Its spring-actuated lock (closed-circuit principle) applies 1300 N holding force to the separate actuator — enough to keep a heavy access gate closed against machine vibration or an operator leaning on it. The lock includes an auxiliary release for emergency override. ## Washdown-rated enclosure and wiring Rated IP66/IP67, the plastic housing survives hose-down cleaning in food or beverage lines. Three M20 cable entries give flexibility for gland placement. Screw terminals accept 1x (0.5…1.5 mm²) or 2x (0.5…0.75 mm²) solid conductors — typical for 14–18 AWG control wiring. The 10 A thermal current rating covers most 24 VDC or 120 VAC safety circuits; at 24 V the contacts are rated 3 A.","metaTitle":"Siemens 3SE5322-0SD21 Safety Limit Switch","metaDescription":"Siemens SIRIUS 3SE5322-0SD21 mechanical safety switch with spring-actuated lock, 1300 N holding force, IP66/IP67, slow-action positive opening contacts.","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":"3SE5322-0SD21","description":"Safety position switch with tumbler Locking force 1300 N 5 directions of approaches Spring-locked Auxiliary release on front Magnet voltage 24 V DC Monitoring actuator 2 NC/1 NO Monitoring magnet 2 NC/1 NO Supplied without actuator. please order separately","Locking Force":"1 300 N","During Storage":"-40 ... +80 °C","Repeat Accuracy":"0.05 mm","Thermal Current":"10 A","lifecycle_stage":"current","Cable Entry Type":"3x (M20 x 1.5)","During Operation":"-25 ... +60 °C","Fastening Method":"screw fixing","Shock Resistance":"30g / 11 ms","Circuit Principle":"slow-action contacts","Mounting Position":"any","Product Brand Name":"SIRIUS","Degree Of Pollution":"class 3","Product Designation":"Mechanical safety switches","Width Of The Sensor":"54 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":"185 mm","Vibration Resistance":"0.35 mm / 5g","at 120 V rated value":"6 A","at 125 V rated value":"0.55 A","at 240 V rated value":"3 A","at 250 V rated value":"0.27 A","Design Of The Housing":"special design","Design Of The Product":"with separate actuator and with tumbler","at AWG cables stranded":"1x (20 ... 16), 2x (20 ... 18)","Design Of The Interface":"without","Locking Mechanism Design":"spring-actuated lock (closed-circuit principle) with auxiliary release","Material Of The Enclosure":"plastic","according to EN ISO 14119":"1 000 N","according to IEC 60068-2-6":"0.35 mm/5g","according to IEC 60068-2-27":"30g / 11 ms","Substance Prohibitance (Date)":"10/01/2011","Supply Voltage Of Magnet Coil":"24 V","Type Of Electrical Connection":"screw-type terminals","Insulation Voltage Rated Value":"250 V","Design Of The Actuating Element":"5 directions of approach","Design Of The Switching Function":"positive opening","Number Of Directions Of Actuation":"5","Product Function Positive Opening":"Yes","Suitability For Use Safety Switch":"Yes","Consumed Active Power Of Magnet Coil":"3.5 W","Surge Voltage Resistance Rated Value":"4 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)","Design Of The Housing According To Standard":"No","Number Of Switching Contacts Safety-Related":"4","Material Of The Enclosure Of The Switch Head":"plastic","continuous current of the DIAZED fuse link gG":"6 A; for a short-circuit current smaller than 400 A","continuous current of the C characteristic MCB":"1 A; for a short-circuit current smaller than 400 A","continuous current of the quick DIAZED fuse link":"10 A; for a short-circuit current smaller than 400 A","Mechanical Service Life (Operating Cycles) Typical":"1 000 000","Minimum Actuating Force In Directions Of Actuation":"30 N","Design Of The Interface For Safety-Related Communication":"without"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$335.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/1ec4d98f2b0cbfa53b5ee8b470092060.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=195330&mlfb=3SE5322-0SD21"},"ai":{"faq":[{"question":"Does 3SE5322-0SD21 include an actuator?","answer":"Yes.
