BEI Kimco Expands VCA Developer’s Kit
Vista, CA — BEI Kimco recently improved its voice coil actuator (VCA) developer’s kit to include three new actuator sizes with greater force and stroke capabilities. The new sizes offer a greater diversity of actu- ators for off-the-shelf selection. The new additions round out
the kit selection to a total of six actu- ators with force performances now ranging from as low as 15.56 N to as high as 1,512 N, and total strokes ranging from 6.35 to 31.7 mm (0.25 to 1.25 in.). Outside actuator diame- ters range from an extremely com- pact 32 mm size to 113.8 mm (1.26 to 4.48 in.) for a wide selection of sizes. The original developer’s kit was
designed to make building proto- types easier for people unfamiliar with VCA technology. The complete “solution-in-a-box” bypasses the learning curve by providing all nec- essary components to get an actua- tion system up and running. Instead of having to figure out which con- troller and software to specify to put together a working system, the VCA novice can simply purchase the kit with the desired size and perform- ance and have everything needed to build a prototype easily. Uses range from actuation, position, force control, proof-of-con-
cept, full-function prototypes, test bed for actuator system design, standalone use for single purpose actuation, live testing, vibration gen- erator, bio tissue fatigue testing, and student engineering projects. The kit is available in six config- urations, each with a different VCA

paired with an appropriate PCB con- troller. A built-in feedback sensor and programmable controller with Motion - Lab software runs on the user’s local PC. The controller incorporates an I/O board that allows physical inputs and outputs, which include pushbuttons (digital inputs), LEDs (digital out- puts), and potentiometers (analog input). Sample programs for flow, motion, oscillation, timers, and memo-
ry are included. Contact: BEI Kimco, 1499

Tessenderio, Belgium — Melexis, a global microelectronics engineering company, continues to make ad - vances in tire pressure monitoring system (TPMS) technology with the introduction of its 3rd generation TPMS IC — the MLX91804. According to the company, the
Melexis Releases Smallest Lowest-Power Sensor IC
chip has a 60 percent smaller foot- print and draws 3 times lower sleep mode current than any competing TPMS IC on the market. It is sup- plied in a robust 14-pin DFN type lead-less package. It incorporates a sophisticated microcontroller and MEMS-based pressure sensing ele- ment, as well as energy efficient 315/433 MHz wireless transmitter (supporting data rates up to 150 kbit/s) and 125 kHz receiver for com- munication with the vehicle’s rele- vant electronic control unit (ECU). A 16 kB embedded program memory is included for the storing of custom application data and libraries. In addition, there is a built-in single- or dual-axis high-g range accelerometer to support all market available wheel
sensor auto-location functionalities. Together with high-g range and
fast data acquisition accelerometer, it also represents a step closer to the tire mounted sensor (TMS) implementa-

Camarillo, CA — Micronor, a manu- facturer of fiber optic kinetic sensors for both industrial and medical use, has introduced a fiber optic micro - switch. According to the company, it is the world’s first device of its kind and has been created to meet the challenging requirements of MRI, medical and industrial applications. Engineers will appreciate the prod- uct’s interchangeability with the industry-standard V15 series electri- cal microswitch. The Micronor MR386 is de -
signed to outperform conventional electrical microswitches and limit switches. The entirely non-electrical, passive sensor provides EMI and RFI immunity, isolation from high volt- age and lightning, inherent safety in explosive atmospheres, and can oper- ate interference-free over long dis-
tances — up to 1,500m (4,921 ft). Contact: Micronor, Inc., 900
