Description
The Omron CJ1W-TER01 is the End Cover (Terminating Plate / End Plate) for SYSMAC CJ-series PLC racks — including CJ1M, CJ2M, CJ2H, and CJ-series expansion racks. It is a mandatory mechanical closure piece installed at the rightmost end of the CJ I/O rack (after the last I/O unit or special module) to:
- Physically seal the open end of the DIN-rail / backplane assembly
- Prevent accidental contact with live terminals on the last module
- Provide a finished, secure appearance and maintain proper module spacing
The CJ1W-TER01 is a passive plastic end plate — no electrical function, no wiring. It snaps onto the right-side end of the last CJ-series module (or onto an empty end-of-rack slot if using the special end bracket). For most standard CJ racks (CPU + I/O units), one CJ1W-TER01 per physical rack (CPU rack or expansion rack) is required.
✅ Important: This is the standard CJ-series End Plate (TER01) — notthe older C200H / CQM1 end cover. It is not a Terminal Block (TB — those are for CJ I/O modules like 6ES7193-… in Siemens; Omron CJ I/O modules have built-in screw/spring terminals). The “Term Block” in your query refers colloquially to “end-of-rack terminating piece.”
Key Features
- Function: Mechanical end closure for CJ-series rack (CPU rack & expansion racks)
- Compatible With: All CJ-series bases — CJ1M, CJ2M, CJ2H CPUs + CJ1W- I/O modules on CJ1W-PA202/PA205 backplanes
- Mounting: Snaps onto right-side end of last CJ module or onto end-of-rack locator (with CJ1W-II101/II201 expansion couplers — TER01 still used at very end)
- Qty Needed: 1 × CJ1W-TER01 per physical rack (e.g., CPU rack = 1 pc; each expansion rack via II101/II201 = 1 pc)
- Country of Origin: Japan (Omron Corporation)
