ID1102L Dual Channel Linear Encoder Kit Product data Features • • • • • • Highly miniaturized linear 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 Linear actuators Industrial / laboratory / office automation X-Y stages Pick & Place assembly 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. Holder type A is for evaluation purposes only. 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 ID1102L incremental encoder kit consists of an encoder and a linear scale (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 linear scale 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 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 scale. The resolution also depends on the maximum distance between the encoder and the scale. The resolution and maximum speed for a certain maximum air-gap are selected in Tables 2 and 3. Scales Scales with different lengths (Fig. 4) are selected in Table 5. Each scale has a backside adhesive layer and may be mounted on any substrate, using a 0.1 – 0.2 mm high alignment edge for correct positioning in front of the encoder. Alignment edge Scale Metallic or non-metallic substrate 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.

Dimensions (mm) of ID1102 encoder on encoder-holder type B. The “Encoder center” must be centered with respect to the width of the linear scale (Fig. 4). Scales TPLS04-026 (top and middle) and TPLS05-205 (bottom). All dimensions in mm. Period-length is 1.28 mm. Both scales have backside adhesive. Scale thickness includes adhesive, but not the release liner. The special periods at the left and right ends of the scale are intended for another encoder and should not be used with the ID1102L.
