ASM Sensors, Inc. Introduces WS® 31 Cable Extension Sensor Series with a New Mounting Bracket for Most Flexible Installation

Elmhurst, IL (February 16, 2009) - ASM Sensors is introducing its WS® 31 cable extension sensor series with a new mounting bracket that allows the easy and most flexible installation of the sensor and thus position measurement in almost every direction. The WS® 31 linear position sensor series offers measuring ranges of 10 and 20 inches and is well suited for many OEM production applications such as in medical testing equipment or in aerospace testing equipment.

The WS® 31 series operates on the proven and reliable cable extension position sensor principal which uses a highly flexible stainless steel cable that is drawn onto a cable drum. An internal spring maintains the tension in the cable and ensures that the cable is recoiled exactly as a single layer on the drum. The output signal is proportional to length of the cable that has been pulled out of the sensor by the moving object. The WS® 31 series is available with an analog R1K, 4-20mA or digital incremental encoder A/B/Z output.

This position sensor can be installed with many different orientations with the included mounting brackets or threaded spacer nuts. The flexible design of the sensor's housing allows the sensor to be rotated and mounted in 90 degree increments with the use of metal brackets.

With its compact size of 1.7" x 1.2" x 1.2", the WS® 31 series is an economical solution that can be easily integrated into existing systems whenever direct displacement measurement feedback is needed without requiring extensive mechanical changes in the end application.

The enclosure rating for the sensor housing is IP50 and has a linearity rating of ± 0.35% of the full scale measuring range. This sensor weighs less than 4 oz.
