The Omron SS-5GL13D2 is a sub-miniature snap-action limit switch in the limit switch category, listed as a current-production item per the part record. Contact form is Single Pole, Double Throw (SPDT) — one common, one normally open, one normally closed — the workhorse configuration for position-feedback and end-of-travel sensing on machine guarding, conveyors, and door interlocks.
Why an SPDT limit switch is the buyer's default
SPDT gives the wiring designer both an NO and NC output from the same actuator, so the same switch can drive a safety input and a status indicator without a second contact block — replace the part, the logic table stays the same. For an MRO planner, that matters at fault time: one part number covers the normally-closed safety loop and the normally-open aux signal, so the storeroom can stock a single SKU instead of two single-throw variants.
Sourcing posture for the BOM line
Lifecycle stage is recorded as current, so the SS-5GL13D2 is not on a discontinuation watch and the procurement decision is a standard quoting exercise against the BOM quantity rather than a last-time-buy. Pricing and lead time are confirmed at quote time through independent industrial distribution; no stock count, channel authorization, or shipment promise is asserted on the page itself.
