Limit/Home Sensor Mounting Procedure
Tools Required For Adjustment:
Allen Key, Phillips Head
Travel Limit Sensors signal the motor to stop whenever the table carriage is approaching the end of
travel. These sensors can be adjusted over the table travel. The home sensor provides a fixed
reference point which the carriage can be commanded to return repeatedly.
Identify Limit Sensors and mounting hardware per the configuration, which is appropriate to the application.

Attach limit/home sensor trigger flag to the side of the carriage using button head cap screws. The trigger-
mounting holes are located on either side of the table for flexibility.
Mount sensor bracket to the top t-slot of the base extrusion. The bracket assembly should be loosely
mounted together when received. To install, loosen the socket head cap screw (do not remove) until the
bracket clip can be rotated into the t-slot and the bracket sits flush to the extrusion. Tighten screws.
Orient wire on switch to desired direction and mount switch to sensor bracket by tightening the Phillips head
screw.
Standard switch settings to utilize full table travel are 89mm (404XR) or 135mm (406XR) from centerline of
switch target to the endblock. See sketch below.
Switches are adjustable by loosening the screws and sliding the assembly along the extrusion.
6) Refer to Wire Color Code.
NOTE: When adjusting Sensor Pack switches, the screws may be turned a
maximum of 1/4 turn. Any further loosening may result in the nut becoming
disengaged. If this occurs the sensor pack will need to be disassembled so that
the nut can be reattached.
