ELESA original design
Digital position indicators EN 954 have a direct coupled drive with digital indications. The two housing component parts are ultrasonically welded, thus making the housing is especially sturdy and compact.
The foam rubber seal at the back of the indicator housing prevents the transmission of vibration between the machine and the counter mechanism and also acts as a seal.
Special attention was paid to the positioning of the readout window. The numbers are easily legible and are even enlarged by the magnifying effect of the sight glass.

Before installation of the position indicator, a bore hole for the torque limiting contact point is to be drilled, as shown in the in the adjacent drawing. With the Mounting Adaptors EN 952.1 the hollow shaft (with bore 14 H7) of the position indicator can be adapted to fit the spindle. If a reduction in the diameter of the hollow shaft is to be made at the same time as mounting a control knob, Control Knobs GN 957 are available which combine both functions in a single component (no adaptor bushings required). The position indicator is mounted with the torque limiting contact point inserted in the bore hole, to stabilize the housing in place. The hollow shaft is mounted to the spindle and secured with the set screw. With Clamping Plates GN 954.7 spindles can be clamped and secured after adjusting. |

|
The digital position indicator is equipped with a hollow shaft that is slid directly onto the spindle and is connected to the spindle by a set screw. The spindle rotations are transmitted to a counter directly by a gearbox. For torque support, a pin of the housing projects into a hole made on the machine side, establishing the position relative to the mounting site. |

|
The transmission ratio and counting direction of the counter are determined by the pitch of the adjusting spindle. The indicated value after one turn starting from the 0 position serves as a characteristic value. Decimal places are indicated in red. |
