US Digital EM1-2-1800-I Optical Quadrature Rotary Encoder 1800 CPR HEDS NEW
New rotary position encoder modules made by US Digital. These are drop-in replacements for the old HEDS series detectors. Made for use with 2 inch encoder disks with an index mark. Disks not included. These are new in the manufacturer's sealed trays. Check our store for lots of 10 or 50 at discounted prices. Full specifications can be found on the USDigital website.
From the manufacturer:
The EM1 is a transmissive optical encoder module designed to be an improved replacement for the HEDS-9000 series encoder module. This module is designed to detect rotary or linear position when used together with an encoder disk or linear strip. The EM1 consists of a lensed LED source and a monolithic detector IC enclosed in a small polymer package. The EM1 uses phased array detector technology to provide superior performance and greater tolerances over traditional aperture mask-type encoders.
The EM1 provides digital A & B quadrature outputs with an optional third output index channel. Each EM1 module is resolution-specific and is matched to the resolution of an encoder disk or linear strip. The EM1 module now supports all standard resolutions offered by the HEDS-9000 series encoder module and additional resolutions. The EM1 operates with a single 5V supply and provides single-ended outputs capable of sinking and sourcing 8mA. An internal 0.1 μF decoupling capacitor is designed into the EM1 to provide enhanced noise immunity over the HEDS-9000 series encoder modules
The design of the EM1 provides electrical and mechanical compatibility with HEDS-9000, HEDS-9100, HEDS-9200, HEDS-9040, and HEDS-9140 series modules.
