The standard My-Com range of the most diverse mechanical and electric types largely reflects the requirements of the market. With its extremely compact design, the My-Com can also be easily integrated in very constrained surroundings. ® ® ® Precision finishing Referencing 8 XY-tables on machine tools μ 0,001 mm repeat accuracy Ensured reliable repeat accuracy of one micrometer makes My-Com the most precise limit switch in the world. The mechanical device – with a service life of 10 million switching operations – provides ultra-precise reference signals for most diverse applications ® 1 μm accuracy even in harsh environments My-Com precision switches retain their ultimate precision even under most adverse conditions. Viton and silicone gaskets prevent the gold-plated contacts from impairment by dirt, dust and condensation and thus ensure constant micrometer switching precision throughout the entire service life. ® Typical applications for the My-Com high-precision switches are: Reference point setting in X/Y tables and machine tools Monitoring of the closing and locking accuracy of injection molding dies Detection of the smallest deflections, movements and deformations Integration in measuring sensors, gauges and activating pins Calibration of measuring instruments in quality control Monitoring of surface roughness Other applications in precision mechanical engineering ® Housing fronts and product variants My-Com high-precision switches excel by ultra-compact design merged with big product variety. - Conical and tapered housing fronts - Activating force configurable from 30 cN tp 250 cN according to application - Spherical hard metal or ruby tips for lateral approach ® Rigorous attention was paid to the design of the My-Com precision switch to reduce the number of components to an absolute minimum. Just three moving parts and high-quality materials guarantee a large number of switching operations with constant repeat accuracy. Short, linear displacements in just two directions and low activating forces further increase the reliability and service life of the My-Com precision switch. The My-Com has proven its impressive reliability in over 1 million applications. ® ® Quality control Laboratory test setups Concentricity Referencing Checking Home check in measuring gauge parts for correct thickness Monitoring concentricity - Integrated amplifier with LED for 50 mA load current (PLC) ® mirrors and beam-splitters position sensor Precision referencing 9 Technical specifications Mechanical data Repeat accuracy (T = const) Mechanical lifetime Switching frequency Max. activating velocity Temperature range Standard cable material Protection class (standard) < 0,001 mm (1 micron) 10'000'000 switchings 0 - 10 Hz < 30 mm/s -20 °C to +75 °C (-5 °F to +165 °F) PVC IP 50 LED indicator The My-Com types with transistor output are available with LED output indicators. Transistor output The My-Com types L, G and M are available with a transistorized output. When supplied with this configuration, the output circuit is supplied normally open (NO). A protective diode is incorporated into the circuit to protect against transients. Activation force For most My-Coms, the appropriate activation force can be defined at the time of ordering. Technical specifications Increased environmental protection (IP 67) For applications in harsh environments (dust, oil, cooling fluid) we recommend the waterproof My-Com D, H or M. The My-Com type L, with transistor output, is also available with the same protection (IP 67). The sealing membrane for all of these is made of Viton. Maximum installation torque (not lubricated) If the published installation torque specifications prove to be insufficient for your application, we recommend using a nut locking liquid to secure the My-Com. The published specifications for maximum torque must not be exceeded!
