Product Description
Benefits & Applications
The Eaton M22-CKC01 is a compact dual auxiliary contact block designed for use with Eaton’s M22 modular pushbuttons, selector switches, and operator devices. Featuring both 1 Normally Open (1NO) and 1 Normally Closed (1NC) contacts in a stacked configuration, this module is ideal for applications requiring paired start/stop functions, interlock logic, PLC input feedback, or enable/disable control signaling.
With its durable construction, high mechanical endurance, and tool-free snap-on mounting, the M22-CKC01 delivers reliable performance in industrial automation, OEM machinery, and commercial control panel environments. The compact CKC-series design helps save panel depth while maintaining secure electrical connections.
Typical Applications
- Start/stop control stations (NO for start, NC for stop)
- PLC input and feedback circuits
- Safety interlock and machine logic
- Motor control and contactor coil logic
- OEM equipment and industrial control panels
Technical Advantages
- 1NC + 1NO stacked auxiliary contacts
- Compact CKC-style design for tight control panels
- Fast, tool-free snap mounting behind M22 operators
- High electrical reliability for low-voltage control and PLC circuits
- Long mechanical life for frequent switching applications
- Fully modular and stackable with additional Eaton M22 contact blocks
Compatibility Notes
The M22-CKC01 integrates with Eaton’s M22 modular operator system, including:
- M22 pushbuttons (illuminated and non-illuminated)
- M22 selector switches and key switches
- M22 emergency stop (E-stop) operators
- M22 contact block adapters and extension modules
If you require a compact 1NO + 1NC auxiliary contact block for control logic or PLC inputs, the M22-CKC01 is the correct Eaton OEM accessory.
Frequently Asked Questions
Q: What is the contact configuration of the M22-CKC01?
The M22-CKC01 provides 1 Normally Closed (1NC) and 1 Normally Open (1NO) auxiliary contacts in a stacked compact housing.
Q: What is the difference between M22-CKC01 and M22-CKC10?
Both offer 1NO + 1NC contacts, but the stacking orientation is reversed. Functionally they are similar, the correct choice depends on your panel layout and operator orientation.
Q: Is the M22-CKC01 compatible with all Eaton M22 operators?
Yes. It fits the full range of M22 pushbuttons, selector switches, key switches, and E-stop devices.
Q: Can additional auxiliary blocks be stacked?
Yes. The modular M22 platform allows stacking multiple NO/NC blocks to create advanced control sequences.
Q: Is this suitable for PLC input circuits?
Absolutely, both contacts provide reliable low-level switching compatible with PLC digital inputs.
