Quick commissioning and easy configuration Switching speed as permanent factory default for mechanical and electronic speed switches, PC configuration software for digital speed switches, direction-related switching points as an option Maximum system uptime and unrivalled durability under the harshest conditions Proven HeavyDuty design, bearings at both shaft ends, HeavyDuty connection technology and ultra-robust sensing technology Reliable in any environment Extremely resilient and thick-walled housing, outstanding corrosion resistance, sealing concept with long-term stability Reliably protected against bearing damage. Encoder shaft with bearings at both ends (where feasible by design), generously sized bearings in large distance to each other, high reserve capacity to endure strong radial/axial shaft loads, hybrid bearings with ceramics balls to discharge inductive shaft current Applications HeavyDuty speed switches from Baumer have been setting the standards for robustness, reliable function and variety of the range for years. They often fulfill the decisive safety function by triggering a switching output when the switching speeds are exceeded or fallen below. In the case of a mechanical centrifugal force switch, the centrifugal force of the centrifugal force at the limit speed moves in a radial direction and actuates the change-over switch. For electronic and digital speed switches, speed-dependent electrical signals are generated and correspondingly internally evaluated for the actuation of up to three switching outputs. HeavyDuty speed switches and speed monitors support functional safety implementation, for example at Drives Steelworks and rolling mills Cranes and hoists Oil and gas Mining Wind turbines Theater technology Centrifuges Transport and handling systems Automated guided vehicles Dosing and filling stations Cutting installations, punches and presses High-frequency spindles Pharmaceutical installations Saws and any other application where operators are in the danger zone. Technology Hübner Berlin – the original from Baumer Hübner Berlin, now Baumer Hübner, is the Baumer competence center for HeavyDuty sensors for drive technology. The brand Hübner Berlin represents the global standards for reliable encoders, tacho generators and speed switchtes in proven HeavyDuty technology. More than 60 years of expertise and experience as global market leader merge with cutting-edge technologies in unmatched robust and durable products. Proven HeavyDuty principle The extremely resilient housings are key for the unrivalled service life and reliability of the Baumer HeavyDuty encoders. These robust housings with solid and thick walls are the perfect protection against outside impacts. The torsion-resistant design is intended to endure high loads by shock and vibration. Functional safety with certified safety components SIL / PL certified sensors, encoders and signal evaluation units used as safety components in the sense of the machine directive 2006/42/EG simplify system safety evaluation and functional safety implementation in the application. Safety evaluation and safety certification of a complete system according to e.g. EN ISO 134849 is mandatory to be carried out by a notified body. Durable double-sided bearing setup Thanks to unmatched resistance to axial and radial load, the Baumer concept of bearings at both shaft ends is well proven and tried and tested for decades in electrical machinery engineering. Baumer HeavyDuty encoders feature - wherever mechanically feasible - bearings at both encoder shaft ends for unrivalled long service life and maximum mechanical reserve capacity. Outstanding, sea water resistant corrosion protection Baumer HeavyDuty rotary encoders are ideally suited for corrosive environments thanks to optimized material selection and highly resistant coatings for successful long-term use, for example near shore and offshore. Their corrosion protection corresponds to categories C4 or CX (C5-M) in accordance with the standard EN ISO 12944. Special equipment options for operation in the arctic, tropics and desert are available on request. Reliable protection against shaft currents Particularly in the case of rotary encoders on frequency converter-controlled electric motors, current overshoots in the ball bearing of the rotary encoder may occur. The lubricant can burn locally and the lubricant effect can be impaired. Electrically insulated bearings provide a remedy for this failure. Some hollow shaft designs come with isolated or hybrid ball bearings to compensate shaft currents. Additional slip ring earthing (optional) can be used for capacitive shaft current discharge. Solid shaft encoder designs provide spring washer couplings with isolated hub as protection against shaft currents. Best electromagnetic compatibility Baumer encoders with proven HeavyDuty technology by Hübner Berlin come in interference-resistant design which has been optimized according to latest EMC knowledge. All products are tested upon burst reistance, at high-voltage up to 4 kV. Large variety of HeavyDuty combinations In HeavyDuty product combinations, HeavyDuty encoders, tacho generators and speed switches build one single and robust unit. This way, besides the speed information other signals are available for control evaluation for multiple application tasks in drive technology. HeavyDuty product combinations deliver various output signals using one single shaft. They offer significant space-saving capabilities and ensure maximum durability and service life.
