- Spare Parts Availability: Widely stocked globally; easier to source for MRO and maintenance programs.
- Warranty & Support: Genuine OMRON parts carry manufacturer traceability and quality assurance.
- No Reprogramming: Mechanical counters require zero configuration — install and operate immediately.
Typical Applications
- Production line piece counting and batch control
- Conveyor belt cycle monitoring
- Packaging machinery stroke counting
- Press and stamping machine operation counting
- Injection molding shot counters
- Utility metering and totalizing
- General-purpose industrial pulse counting
System Compatibility
The CSK6-YKW integrates with a wide range of OMRON and third-party automation systems:
- PLC Systems: Compatible with OMRON CJ/CS/NX Series PLC output modules (transistor or relay output)
- Sensors: Works with OMRON E3Z, E2E, and E18 series proximity/photoelectric sensors as pulse sources
- Panel Cutout: Standard 48×24 mm flush-mount cutout (verify with installation drawing)
- Wiring: Standard screw terminal block; compatible with 0.5–1.5 mm² wire
Selection Guide
Use the following criteria to confirm the CSK6-YKW is the right model for your application:
- Digit Count: Need 6 digits (max count: 999,999)? → CSK6-YKW ✓ | Need 5 digits? → CSK5-YKW
- Reset Type: Manual knob reset required? → CSK6-YKW ✓ | Need electrical reset? → Consider H7EC-N
- Counting Speed: ≤30 counts/min? → Electromagnetic type sufficient ✓ | Higher speed? → Electronic counter recommended
- Environment: Standard industrial (IP40 panel front)? → CSK6-YKW ✓ | Harsh/wet environment? → Specify IP65 rated alternative
- Budget: Cost-sensitive MRO replacement? → CSK6-YKW offers best value in class
Quality Assurance & Sourcing

Replacement & Compatibility FAQ
Q: Can I replace CSK6-YKW with CSK5-YKW?
A: Only if your application can tolerate a 5-digit maximum count (99,999). The panel cutout and wiring are similar, but verify dimensions before installation.
Q: Is H7EC-N a direct drop-in replacement?
A: No. The H7EC-N is an electronic DIN-rail counter with different mounting and wiring. It offers more features but requires panel modification.
Q: Can Autonics CE6-YKW replace OMRON CSK6-YKW?
A: In many cases yes — verify coil voltage, terminal pitch, and panel cutout dimensions. Functional performance is comparable.
Q: Do you supply both new and refurbished units?
A: We primarily supply new-in-box genuine units. Refurbished or tested-used units are available on request with full disclosure of condition.
Q: How do I verify authenticity of my OMRON counter?
A: Check the OMRON hologram label, batch code, and date code on the unit. Contact us if you need assistance with verification.
