The E2 optical encoder is designed as a direct replacement for the Avago HEDS / HEDM 5500 - 5600 series. The E2 is a rotary encoder with a molded PBT enclosure, which utilizes either a 5-pin locking or standard connector. The E2 is easy to add to existing applications and only consists of four main components; base, cover, hub/encoder disk and optical encoder module. The E2 is normally designed for applications of 10 feet or less. For longer cable lengths, adding a PC4 / PC5 differential line driver is recommended. The base and cover are both constructed of rugged 20% glass filled PBT. Attachment of the base to a surface may be accomplished by utilizing one of several machine screw bolt circle options. Positioning of the base to the centerline of a shaft is ensured by the use of our centering tool. The cover is securely attached to the base with two 4-40 panhead screws to provide a resilient package protecting the internal components. The internal components consist of a mylar disk mounted to a precision machined aluminum hub and an encoder module. The module consists of a highly collimated solid state light source and monolithic phased array sensor, which together provide a system extremely tolerant to mechanical misalignments. Connection to the E2 product is made through either a 5-pin locking or standard connector (sold separately). The mating connectors are available from US Digital with several cable options and lengths.
