Precision mechanical switches My-Com® by Baumer

Micrometer precision: 70 times more accurate than a hair is thick! Repeat accuracy of 1 micrometer –

Friday, 26. March 2010

With a repeat accuracy of 1 micrometer, Baumer’s My-Com precision switch is the most precise mechanical limit switch.

  • Extra robust probe tips
  • Protection class IP 67
  • Operating temperature from -20 to +75

The robust probe tips made of high-performance ceramic, stainless steel or spherically ground ruby enable the My-Com to operate reliably even under harsh conditions with consistent repeat accuracy. For applications in moist or heavily dusty environment the precision switch is available with protection class IP 67. Its operating temperature ranges from -20 to +75 °C. The field of application s for mechanical limit switches is very broad. Due to the versatile features as well as its compact housing designs (M8 x 0.5), the My-Com is very interesting for machine tool building or manufacturers of automatic assembly and handling machines. The precision switch is also used to gauge various measuring equipment or for calibration and quality control during the production process.
The ingenuity of the product that at the same time guarantees a high number of switching cycles is the simplicity of the construction of the switch. Only three moving parts as well as high-quality materials ensure the repeat accuracy of +/- 0.001 mm and that an activating force of only 30 cN is sufficient to operate a My-Com.

Aerospace & Defense – R25 Heavy Duty Brushless Resolvers

topban-aerospaceAerospace & Defense

When the military relies on a line of resolvers for proven performance, you know it’s a top-of-the-line product. Precise feedback and speed control of their aircraft at all times is imperative to pilots. That’s why they trust Harowe brand resolvers to deliver reliable and accurate feedback.
Thrust reversers, throttle valve indicators and starter/generator feedback are just some of the critical mechanical and jet operation applications that Harowe brand resolvers control. They are also used for flap position indicators, fuel control valve indicators, inertial guidance systems and auto-pilot controls. Battling gravity and top speeds, pilots must be confident their resolvers will perform to specification.
aboutus-adHarowe products are designed to meet aerospace and defense requirements, including: high-speed applications (over 30,000RPM), high-temperature environments (up to 200C), high-shock and vibration environments, dual speeds, and tandems for redundancy applications. We can supply COTS, Modified COTS and ITAR solutions.
