A bilateral (double-ended) input shaft is standard; single-end configuration available on request.<\/p>\n<\/details>\n<details style=\"border:1px solid #D8DCE3;border-radius:6px;margin-bottom:10px;padding:3%;\">\n<summary style=\"font-weight:bold;color:#1B3F6E;font-size:clamp(14px,2vw,17px);cursor:pointer;\">What encoder types can be mounted on the NRV-E030 tail shaft?<\/summary>\n<p style=\"color:#3A3A3A;font-size:clamp(13px,1.8vw,16px);line-height:1.7;margin-top:10px;\">Any standard keyed rotary encoder with the matching bore diameter can be mounted on the NRV-E030 tail shaft: incremental (5V&ndash;24V, 100&ndash;10,000 PPR), SSI absolute, or resolver-type.

The NRV-E030 is the ideal solution for chain-driven systems requiring closed-loop speed feedback.
