Linear Motion Position Sensor Features Extremely Low Profile

Sept. 30, 2008
The highly miniaturized 9600 Linear Motion Position Sensor Series from BEI Duncan Electronics, a company of Custom Sensors & Technology (CST), Inc., features a short 0.15" (3.8mm) mounting terminal, and provides an extremely low profile. The overall height of the sensor is 0.50" (12.7mm), which allows installation in applications with abnormally tight packaging constraints such as joystick controls, HVAC, robotics, medical, aerospace, and industrial automation and controls. Offering superior precision feedback, the low profile potentiometer features a spring return shaft that follows the surface of the measured assembly. This simplifies the mechanical interface needs of the installation. The 9600 Series is constructed of high-temperature (135°C) plastic materials to provide a highly ruggedized electromechanical device for reliable position feedback in most applications, from delicate laboratory to harsh environments. The 9600 line of sensors complements the company’s other product configurations with the longer terminal lengths of .280" (7.1mm). The 9600 Series is compatible with industry-standard terminations for virtual plug-and-play installation. Innovative packaging designs are also available to provide cost-effective, reliable solutions for any application requirement. Performance of the 9600 miniature sensor series is accurate over a temperature range of -40°C to 135°C, shock up to 50 G's, vibration of 15G's, 50 to 10,000 Hz, and humidity level of 95 percent at 38°C. Other features include standard electrical travel (stroke) lengths of 0.5" (12.7mm), 1.0" (25.4mm) and 1.5"(38.1mm) for measurement versatility. Standard linearity is ±2 percent with ±0.35 percent, the best practical linearity based on stroke length. Mechanical life is rated at two million full cycles and five million dither cycles. Miniaturized injection-molded bodies measure 0.35"W (9mm) by 0.50"H (12.7mm) with lengths of 1.06" (26.98mm), 1.56"(39.6mm) and 2.06" (52.3mm), depending on electrical travel. Pricing is from $12.00 each in production quantities. • Total Electrical Trave (A) inches mm – 1.50(38.1) • Total DC Resistance – 5.1K • Linerity Over Active Electrical Travel - +/-2% • Power Rating At 70°C, Watts - .75 • Temperature Limits- -40°C to +135°C
