12 mm encoder adds shaft and switch options

Bourns, Inc. has expanded its Bourns® PEC11S series 12 mm surface mount incremental encoders with additional shaft lengths and SPST momentary switch options for compact control interfaces. The contacting encoder provides 2-bit quadrature output, up to 60 rpm operating speed, 3 Ω maximum closed-circuit resistance and a -40 °C to +70 °C operating range, with minimum life ratings of 15,000 rotational cycles and 20,000 switch cycles. The added mechanical options help engineers simplify panel layout, reduce redesign work and combine rotary and push input functions in one component for industrial, consumer and communications equipment.
