The EN Series of two-bit gray-code incremental encoders come housed in 11, 12 and 16-mm packages. The EN Series of two-bit gray-code incremental encoders come housed in 11, 12 and 16-mm packages. The EN11 generates 20 pulse/rev, features top and side-adjust encoders with metal shaft and bushing, threaded and plain bushings, and optional push-on switch and detents. EN12 and EN16 create 24 and 12 or 24 pulses/rev, respectively. The encoders are dustproof and have a rotational life of 30,000 cycles. They operate in temperatures from –30 to 85°C.
