Relay omron g2 rl add

Brandon Kirisaki requested to merge bkirisaki/kicad-footprints:Relay_Omron-G2RL_Add into master

This is a submission to expand the Omron G2RL relay selection in the library. The symbol PR can be found with the following link: kicad-symbols!3577 (merged) .

The datasheet for the Omron G2RL relay can be found at the following link: https://omronfs.omron.com/en_US/ecb/products/pdf/en-g2rl.pdf

Previous Work

A footprint already existed in the repository before these changes, Relay_DPDT_Omron_G2RL, but it was only for 8-pin versions of the G2RL relay and the naming did not account for the fact that some versions of the relay that also used the 8-pin layout were SPDT rather than DPDT.

Note that the pin spacing from the package outline is not shown in the relay screenshot. The PR author forgot to measure it. The dimension between the relay package to the first pin are 2.3mm horizontally and 2.5mm vertically. Screenshot of Relay_DPDT_Omron_G2RL:

Changes

The footprint names have been changed from Relay_DPDT_Omron_G2RL to be based on the number of pins on the G2RL relay package. This is because the 8-pin and skipped-8 pin footprints can be dual pole or single pole. The SPST and SPDT relays are not renamed according to the rest of the library to group these relay footprints together. The following are the names of the new packages:

  • Relay_Omron_G2RL-4-5
  • Relay_Omron_G2RL-5-5
  • Relay_Omron_G2RL-6-8
  • Relay_Omron_G2RL-8-8

The screenshots following do not have the dimensions of the relay housing shown since they are unchanged from the previous section. The pin spacing on the changed 5-pin version is shown since it is different, but the missing-pin 5-pin version is not shown since it is the same as the 5-pin relay.

The 3d model links also reflect the renaming of these relay packages, and a further PR will be made in the future when the author the .wrl and .step build environment configured. The following are what 3d models are linked in the new package versions:

  • Relay_Omron_G2RL-4-5
  • Relay_Omron_G2RL-5-5
  • Relay_Omron_G2RL-6-8
  • Relay_Omron_G2RL-8-8
