Measuring 0.93 in. high x 2.00 in. dia, complete operational unit includes integral dual ABEC 5 ball bearing and stainless steel spring mount that provides 30° rotational adjustment. Options include 4-8 pole 3-phase commutation signals for brushless motors, 5-26 Vdc input voltage, and resolutions from 500-5,000 ppr derived directly from encoder disc.
Original Press Release:
QD200 Hollow Bore Encoder
With Bores sizes up to 0.625" the QPhase(TM) QD200 has been designed to eliminate the assembly hassle and hidden cost of installing modular or kit encoders onto OEM products. The QD200 is a complete operational unit with an integral dual ABEC 5, ball bearing, insert molded hollow shaft support that provides the mechanical stability for this low profile (0.93" high by 2.00" diameter) high resolution encoder package. Using our proprietary sensing technology we are able to obtain an incremental, 5000 PPR, plus Index pulse, without the use of interpolation schemes. The stainless steel flexible spring mount provides for 30° rotational adjustment to permit precise commutation alignment and has been designed to allow for more motor tail shaft run out than typical modular or kit type units can tolerate. Product options include: 120° C continuous ambient operating temperature, 4 to 8 pole three phase commutation signals for brushless motors, 5-26 VDC operating input voltages, high voltage line driver outputs on both incremental and commutation lines and standard resolutions from 500 PPR to 5000 PPR derived directly from the encoder disc.
