IRVINE,
Calif., – Duncan
Electronics, a division of BEI Technologies, Inc., has
developed a new compact optical incremental encoder based
on their reliable Opto-ASIC technology. The new device
features an integral 5 pin mating connector that mates
with both AMPHENOL and MOLEX standard configurations. This
combination allows designers greater flexibility in integrating
a very high resolution, complete encoder solution into
an extremely small package, ready for "plug 'n play" installation.
 The
920 Series offers one of the industry’s smallest
optical disc-reading caliper configurations, capable of
accepting disc radii as small as 9.78mm with resolutions
up to 2450 PPR (Pulses Per Revolution). This Opto-ASIC
technology allows the unit to be very tolerant to mounting
alignment issues, enabling them to be installed without
tight tolerance constraints. This is important when considering
the added costs of time-consuming alignment issues during
assembly.
Phased-Array
Opto-ASIC Technology Advantages
The combined advantages of highly miniaturized packaging and the success of Duncan's
Opto-ASIC design, a phased array photo diode IC noted for its high tolerance
to axial movement (+/- 0.010") and low power consumption (50mA max.), the 920
offers a leveraged value in its use in a myriad of new and emerging applications,
including security systems, meter control and automation applications. This range
of Opto-ASIC chips offers 5-volt TTL-compatible dual channel quadrature output
with index options.
New Integrated
Connector, Reduced Footprint
Designed to further reduce assembly time and lower interfacing costs, the 920
Series is featured with an integral 5-pin connector that mates with industry
standard AMPHENOL and MOLEX connector configurations. The unit's overall footprint
is only 1.25" x 1.05" x 0.39" (31.75mm x 26.67 x 9.9mm), including caliper, connector
and PCB mounting board. The 920 can be specified for SMT or conventional fastener
mounted installations.
Standard stainless steel code disks are available in a broad range of standard
radii, with standard resolutions starting at 90 PPR (0.365"/9.78mm radii) and
ranging up to 2540 PPR (requiring a .920"/23.37mm optical radius). This family
of disks can also accommodate shaft diameters from 0.125" to 1.0". Not all resolutions
are available in each diameter. BEI Duncan Electronics also offers a lower cost
photographic film code disk capable of operation at 105 C and resolutions up
to 2540 PPR.
"This new generation encoder offers high performance with very small space needs,
where to the design engineer these attributes are rarely this compatible" stated
John Pindroh, BEI Duncan Sales Manager. He further stated, "The joint efforts
between core customers and our engineering group enabled us to balance these
constraints, resulting in greater product flexibility and lower unit pricing."
