Switch Location
The L2-L9 limit sensors are fixed at the end of travel locations. The H2-H9 home
sensors are fixed at the center of travel.
Sensor Pack Switch
Location
The L11-L14, H11-H14 Limit/Home options are enclosed in a sensor pack that is
bolted to the side of the table. These sensors are adjustable along the length of
the sensor pack. (Wire terminates in a 5-pin connector; extension cable included)
N.O./N.C. Options
Normally Open (N.O.) switches are typically used as home sensors and are
typically located between the limit sensors. Normally Closed (N.C.) switches are
generally used as defense circuits to prevent damage to components caused by
over-travel.
Sinking/Sourcing
Options
Sinking Switches (a.k.a. NPN): The output lead of this switch provides an electrical
path to ground when activated. Sourcing Switches (a.k.a. PNP): The output lead of
this switch provides a positive (+) voltage potential relative to ground. Note: refer to
the controller’s manual for input compatibility.
