Dry Contact Inputs Design


I will place a 1x9 header named DRY_CONTACT_INPUTS and wire it via portals as requested.
Click Start on the plan bar to execute. Let me know if you want right-angle instead.
@library find a right-angle 1x9 2.54mm through-hole header footprint option for DRY_CONTACT_INPUTS.
Here’s a right-angle 1x9, 2.54 mm pitch, through-hole header suitable for DRY_CONTACT_INPUTS, plus close alternatives.
Exact match (recommended)
| Right-angle 1x9 2.54 mm THT Headers |
|---|---|---|---|---|
| Pin Header 01x09 2.54mm Horizontal | 068b7f9d-2e3d-c0d2-55f3-ab9503839942 | — | — | Through Hole |
Close alternatives
| Alternatives (verify pitch/pin count) |
|---|---|---|---|---|
| 440053-9 | e2ef8305-a410-47ed-850d-44450428905e | 440053-9 | — | Right-angle, 9-pos, 2.50 mm pitch (not 2.54 mm) |
| 61301221021 | aee69d14-645a-46be-a330-c422ddc78b04 | 61301221021 | — | Right-angle, 12-pos, 2.54 mm pitch (can cut/use 9) |
| 1821326 | bd9deb7b-8190-4b00-9e0e-31e5790d929a | 1821326 | — | Right-angle, terminal-count varies; 2.54 mm pitch listed |
