M22-K01
ใช้งานอยู่M22 1NC Contact Block
Eaton M22 series 1NC contact block.
การใช้งานทั่วไป
1NC contact block for stop and safety circuits. The NC contact breaks the circuit when pressed — fail-safe design. Wire in series with motor contactor coil. Keep spares on hand — contact blocks are the most common failure point.
ความเข้ากันได้
Same compatibility as M22-K10. NC version. Fits all M22 operators.
ซ่อมบำรุง
NC contacts are safety-critical — replace every 5 years as preventive maintenance on e-stop circuits regardless of test results.

Mounting: Snap onto the rear of any compatible button body in the same series. The latch clicks audibly when properly seated. Some models require a mounting adapter.
Wiring: Terminals are marked NO (11/12) or NC (21/22). Use 0.5-2.5mm² wire with ferrules. Tighten to 0.8 Nm. Verify with a multimeter before energizing.

การแก้ไขปัญหา
Intermittent switching
Silver contacts are pitted from arcing. Replace the contact block — they are consumable parts. If arcing is severe, check that the switched load doesn't exceed the contact rating (typically 6A at 120VAC).
Contact block won't snap onto button body
Verify the contact block series matches the button head series (e.g., Schneider ZB4 blocks fit ZB4 heads only, not ZB5). Check for debris or damage on the mounting tabs.
