Positive opening is the load-bearing detail here: the contact is mechanically forced open by the actuator travel, independent of spring return, which is what the EN 50041 / IEC 60947-5-1 positive-opening spec exists to certify on a safety-rated position switch. ## What the ratings tell the panel builder Repeat accuracy is 0.05 mm, which is the figure that decides whether the switch holds its trip point across millions of cycles on a high-repetition machine; the contact mechanism is slow-action, so the make/break is not bounce-sensitive the way snap-action switches are. Mechanical shock rating is 30 g / 11 ms per IEC 60068-2-27, paired with an IP66/IP67 sealing and a cathodic dip-coated metal enclosure, which together let the body survive washdown and the impulse loads seen on presses, packaging lines, and outdoor conveyor skids without corroding through at the gland plate. Operating temperature spans -25 to +85 °C with a storage envelope of -40 to +90 °C, so an unpowered spare on the shelf stays within spec for a maintenance float, and a unit mounted near a hydraulic manifold or furnace-skid housing stays within its switching envelope on the hot side. ## Mounting and wiring at the gland plate Fastening is screw-fixing in any mounting orientation, and the pollution degree is class 3, which is the rating for industrial environments with conductive contamination present — the kind of duty that needs the IP66/IP67 sealing at the cable entry rather than just at the body face. The actuator head is a metal lever with a plastic roller — the roller is the consumable surface that takes the cam or dog impact, so it is the part to specify as a replacement item on a long-running line rather than the switch body itself.","metaTitle":"Siemens 3SE5122-0BE01 SIRIUS limit switch, 10 A, IP66/67","metaDescription":"Siemens 3SE5122-0BE01 SIRIUS mechanical position switch, metal block-wide body, 10 A thermal, IP66/IP67, positive opening per EN 50041.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Limit Switches"],"specifications":{"Solid":"1x (0.5 ... 1.5 mm²), 2x (0.5 ... 0.75 mm²)","title":"3SE5122-0BE01","description":"Position switch Metal enclosure 56 mm wide Device connection 3x (M20x 1.5) 1 NO/1 NC slow-action contacts Roller lever, Metal lever and plastic roller 22 mm","During Storage":"-40 ... +90 °C","Repeat Accuracy":"0.05 mm","Thermal Current":"10 A","lifecycle_stage":"current","Active Principle":"mechanical","Cable Entry Type":"3x (M20 x 1.5)","During Operation":"-25 ... +85 °C","Fastening Method":"screw fixing","Circuit Principle":"slow-action contacts","Mounting Position":"any","Product Brand Name":"SIRIUS","Degree Of Pollution":"class 3","Product Designation":"Mechanical position switches","Width Of The Sensor":"56 mm","at 24 V rated value":"3 A","at AWG cables solid":"1x (20 ... 16), 2x (20 ... 18)","protection class IP":"IP66/IP67","Length Of The Sensor":"119 mm","at 125 V rated value":"0.55 A","at 240 V rated value":"6 A","at 250 V rated value":"0.27 A","at 400 V rated value":"0.12 A","Design Of The Housing":"block, wide","at AWG cables stranded":"1x (20 ... 16), 2x (20 ... 18)","Design Of The Interface":"without","Coating Of The Enclosure":"cathodic dip coating","Shape Of The Switch Head":"roller","Material Of The Enclosure":"metal","according to IEC 60068-2-27":"30g / 11 ms","Of The Supplied Basic Switch":"3SE5122-0BA00","Substance Prohibitance (Date)":"07/01/2006","Type Of Electrical Connection":"screw-type terminals","Insulation Voltage Rated Value":"400 V","Design Of The Actuating Element":"Roller lever, metal lever, plastic roller","Design Of The Switching Contact":"mechanical","Operating Frequency Rated Value":"50 ... 60 Hz","Design Of The Switching Function":"positive opening","Standard-Compliant Actuator Head":"EN 50041","Product Function Positive Opening":"Yes","Suitability For Use Safety Switch":"Yes","Of The Supplied Switching Contacts":"3SE5000-0BA00","Surge Voltage Resistance Rated Value":"6 kV","reference code according to IEC 81346-2":"B","Finely Stranded With Core End Processing":"1x (0.5 ... 1.5 mm²), 2x (0.5 ... 0.75 mm²)","Of The Supplied Empty Enclosure With Cover":"3SE5122-0AA00","Design Of The Housing According To Standard":"No","Number Of Switching Contacts Safety-Related":"1","Material Of The Enclosure Of The Switch Head":"plastic","number of NC contacts for auxiliary contacts":"1","number of NO contacts for auxiliary contacts":"1","continuous current of the DIAZED fuse link gG":"6 A","continuous current of the C characteristic MCB":"1 A;
