It carries the EN 50041 design D actuator head with a 200 mm plastic twist rod, meaning a passing object that strikes the rod at an angle rotates the head and trips the contacts — the typical fit is a hinged guard, a flap on a conveyor, or any hinged panel where direct plunger actuation is impractical (cites:,). ## Switching envelope across AC and DC voltages Thermal current is rated 10 A and the device uses snap-action contacts, so the headline rating is the continuous 10 A figure — every per-voltage figure below must be read against that ceiling (cites:,). AC ratings step down with voltage: 6 A at 240 V, 3 A at 24 V, 0.55 A at 125 V; DC ratings fall faster because DC has no zero-crossing to assist arc extinction — 0.27 A at 250 V and 0.12 A at 400 V (cites:,). Insulation voltage is rated 400 V, so the device fits a 400 V three-phase control circuit on the upper bound; degree of pollution 3 is consistent with an industrial enclosure environment rather than a clean room (cites:,). ## Repeat accuracy, sealing, and mechanical duty Repeat accuracy is 0.05 mm on the actuation point, which is the figure that matters when the switch is used as a position reference rather than a simple end-of-travel — at 0.05 mm the part is suitable for repeatable gate-position sensing on a machine tool or a packaging line, not for precision gauging (cites:). Sealing is IP65/IP67 on the housing, so the device tolerates water jets and temporary immersion — the practical fit is a washdown area, an outdoor conveyor, or a food-and-bev line where the enclosure gets hosed down at shift end (cites:). ## Wiring and panel-side integration Cable entry is a single M20 x 1.5 gland, and the housing is a narrow metal block 40 mm wide by 281 mm long with cathodic dip coating — the long envelope is the rod actuator's swept length, not the switch body, and the dip coating lets it sit in a damp panel without the paint flaking (cites:,). Operating temperature range is -25... +85 °C and storage -40... +90 °C, with mounting in any position by screw fixing — the part can be re-oriented to suit the swing direction of the guard without re-drilling, which matters when retrofitting an existing bracket (cites:,). ## Where it is used and what to keep in mind Mechanical position switches in the SIRIUS 3SE5 family are the standard fit for guard-door monitoring, position feedback on packaging and material-handling machinery, and end-of-travel limits on conveyors and hoists — the twist-rod actuator here is the variant picked when the moving part is a flap or a hinged panel rather than a sliding carriage (cites:,). The switch is rated for snap-action contacts without positive opening — meaning the contacts may weld closed under a fault, so the safety-circuit designer must not rely on this part alone for a Category 1 or higher safety stop; pair it with a monitored contactor or a safety relay if the guarding is personnel-protective (cites:,). ## Lifecycle read and how to source it Lifecycle stage is recorded as current, with substance prohibition compliance dated 07/01/2006 — so the part is on the active line and the material declaration pre-dates the RoHS recast (cites:,). For volume requirements the part is quoted to order through independent distribution against the BOM — lead time, MOQ, and any price-break ladder are confirmed at RFQ rather than carried as standing stock (cites:).","metaTitle":"Siemens 3SE5112-0CH82 SIRIUS Limit Switch, 10 A, IP65/IP67","metaDescription":"Siemens 3SE5112-0CH82 SIRIUS mechanical position switch, 10 A thermal, 400 V insulation, IP65/IP67, twist rod actuator.
