System connection
Readhead only (no interface)
The ATOM readhead is available in several variants:
• Cable variant with a 15-way D-type connector
• Cable variant with interboard connector
• FPC variant
None of these readhead variants has an integral calibration (CAL) button. Provision
should be made in the customers’ electronics for momentarily connecting the CAL line
to 0V to initiate the calibration routine, switch AGC on /off or restore factory defaults.
See page 54 for pin-out information.
Calibration is an essential part of system set-up that optimises the incremental signals
and phases the reference mark. See page 45 for information on the calibration routine.

For cable variant with interboard connector
Ensure that the interboard connector is inserted into the connector on the customers’ electronics.
NOTE: Care should be taken to ensure correct orientation
• Use a metal clamp around the cable ferrule to ground the readhead cable and ensure continuity of the shields
• Provide appropriate strain relief
• Ensure suitable clamping to retain interboard connector to the mating connector
