Switch mounting arrangement MKK/MKR-040-NN-2

Switch mounting arrangement with magnetic field sensor and mounting duct

The switch activator is a magnet that is built into the carriage (no switching cam necessary). The switch activation points can be positioned anywhere along the stroke.

Version: Hall sensor (PNP NC) or reed sensor (change-over contact)

Notes for mounting:

The magnetic field sensors are pushed into the top T-slot in the cable duct and fixed with set screws. The cables are routed along the side of the T-slot for switches.

Switch mounting with magnetic field sensor, connector and sensor mount

Sensor mounting kit

The switch activator is a magnet that is integrated in the carriage (no switching angle needed). The switching positions can be freely configured via the stroke.

General mounting instructions:

The sensor mounting is only permitted on one side of the linear module (right or left) and is only done after the linear module has been attached to the mounting base. For a description of the mounting and determination of the switching positions, see the instruction manual for the linear modules. See "Accessories" section for technical data

Socket and plug, cable duct

Attach the socket to the side with the most switches. The socket and plug are not pre-wired. The variable sliding attachment allows switching positions to be optimized during start-up. The plug can be mounted in three directions.

Cable duct

The cable duct is fastened in the T-slots on the side of the frame. Fastening screws widen the profile and ensure that the cable duct is securely mounted.

See the illustration for the position of the slot.

The cable duct will accommodate up to two cables for mechanical switches and three cables for proximity switches.

Fastening screws and cable grommets are included.

Mounting examples of switches

Determination of the switching position

Switching distance: The switching distance is the distance between the carriage center (TM) and the zero point (0) when a switch is actuated (indicated in mm). Example of a mechanical limit switch (assuming the zero point is at L/2):

Maximum switching distance = 0.5 x (max. travel distance) – excess travel = 0.5 x effective stroke

For safe operation of the linear module the excess travel must be greater than the braking path.

For MKR... and MLR...: The acceleration travel sa can be assumed as the reference value for the braking distance.

For MKK...: In most cases, the following is sufficient as a guideline value for the excess travel (braking path): Excess travel = 2 x screw lead P.

Note the smallest possible switching distance (determined by attachments):

mechanical-mechanical = 60 mm; mechanical-proximity = 45 mm; proximity-proximity = 28 mm.

for MKR-145: mechanical-mechanical = 62 mm; mechanical-proximity = 49 mm; proximity-proximity = 35 mm

The switches as well as socket with plug are fixed in the upper T-slots of the frame and actuated by a switch tab on the carriage.

2)	right (R)
3)	Direction of travel
4)	0.5 x stroke
5)	Excess travel
6)	0.5 x max. travel path
