Encoder

Same Sky has created an absolute encoder family for motor shafts from 9 to 15.875mm (5/8inch). Called AMT25 and said to be accurate to ±0.2°, the family relies on the same in-house capacitive ASIC for sensing as all of its AMT series encoders, which is claimed to resist environmental particulates. Outputs options are 12 or 14bit, both over a bi-directional ...

EBE Sensors+Motion has revised its manual handwheel rotary encoder, designed for precise adjustment of machines. Inside the encoder, called HR100, the 100 detent ‘clicks’ are created by magnetic rather than mechanical means, and position sensing is via Hall magnetic detection rather than physical contacts. Output is the traditional A-B two-phase quadrature waveform, created by a circuit with new Hall sensors ...

CUI Devices has announced an incremental encoder for motors with shafts between 1 and 6.35mm in diameter. “The AMT12 series brings the same durability, accuracy and immunity to environmental particulates as current AMT encoder models in a more compact 22.2 x 22.2 x 12.8mm package,” according to the company. Outputs are single-ended cmos quadrature A and B signals that can ...

Nanotec has introduced UL/CSA certified 56mm flange (NEMA23) stepper motors with integrated position encoders. There are four ASA5618 motors, giving options on 140 or 230Nm torgue (which corresponds to 88 or 109.5mm length) and either a incremental (4,096 CPR / 16,384 PPR) or multi-turn (16bit multi-turn, 17bit single-turn) encoder. Current per winding is 4.2A and ingress protection is to IP65. They are ...

Adafruit has made an I2C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style), allowing the user to pick devices with the appropriate step-count per revolution, with or without a push switch. “The [pre-soldered] on-board microcontroller is programmed with ...

Oriental Motor of Japan is offering stepper motors with battery-free multi-turn absolute position encoding that can ride through power-loss. The encoder, dubbed ‘mechanical absolute encoder’, combines mechanical gearing and magnetic sensing to provide unambiguous position feedback to the motor controller up to 1,800 revolutions, and so is suited to absolute position indication in machines with long leads-crews and high-ratio gear ...

Microchip has introduced a touch controller family for ‘knob-on-display’ (KoD) human-machine interfaces. These interfaces add a physical ‘clicky’ knob to the front of a display without traditional rotary encoder electronics. Instead, a passive rotatable clicky knob is simply stuck to the front of the display glass (diagram right) and one or more electrodes underneath interact with the display’s existing capacitive ...

Advanced Micro Peripherals has released a stand-alone, low latency H.264 video streamer with four NTSC/PAL/RS-170 composite sources. Called XStream-SD4, “this ruggedized SWaP-optimised solution is tailor-made for even the harshest military and industrial applications”, according to company founder and CEO Lee Foss. On-board is a dedicated hardware compression engine capable of encoding all four video channels at full size and full ...

Elma's E18 rotary encoder comes in through-hole and surface-mount versions in the 14.4 x 11.4 x 6.5mm body size.

Electromechanical component distributor, Foremost Electronics, has added switching products from Elma Electronics to its linecard. These include the X4 and  MR50 rotary switches. The former is a designed for the toughest requirements, says the company, and has an optional pushbutton function. The switch incorporates a magnetic, Hall effect (contactless) sensing system for rugged, reliable, long life operation. The microcontroller-based circuitry ...
