Angle Sensors

Novotechnik, U.S. (Southborough, MA) introduced the RSC3200 angle sensors that feature shaft connectivity options and provide absolute rotary position measurement. Analog outputs are 0.25 to 4.75V or 0.5 to 4.5V. Built-in coupling accepts D-Shaft with shaft customization available. The non-contacting sensors are fully redundant, measure angles up to 360°, and have an operating temperature range of -40 to +125 °C. Repeatability is 0.5°, resolution is 12-bit, and absolute linearity is within ±1.0% FS at 360°. For Free Info Visit http://info.hotims.com/61060-312

Linear Actuator

The Servo Cylinder from Ultra Motion (Cutchogue, NY) is a compact brushless DC linear actuator with Phase Index™ absolute position feedback. The integrated Phase Index sensor is digital, high-resolution, and non-contacting with a wide operating temperature range, and is resistant to a range of harsh environmental conditions. The combination of Phase Index with the Servo Cylinder eliminates the need for homing, limit switches, potentiometers, LVDTs, optical encoders, and Hall Effect sensors. The actuator can provide forces up to 530 lbf., speeds up to 14 in/s, and linear travel up to 7.75" with a maximum supply voltage range from 7-48 VDC.

Brushless Torque Motors

Electromate (Greenville, DE) offers QTR Series compact torque motors from Tecnotion that can be integrated directly into a machine structure, with an open inner diameter that enables wire and cable feedthrough. The motors come with completely sealed stators and integrated temperature protection and measurement sensors. The motors eliminate the need for mechanical transmission components such as gearboxes, belts, and speed reducers. They feature braided power and sensor cables with strain relief integrated in the stator housing. The motors are available with outer diameters of 105, 133, and 160 mm, and build heights ranging from 17 mm to 92 mm. For Free Info Visit http://info.hotims.com/61060-315
