Form-factor and what lands in the panel
The SS-5GL1129D is the Omron subminiature limit switch listed under the Limit Switches category, with the SS-5GL-2 series form factor typical of the line — a compact SPDT snap-action body with solder/quick-connect terminations that drops into the standard subminiature mounting footprint on a machine bracket or guarding frame. The category-class job of a subminiature limit switch is end-of-travel or presence detection on small mechanisms — door interlocks, cam-actuated position feedback, conveyor diverter arms, and packaging-machine guards — where the housing has to fit inside tight machine geometry and still carry the snap-action contact rating.
Sourcing posture for a live production BOM
For a buyer searching SS-5GL1129D for sale or as an SS-5GL1129D supplier, the practical channel is an RFQ with the order code and quantity attached — the storefront's sourcing reach covers current-production Omron automation parts but pricing and availability are returned at quote time, never asserted up front.
