or electrical noise.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
A project can reach the panel with D-P4DWL. Should D-P4DWZ still be selected for spare cable?
Not automatically. Choose the 5 m Z version only when the approved route needs it; excess cable adds storage, bend and interference exposure without improving the sensing function.
The remote PLC input for D-P4DWZ flickers only while the welding cable is energized. What evidence should maintenance gather?
Record welder source type and current, conductor-to-switch placement, indicator color and PLC state. Stop if the source is outside the documented AC boundary, then escalate the application.
A cable tray forces D-P4DWZ beside motor power wiring for several metres. May shield tape solve the problem?
Do not rely on an improvised wrap. Re-route and separate the two-wire signal from power conductors, or use an engineered wiring method approved for the installation.
After moving D-P4DWZ, the green indication is absent although red appears. Can production restart?
Not on indication alone. Reposition the switch to the preferred green zone and prove stable PLC transitions over repeated controlled cycles before releasing the actuator.
Receiving finds 244 g for D-P4DWZ but the stored record shows the lighter L version. Is this a duplicate weight entry?
No. The official weights differ because Z has a 5 m lead. Correct the item identity and route the shipment under D-P4DWZ rather than overwriting the L record.
A technician wants to shorten the integral lead on D-P4DWZ near the switch body. What is the safe procurement decision?
Keep the factory lead construction intact. If a shorter route is required, order the appropriate L configuration or obtain an approved termination method instead of modifying the molded assembly.
