ID1102G Dual Channel Gearwheel Encoder Kit Product data Features • • • • • • Highly miniaturized gear 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 Speed and position control in high-speed spindles Industrial / laboratory / office automation Milling, grinding and cutting spindles Rotating equipment High-speed motion control Mechatronics applications 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 ID1102G incremental encoder kit consists of an encoder and a gearwheel (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 gearwheel is in ferromagnetic steel and has a module 0.5. 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 user-programmable or can be programmed ex-factory. The resolution depends on a filter setting that limits the maximum speed of the encoder vs. the gearwheel. The resolution also depends on the maximum distance between the encoder and the gear. The resolution and maximum speed for a certain maximum air-gap are selected in Tables 2 and 3. Gearwheels Gearwheels should be made of ferromagnetic steel and have a module 0.5. Gearwheels with 12 up to 120 teeth are available and can be selected in Table 5. 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.
