Overview Industry/Application Specifications Related Info  

Overview / Design Principle:

It is an industry-standard Size 14 (1.44" diameter), servo or face-mount encoder unit with a rugged, metal housing. The Series E14 includes precision bearings, an O-ring seal, and a choice of 1/4" or 1/8" diameter stainless steel shaft. Series E14 incorporates the latest in microelectronic packaging, LED light sources, and matched sensors. The incremental encoders outputs are designed to be compatible with most 5V TTL circuits with options for higher voltage 12 and 15 VDC. Shielded cable is standard. Line drivers with complementary outputs are available for longer cable runs and/or higher ambient electrical noise immunity.
