May 16, 2008
The robust design includes a double ball bearing shaft support with a variety of stainless steel shaft options, plus a mounting flange, lever arm and other drive accessories.
Variohm Eurosensor has released heavy-duty rotary potentiometers from Novotechnik for precision angle measurement in extreme environmental conditions.
With a choice of IP67 or IP69K protection ratings, the durable IPX series is available in single or true redundancy output versions.
The compact range has a hermetically sealed housing in anodised aluminium or stainless steel with dimensions of 79mm in diameter and 35mm in length.
The robust design includes a double ball bearing shaft support with a variety of stainless steel shaft options, plus a mounting flange, lever arm and other drive accessories.
Electrical connection for each sensor channel is via an M12 threaded connector for IP67-rated use or with sealed PG style cable glands for IP69K protection applications.
The range is based on the Novotechnik conductive plastic element and multifinger wiper technology that offers more than 100 million cycles of lifetime and a positional repeatability to within 0.002% of the electrical range.
In addition, excellent shock (to 50G) and vibration (to 5G at 2kHz) resistance is available as standard.
The IPX range was originally designed as a custom unit for demanding electro-hydraulic steering angle measurement applications in agricultural machinery where high levels of vibration and shock loading and exposure to high-pressure spray are frequently encountered.
It is now used in chemical processing, cranes and off-road transportation.
