REC Manual Setting Type Optical Encoders

Nidec Components REC Manual Setting Type Optical Encoders offer a 5V_DC input voltage range, 40mA to 70mA input current range, and an IP40 protection grade. These contactless encoders can only be adjusted manually and feature a compact, lightweight design. REC series encoders come in either a click or panel seal type. The REC20, REC20C, REC20D, and RECW20D encoders have a click seal, while the RECW20D version has a panel seal. Nidec Components REC Encoders are RoHS compliant and feature a 0°C to +50°C operating temperature range.
