Expansion of encoder-related product lineup

In addition to “SMD-01” (miniature reflective optical encoder head) and “SM3470BB” (high-precision interpolation IC) that are receiving good reputation for their excellent performance, Seiko NPC developed and marketed “CF3412A” (transmission-type linear absolute encoder IC) and “SM3471AB” (interpolation IC). By expanding product lineup of encoder-circuit including signal processing unit, Seiko NPC contributes to customer’s requirements for encoder equipments.

img-smd01“SMD-01” Reflective linear incremental A/B-phase encoder IC

  • LED and OEIC fabricated in a miniature clear-mold package (5.3 x 4.3 x 1.7mm)
  • High precision (20μm period output signal)
  • Easy to mount (employing optical sensor array that reduces signal degradation due to variations in mounting position)

Under mass production

“CF3412A” Transmission-type linear absolute encoder IC

  • High-speed, high-precision absolute encoder head that incorporates all required functions (photodiodes for absolute/incremental encoders, preamplifier for incremental encoders, comparator for absolute encoders, serial interface) in a single chip.

Under mass production

img-sm3470b-1“SM3470BB” Interpolation IC (provides up to 32-fold interpolation, high speed/frequency)

  • Interpolation circuit of A/B/Z-phase signal, offset adjustment function and comparator built in a single chip
  • Interpolation switching function selectable from 1 to 32, from 5 to 20
  • Offset adjustment function by serial I/F
  • Operable under 125℃ which is ideal for industrial equipments

Under mass production

“SM3471AB” Interpolation IC (provides up to 16-fold interpolation)

  • Specialized for up to 16-fold interpolation by refining SM3470BB techniques
  • Low power consumption, ease of use by simplified function setup

Under mass production
