Product Description
Benefits & Applications
The Eaton M22-CK01 is a compact dual auxiliary contact block featuring 1 Normally Closed (1NC) and 1 Normally Open (1NO) contacts. Designed for use with Eaton’s modular M22 pushbuttons, selector switches, and operator devices, the M22-CK01 provides dependable control signaling for start/stop circuits, interlocks, PLC input logic, and safety-related functions.
Its tool-free, snap-on design ensures secure attachment and fast installation, while its rugged construction delivers long mechanical life in industrial, commercial, and OEM control panel environments. The M22-CK01 is ideal for applications that require both an enable (NO) and disable (NC) contact within a single, space-saving module.
Typical Applications
- Start/stop pushbutton stations
- Interlock and safety control circuits
- Automation and PLC input signaling
- Motor control and contactor coil logic
- OEM equipment and industrial control panels
Technical Advantages
- 1NC + 1NO dual contact configuration
- Tool-free, snap-on assembly for quick installation
- High electrical reliability for control and PLC circuits
- Long mechanical and electrical endurance
- Modular design supports stacking with additional M22 contact blocks
- Compatible with all Eaton M22 operator devices
Compatibility Notes
The M22-CK01 is part of Eaton’s M22 modular operator platform and is compatible with:
- M22 pushbuttons (illuminated and non-illuminated)
- M22 selector and key switches
- M22 emergency stop operators
- M22 mounting bases and expansion adapters
If your operator station requires both NC and NO auxiliary contacts for interlocks, stop/start circuits, or PLC logic, the M22-CK01 is the correct Eaton OEM accessory.
Frequently Asked Questions
Q: What is the contact configuration of the M22-CK01?
The M22-CK01 provides 1 Normally Closed (1NC) and 1 Normally Open (1NO) contact in a single module.
Q: Which Eaton devices is the M22-CK01 compatible with?
It snaps onto all Eaton M22 pushbuttons, selector switches, key switches, and emergency stop operators.
Q: Is the M22-CK01 suitable for PLC input circuits?
Yes. Both contacts provide reliable low-level switching suitable for PLC digital inputs and automation control signals.
Q: Can I stack the M22-CK01 with additional auxiliary contacts?
Yes. The modular M22 system supports stacking multiple NO and NC blocks to build more complex control logic.
Q: What is the difference between the M22-CK01 and the M22-CK10?
Both provide one NO and one NC contact, but in reverse stacking order. Functionally they are similar; selection depends on the physical layout required inside your control panel.
