Product Description
Benefits & Applications
The Eaton M22-CK10 is a compact dual auxiliary contact block designed for use with Eaton’s modular M22 pushbuttons, selector switches, and operator devices. Featuring a combination of 1 Normally Open (1NO) and 1 Normally Closed (1NC) contact, the M22-CK10 is ideal for control circuits that require both “start” and “stop” or “enable” and “disable” functions in a single, space-saving module.
Built for industrial environments, this contact block offers high mechanical endurance, reliable low-level switching, and a secure snap-on mounting system. It is widely used in control panels, OEM machinery, packaging equipment, material handling systems, and building automation where dependable signaling and feedback are essential.
Typical Applications
- Start/stop pushbutton stations (NO for start, NC for stop)
- Interlock and safety circuits
- PLC input and feedback signals
- Motor control and contactor signaling
- Industrial automation and OEM control panels
Technical Advantages
- 1NO + 1NC auxiliary contacts in a single compact module
- Tool-free, snap-on design for quick installation
- High electrical and mechanical endurance for frequent operation
- Clean, reliable switching for low-voltage control and PLC inputs
- Part of Eaton’s modular M22 operator system
- Space-efficient design for dense control panel layouts
Compatibility Notes
The M22-CK10 is part of Eaton’s M22 modular operator platform and is designed to mount directly behind:
- M22 momentary and maintained pushbuttons
- M22 selector and key switches
- M22 emergency stop (E-stop) operators
- M22 mounting bases and expansion adapters
If your panel uses Eaton M22 operators and requires a combined 1NO + 1NC auxiliary contact in a single module, the M22-CK10 is the correct OEM accessory.
Frequently Asked Questions
Q: What contact configuration does the M22-CK10 provide?
The M22-CK10 provides 1 Normally Open (1NO) and 1 Normally Closed (1NC) contact in one compact auxiliary block.
Q: Which Eaton devices is the M22-CK10 compatible with?
It is compatible with the full range of Eaton M22 operators, including pushbuttons, selector switches, key switches, and E-stop devices.
Q: Can I stack the M22-CK10 with other M22 contact blocks?
Yes. The M22 system is modular, so the M22-CK10 can be combined with additional NO/NC contact blocks to build more complex control logic.
Q: Is the M22-CK10 suitable for PLC input circuits?
Yes. Both the NO and NC contacts are suitable for low-voltage PLC input and control circuits.
Q: What is the difference between M22-CK10 and M22-KC01?
Both provide a 1NO + 1NC combination, but they differ in . Always check your existing contact block part number and mounting orientation when ordering replacements.
