Keyence SL-V / GL-R Compare/Compatibility
Content updated:
Selection and price bands. This guide compares the Keyence SL-V and Keyence GL-R models with DAIDISIKE's DQC safety light curtains. Learn about compatibility, key features, and price bands for the optimal selection in your machine safety applications.
1) Keyence SL-V vs GL-R: Basic Features
The DAIDISIKE light-curtain series overview is the starting point for finding a candidate with the required documented safety classification. The comparison here evaluates Keyence-specific replacement questions, not automatic equivalence.
Both Keyence SL-V and Keyence GL-R have variant-specific specifications. Compare the official SL-V specifications and GL-R specifications with the DQC catalogue and safety-documentation limits.
| Feature | Keyence SL-V | Keyence GL-R | DQC (DAIDISIKE) |
|---|---|---|---|
| Detection capability | Variant-specific; includes 14 and 25 mm models | 14 / 25 / 45 mm by F / H / L variant | Confirm declared detection capability; catalogue beam-pitch terminology is inconsistent |
| Response time | Maximum for exact height and connection | Maximum for exact height, mode and connection | Catalogue ≤15 ms; confirm selected configuration |
| Mounting type | Exact sensor and bracket drawings required | Exact sensor and bracket drawings required | Catalogue 30 × 30 mm body; no universal adapter fit established |
| Detection range | Check selected suffix and approved accessories | Check F/H/L variant and approved accessories | Catalogue 0.3–3 m standard; 0.3–6 m custom |
| Price comparison | Matched quote required | Matched quote required | Include hardware, safety logic and revalidation; no cost ranking established |
2) Keyence SL-V / GL-R and DQC Compatibility
When replacing Keyence SL-V or GL-R with DAIDISIKE DQC, compatibility considerations include:
- Mounting: Compare the exact bracket holes, active-field endpoints and connector envelope. No stocked universal Keyence-to-DQC adapter or shared hole pattern is established here.
- Wiring: Compare pin assignments, supply, polarity, output test pulses and safety-input compatibility. Confirm DQC’s actual dual-channel OSSD and feedback architecture in the selected build.
- Detection range: DQC lists 0.3–3 m standard and 0.3–6 m custom. Check accessory derating and confirm detection capability independently of beam pitch.
3) Selection Considerations
The decision to use Keyence SL-V, GL-R, or DAIDISIKE DQC largely depends on application needs. Consider the following:
For Higher Resolution
- A 10 mm DQC beam-pitch option must not be treated as proven 10 mm detection capability without its declaration and test evidence.
- Compare the actual maximum response time and required safety classification before considering a tighter installation.
For Cost-Effective Solutions
- A DQC candidate needs documented detection capability and safety functions comparable with the original requirement; equivalent performance is not assumed.
- Request a quote only after the exact optical span and safety-function requirements are defined.
4) Pricing & Cost Benefits
No matched quotation or measured cost comparison is available for the same requirements. Assess the following cost items before deciding whether a retrofit is economical:
- Initial equipment cost: Compare exact sensor pairs, required controller, cables and bracket kits in current quotations.
- Lifecycle cost: Include validation, cleaning access, spare parts, maintenance and installation downtime. Savings are project-specific.
- Model options: Check availability and documentation for each required function; both manufacturers offer variant-specific configurations.
Practical questions
What's the price difference between Keyence SL-V and DAIDISIKE DQC?
No matched quotations or measured lifecycle cost comparison are available here. Compare complete quotes for equivalent documented requirements, including cables, brackets, safety logic, validation, spares and downtime.
Can DQC replace Keyence SL-V or GL-R?
Only after an application-specific assessment. DQC is not established here as a Type 4 or PL-rated equivalent, and dual-channel OSSD availability requires confirmation for the exact build. Matching a housing or nominal detection distance does not approve a replacement.
How do DQC and Keyence models compare in terms of resolution?
SL-V and GL-R have variant-specific detection capabilities. GL-R includes 14, 25 and 45 mm variants. The DQC catalogue uses beam-pitch and resolution terminology inconsistently; obtain a declared detection capability and its test evidence before comparing.
Brand names such as Keyence, SL-V and GL-R are the trademarks of their respective owners and are used here only for nominative comparison and compatibility reference.
