US Digital's New L2 Low Profile Motor Encoder

The L2 incremental encoder uses US Digital's proven EM1 optical encoder module and disk, which has billions of device-hours of dependable service in customer applications. This product continues US Digital's strong reputation for reliable, field-tested encoders. The L2 is US Digital's lowest height encoder that uses the EM1 module. It has a 0.75 in. bolt-spacing mount. The maximum resolution is 1250 CPR (5000 PPR with quadrature). The L2 comes with a single-ended output. Another benefit of the L2 incremental encoder is its fast installation. The cover snaps onto the base to secure the module. It is designed for use with a high-retention connector or cable (sold separately). Like all US Digital products, the L2 is designed and manufactured in Vancouver, Washington, USA. It is backed by prompt access to our technical and customer service teams with same-day shipping on most orders.

US Digital's E4T Miniature Optical Encoder Kit is now available with Higher Resolution!

Submitted on: 11/14/18, 11:12 AM

The E4T miniature transmissive optical encoder is designed to provide digital quadrature encoder feedback for high volume, limited space applications. It offers higher maximum speed and increased output drive than previous models. The E4T utilizes an innovative, push-on encoder disk which accepts shaft diameters of 2.0mm to .250".

Our S4T Miniature Shafted Optical Encoders are now available with Higher Resolution!

Submitted on: 11/14/18, 11:03 AM

The S4T miniature optical shaft encoder is a non-contacting rotary to digital converter. The S4T contains an LED light source, monolithic photo detector and mylar disk. The S4T encoder is available with a shaft bushing or ball bearings for motion control applications, or with shaft torque designed to feel like a potentiometer for front-panel manual interfaces. The encoder converts real-time shaft angle, speed, and direction into TTL-compatible quadrature outputs without index. It operates from a single +5VDC supply.
