SICK deTec / Pilz PSENopt Replacements
Content updated:
Hole spacing, wiring order, and compatibility notes for replacing SICK deTec and Pilz PSENopt safety light curtains with DAIDISIKE DQC models. It covers wiring order, hole-spacing adjustments, and the mounting adapters needed for a replacement assessment.
1) Mounting & Wiring Comparison
Compare the DAIDISIKE light-curtain families and selection limits against the complete deTec or PSENopt order code. A candidate with the required documentary evidence must be selected before mounting or wiring is redesigned.
Replacing SICK deTec or Pilz PSENopt requires careful consideration of mounting holes, wiring order, and electrical compatibility. This section covers the most important elements of the replacement process. The deTec4 Core operating instructions and Pilz PSENopt model documentation illustrate why the exact model and manual must be identified.
| Feature | SICK deTec / Pilz PSENopt | DAIDISIKE DQC |
|---|---|---|
| Mounting type | Depends on exact deTec or PSENopt model and bracket | Compare approved 30 × 30 mm DQC drawing and bracket |
| Hole spacing | Use original dimension drawing and active-field datum | No matching hole pattern established; assess adapter and support requirements |
| Wiring compatibility | Read pinout, OSSD behavior, EDM/reset and enabled functions | Exact-build OSSD and feedback evidence required; no universal pin map |
| Safety evidence | Confirm original Type/PL/SIL and configuration | Catalogue does not establish DQC Type/PL equivalence; obtain evidence before selection |
2) Mounting & Wiring Adjustments
Compatibility must be established for the exact sensor and safety function. Check the following before designing the installation:
- Hole spacing: Compare measured datums with both drawings. Body cross-section and brand family do not establish matching bracket holes.
- Wiring roles: Build a new pin-by-pin plan from the two exact manuals. Check polarity, test-pulse acceptance and safety-input behavior; copying the old wiring order is not valid.
- Mounting adapters: Assess an adapter where drawings differ; confirm stiffness, fastener engagement and the new protective-field position.
3) Common Replacement Mistakes
While performing replacements, avoid these common mistakes:
- Incorrect Hole Spacing: Ensure mounting holes match exactly or use the proper adapters to prevent misalignment.
- Miswiring: Double-check wiring order, especially for OSSD and EDM connections. Incorrect wiring may cause failure to meet safety standards.
- Ignoring the protective field: Check active endpoints and all access routes, then perform the prescribed test-piece verification and a complete stopping-distance assessment.
4) Price Comparison & Value
No like-for-like quotation or measured reliability comparison is provided here. Evaluate the complete retrofit cost after the documented safety requirements have been met:
- Initial cost: Obtain quotes for equivalent documented requirements, including sensor pair, controller, cables and brackets.
- Lifecycle cost: Include revalidation, commissioning downtime, cleaning access, spare parts and maintenance; savings are not established by the family name.
- Compatibility work: Budget for any interface or mechanical redesign needed to preserve the machine’s validated protective function.
Practical questions
Can DAIDISIKE DQC replace SICK deTec or Pilz PSENopt?
No universal replacement equivalence is established. Compare exact model numbers, declared safety Type/PL/SIL, detection capability, response time, active field and electrical functions. DQC requires additional model-specific evidence before it can be considered for a rated safety function.
How do I adjust hole spacing for the replacement?
Overlay both dimension drawings and reference the active optical field, not just overall length. An adapter may be necessary; confirm its stiffness, support positions, connector clearance and the resulting separation distance before installation.
Is wiring compatibility an issue when replacing?
Yes. OSSD and EDM describe functions, not a universal connector or terminal standard. Check pin assignments, output polarity, test pulses, reset and feedback behavior, allowable loads and the selected safety input device before energizing the system.
