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. Typical applications for the My-Com high-precision switches are: • Reference point setting in X/Y tables and machine tools Introduction • 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 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 repeatability. 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. 648 www.baumerelectric.com Applications Applications Precision finishing • The My-Com is used as a control and guiding instrument for processing machines, for example as a control stop on positioning tables for drilling, milling, turning and grinding on automatic equipment. Quality control Introduction • Built into measuring and control gauges, the My-Com can indicate whether the articles concerned are within manufacturing tolerances, such as of correct thickness (double sheet control), diameter or concentricity.

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. 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. Introduction 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!
