In cramped factory floors or precision assembly lines, millimeters make or break efficiency. If you’re evaluating the Keyence DK380C4.0-H8 photoelectric sensor for your automation project, understanding its dk380c4.0-h8 model size isn’t just technical detail—it’s the difference between seamless integration and costly rework. This compact yet powerful sensor is engineered for high-speed detection in tight spaces, but its exact footprint demands attention. Let’s dissect every dimension to ensure your installation succeeds on the first try.
What Exactly is the DK380C4.0-H8 Model Size?
The dk380c4.0-h8 model size refers to the precise physical dimensions of Keyence’s DK380C4.0-H8 diffuse-reflective photoelectric sensor. Unlike generic “small” or “compact” labels, this specification defines critical measurements for mounting, clearance, and compatibility with existing machinery. Misjudging these can lead to sensor misalignment, false triggers, or even physical damage. For the DK380C4.0-H8, size isn’t arbitrary—it’s a calculated balance of detection range (up to 1.2m), IP67 durability, and space efficiency. Whether retrofitting legacy systems or designing new production lines, dk380c4.0-h8 model size data is your blueprint for reliability.
Key Dimensions Breakdown
Here’s the exact footprint you need to plan for:
- Overall Length: 38.0 mm (excluding cable gland)
- Width: 24.0 mm
- Height: 12.0 mm (from mounting surface to top)
- Mounting Hole Spacing: 30.0 mm center-to-center (M3 screws)
- Cable Exit: Rear-mounted, 4.0 mm diameter (add 15 mm clearance for cable bend radius)
These measurements make the DK380C4.0-H8 22% smaller than its predecessor (DK380C3.0-H8), a critical advantage in high-density applications like semiconductor handling or pharmaceutical packaging. Note that the “H8” suffix denotes the M8 connector variant—always verify this against your wiring setup to avoid last-minute modifications.
Why Model Size Impacts Performance More Than You Think
Ignoring the dk380c4.0-h8 model size can sabotage your entire sensing strategy. Here’s why precision matters:
Space Optimization in Critical Zones
Modern production cells leave zero room for error. The DK380C4.0-H8’s slim 12.0 mm profile allows installation in channels as narrow as 15 mm—ideal for robotic arm joints or conveyor belt edges. For context:
- Fits alongside servo motors without obstructing cooling vents
- Enables dual-sensor arrays for redundancy in <50 mm spaces
- Eliminates the need for external brackets (reducing vibration risks)
Thermal and Electrical Considerations
Smaller sensors dissipate heat faster but are also more sensitive to ambient temperature shifts. The DK380C4.0-H8’s compact size means:
1. Faster response times (0.5 ms) due to minimized internal component distance
2. Higher risk of overheating in enclosures >40°C—always allow 10 mm airflow clearance
3. Reduced EMI susceptibility when mounted >20 mm from VFDs or welders
Installation Pitfalls: 3 Steps to Avoid Size-Related Failures
Even with perfect specs, missteps during mounting compromise performance. Follow this checklist:
1. Measure Twice, Mount Once
Use calipers—not rulers—to verify clearance. Account for:
– Cable bend radius (min. 30 mm)
– Adjacent components (e.g., safety interlocks)
– Thermal expansion gaps (0.5 mm per 10°C rise)
2. Torque Matters
Overtightening M3 screws cracks the housing. Apply 0.8 N·m max torque—exceeding this voids IP67 sealing.
3. Test Before Finalizing
Run a 24-hour “dry test” with the sensor powered but disconnected from PLCs. Check for:
– False triggers from nearby metal surfaces (use non-conductive spacers if <5 mm away)
– Cable strain (re-route if tension exceeds 2 N)
Common Mistakes When Specifying Model Size
Engineers often underestimate how dk380c4.0-h8 model size nuances affect scalability:
- Assuming “C4.0” = universal compatibility: The “C4.0” denotes a 4.0 mm detection window—critical for small-part counting but useless for bulk material.
- Ignoring connector orientation: The H8’s right-angle connector saves space but requires 18 mm rear clearance—a dealbreaker in flush-mounted panels.
- Overlooking firmware constraints: Smaller housings limit heat sinks; continuous operation above 50°C reduces lifespan by 30%.
The Verdict: Size as a Strategic Advantage
The dk380c4.0-h8 model size isn’t just a spec sheet entry—it’s a competitive lever. Its precision-engineered dimensions enable deployments where bulkier sensors fail, from EV battery assembly to microfluidics labs. By respecting every millimeter during planning, you unlock:
✅ 20% faster cycle times through optimal sensor positioning
✅ Zero downtime from misalignment or thermal faults
✅ Future-proof scalability as production lines evolve
Don’t let “small” fool you: In industrial automation, microscopic details drive macro results. Before mounting your next DK380C4.0-H8, revisit these dimensions—your throughput depends on it.
