Rotary Position Sensors Live Long In Critical Applications

The PHS family of rotary position sensors enable precision sensing in harsh environments and in critical applications. The family consists of three separate series: PHS04, PHS07, and PHS11.  They convert angular mechanical position or the motion of a shaft or axle to an analog or digital electrical signal and are designed for applications that require adjustments to control variable outputs such as position, speed, or volume. Shared characteristics include dust-proof construction.  The PHS11 components offer a rotational angle of 360° and operating temperature ranges from -40°C to +120°C. All PHS rotational sensors can be hand or wave soldered and feature lifespans of greater than a million cycles, or at least 300,000 in the case of the PHS04 with a 500,000 cycles option available.  They measure 2.2-mm high and the PHS04 measures 4 mm x 5 mm.
