The PRAS3 position sensor is well suited to the harsh conditions those found on off-highway construction equipment and many industrial applications.
ASM has released the PRAS3 magnetic angular position sensor in a 36mm diameter housing.
The active sensor element uses an internal, contact-free permanent magnet to determine the angular position.
The measurement ranges are available in 15 degree increments: 0-15, 0-30, 0-45 and to 0-360 degrees.
The servo flange mounting ensures quick and easy installation for the PRAS3 series.
With its IP69K stainless steel housing, the PRAS3 series is well suited to extremely harsh conditions such as those found on off-highway construction equipment and many industrial applications.
The sensor is equipped with two extra strong ball bearings to handle axial and radial loads along the sensor's 10mm shaft.
The user may choose from two types of brackets: one that is welded to the application and another that is bolted onto the application.
Three different analogue outputs are available: 0.5-4.5V, 0.5-10V and 4-20mA.
The resolution and repeatability are defined as up to +/- 0.03% over the full-scale.
The linearity is defined as +/- 0.3% over the full-scale.
All of the PRAS3 models are available with the output signal increasing either clockwise or counter-clockwise and with a housing that is rated either IP67 or IP69K.
