ID1102C Dual Channel Rotary Encoder Kit Product data Features • • • • • • Highly miniaturized encoder Differential inductive sensing principle Insensitive to magnetic interference fields Robust against oil, water, dust, particles Programmable resolution and maximum speed Optional with cable, connector and holder Brushed and brushless motors Industrial and laboratory automation Rotary stages Robotics, assembly equipment High-speed motion control Encoder holders Different encoder holder options are available and can be selected in Table 6. The encoder holder type A (Fig. 5) may be mounted on any substrate using 4 screw-holes. It has a strain relief for the cable. The encoder holder type B (Fig. 3) may be mounted on any substrate. Use half-holes on encoder PCB housing and alignment pins for accurate positioning. Description The ID1101C incremental encoder kit consists of an encoder and a codewheel (Fig. 1). The encoder is an integrated circuit in a PCB housing. It provides incremental A and B output signals in quadrature (Fig. 2). The codewheel is a PCB with passive copper strips. The orientation of the encoder is selected in Table 1. Resolution, maximum speed and airgap The resolution and the maximum speed of the encoder are programmed ex-factory. The resolution depends on a filter setting that limits the maximum speed of the encoder vs. the codewheel. The resolution also depends on the maximum distance between the encoder and the codewheel. The resolution and maximum speed for a certain maximum airgap are selected in Tables 2 and 3. Codewheel The codewheels are shown in Fig. 4 and are selected in Table 5. The codewheel may be mounted on a hub, using a rim for accurate positioning in front of the encoder. The encoder without holder may be mounted on nonmetallic substrates. Use half-holes on encoder housing and alignment pins for accurate positioning. Encoder cable and connector The encoder can be supplied with a flat cable of pitch 1.27 mm and a connector (Fig. 6). The cable length and the connector type are selected in Tables 7 and 8. Encoder programming The Evaluation and Programming Tool (EPT) including an interface board and the ASSIST software is available for the linearization and programming of the encoder. 3D models of encoder, holders and scales STEP models available on www.posic.com.
