Encoder Mounting Styles
NEMA 56C Face or Flange
(Solid Shaft Coupled) Requires NEMA 56C 4.5" flange adapter (flowerpot) with coupling. Can often be replaced by modular or hollow shaft encoders.
Available models: AV485, M3-1, M4-1, M485, M925
Modular Bearingless
Also known as NEMA 56C/NEMA FC Face Mounted. Requires motor stub shaft and one of the following: 115mm, 4.5", 6.75", 8.5", 12.5" C/FC Face.Avtron Encoders' Admotec KA and KX modular encoders do not require a C-Face to mount.
Available models: AV125, AV850, KA, KX, AV56, AV67, AV85, AV115, M193B, RO
Foot Mounted
The foot mounting method is usually used when encoders are coupled directly to rolls, gear boxes, or motors without C-Faces. Can often be replaced by hollow shaft encoders.
Available models: AV20, AV25, AV485, M3-2, M4-2, M485, M925
Hollow Shaft/Tethered
A stub shaft is required. Shaft requirements depend on the encoder selected. An Anti-Rotation Arm is required. Torque Arm styles are used for larger motors.
Available models: AV685, HS25A, HS35A, HS35M, M3, M4, M6, M7, M685
