DescriptionThe ZPJ is a thru-bore encoder with a bore of 0. 625 inches (15. 875 mm). Additional mounting kits are available to adapt it to both standard and meteric shaft sizes. This unit is ideal for applications requiring a miniature, high precision, low cost encoder, designed with all metal construction for years of trouble-free operation.The ZPJ encoder has a flexible arm mount and blind hollow shaft. It uses two set screws that are 90 degrees apart to clamp the hub to the motor shaft. THe NPN Open Collector outputs are each current limited to 20 mA. The outputs are standard quadrature with index. The quadrature separation is typically 90 electrical degrees. Output A leads output B for clockwise rotation of the encoder shaft.SpecificationsFlexible Arm MountQuadrature OutputCurrent Sink Outputs5 Wire, 3 Foot Cable2500 Pulses Per RevolutionMax.
