gamma V / gamma V-P

Vacuum- / Pressure Switch electronic -1...0 bar / -1...+10 bar

These electronic vacuum and pressure switches are trendsetting in view of technology and design. The series „gamma“ is designed as acost-saving electronic switch for all applications where little weight and a slim body is helpful. Short response time and easy handling are further arguments for usage in all kind of handling and many other industrial automation systems. The switchpoint, switching hysteresis and the switching logic can be adjusted easily by means of an implemented self-learning function (teach function). The sensor generates high-precision signals which are processed by an integrated circuit and transformed to an open collector output signal and / or to an analog signal. Alternatively a cost-efficient version with potentiometer instead of the teach function is also available. The sensor can be ordered with Gthread, NPT-thread or flange-adapter.

  • Compact and robust design
  • Leightweight
  • Transistor output signal / analog signal
  • Self-adjusting with teach function
  • LED-switching indication
  • Switching logic programmable
  • Screw thread or flange connection
