Product Overview
The Omron CJ1W-ID262 is the CJ-series 64-point DC24V digital input unit with two MIL connectors on the front face. Pick the ID262 when a CJ1 / CJ2 / NJ panel needs a high-density 24 V input module without sacrificing the easy-to-wire MIL connector. It draws 4.1 mA per point at 24 VDC (which is the typical ON-state current for most 3-wire PNP sensors, prox switches, and panel-mounted pushbuttons), and runs on 90 mA from the 5 VDC CJ backplane.
Polarity-free input
The ID262 is polarity-free -- input power can be wired in either direction. Most CJ1W input units require NPN (sinking) sensors; the ID262 (along with the ID261) is the common-denominator pick when a panel mixes NPN and PNP sensors on the same input module without DIP switches. Wire each sensor's +V and 0V to the matching COM terminal regardless of polarity. The same spec applies to the matching 32-point ID231 and ID232 in the family.
4 commons, 50% simultaneously ON
The 64 inputs split into 4 commons of 16 points each. At 24 VDC, the ID262 spec is 50% of points simultaneously ON (8 of 16 per common, 32 of 64 total) -- this is a thermal limit on the connector pin density, not a spec on the input chips. For a panel with 64 active sensors, pick a second ID262 or step down to the 32-point ID231 / ID232 to keep the simultaneously-ON count inside the envelope.
Response time and PLC setup
ON / OFF response is 8.0 ms by default; the PLC Setup can switch any input unit to a 0-32 ms selection in CX-Programmer. The bare minimum (0 ms) reduces to 120 us ON / 400 us OFF because of internal element delays. Pick a faster input -- the ID212 at 15 us or the IDP01 high-speed interrupt unit -- when a build needs sub-millisecond response on more than a handful of points.

Best-Fit Applications
- 64-point DC input module for a CJ1 / CJ2 / NJ panel that wires bulk sensors through pre-made MIL cables from a remote junction box
- Mix NPN and PNP sensors on the same module -- the ID262 polarity-free design accepts either wiring without DIP switches
- Use the 50% simultaneously-ON envelope for steady-state panels (e.g. conveyor status, light stacks, pushbuttons), step down to ID231 / ID232 for >50% active inputs
- Pick this when the 32-point ID232 is not enough points but the spare slot is on the deep CJ rack -- the ID262 keeps a 64-point density without sacrificing the MIL connector footprint
- Add a fast IDP01 high-speed interrupt unit or the CJ1W-ID212 15 us input alongside the ID262 when a few points need sub-millisecond response
Buying Checklist
- Pick CJ1W-ID262 for a 64-point DC24V input module with two MIL connectors and polarity-free wiring at 90 mA 5 VDC.
- Pick CJ1W-ID261 instead for the same form factor with the older dedicated NPN (sinking) wiring style (the ID262 supersedes for new builds).
- Pick CJ1W-OD262 instead for the matching 64-point PNP (sourcing) OUTPUT unit (the OD26x family for outputs).
- Pick CJ1W-ID232 instead for a 32-point DC input on a single MIL connector when a 64-point module is too dense.
- Pick CJ1W-IDP01 or CJ1W-ID212 instead when sub-millisecond interrupt response is needed -- the ID262 is a 8 ms default.
- Confirm 50% simultaneously-ON envelope -- a 64-point panel with all sensors active most of the time needs a second ID262 to stay within the thermal limit.

FAQ for CJ1W-ID262
Is the CJ1W-ID262 NPN (sinking) or PNP (sourcing)?
Neither, and both. The ID262 is polarity-free -- the field power can be wired in either direction, so NPN (sinking) and PNP (sourcing) sensors both work on the same module without DIP switches. Wire each sensor's +V and 0V to the matching COM terminal regardless of which side of the field supply that sensor shares. This is the same flexibility the CJ1W-ID261 and CJ1W-ID232 carry -- the older dedicated NPN-only units (ID211 / ID231) require NPN wiring and a fixed polarity.
How many sensors can be on at the same time?
Up to 32 of the 64 inputs simultaneously ON at 24 VDC (8 of 16 per common). This is a thermal limit on the connector pin density and the internal PCB trace heating, not a limit on the input chips. For a panel with >32 sensors active at steady state, split into two ID262 modules on separate commons or step down to the 32-point ID231 / ID232 modules so each commons stays at 8 / 16 ON. For higher active counts use the ID261 / ID232 family instead -- the thermal envelope is the same.
How fast is the CJ1W-ID262?
8.0 ms ON and 8.0 ms OFF by default. The PLC Setup in CX-Programmer can switch any CJ1W input module to a 0 to 32 ms selection, but the bare minimum (0 ms) actually settles to 120 us ON and 400 us OFF because of internal element delays. The ID262 is the typical pick for status and sensor inputs. For sub-millisecond response pick the CJ1W-ID212 at 15 us ON / 100 us OFF or the CJ1W-IDP01 high-speed interrupt unit (with interrupt task in the CPU).
What MIL connector goes on the ID262?
Two FCN-360C040-J2 / OTAX N360C040J2 40-pin MIL connectors (one for CN1 and one for CN2) sit on the front face of the ID262. These are the same connectors used by the CJ1W-ID261, CJ1W-OD261, CJ1W-OD262 and the ID231 / ID232 siblings. Pre-wire the field with the XG4M-4030 / XG5M-N1632 cable family or solder a C500-CE404 40-pin right-angle connector kit for a custom harness. The 64 inputs split across the two MIL connectors by 32 / 32 (16 points per common x 2 commons per connector).
