Industry’s smallest SMT encoder boosts resolution to 318 lpi
Control device brings directional sensing, TTL compatibility to space-limited applications
Currently the industry’s smallest miniature reflective incremental optical encoder, the 3 (L) x 3.28 (W) x 1.26 (H)-mm AEDR-8400-14x offers a 318-lpi resolution—improving performance over the previous 254-lpi version. The TTL-compatible encoder provides two-channel quadrature digital output for directional sensing, suiting space-limited control applications such miniature motors, digital still cameras, scanners, and printers.
The RoHS-compliant encoder integrates an LED light source and photo detector IC in a single leadless package, and use reflective technology to sense rotary or linear position. The encoder can be interfaced directly with most signal processing circuitries to provide design-in flexibility and easy integration into existing systems.
It is also insensitive to axial play and maintains performance and accuracy over a wide variation in the gap between sensor and code wheel or strip. The device can be used with a reflective code wheel to sense rotary position and velocity, or with a linear code strip to sense linear position and velocity.
Operation is from a single 2.8-V supply, and temperature range is from 20 to 85C. ($3.50 ea/50,000—available now.)
