Note:
The outer shell of the metal receptacle used for mounting is
electrically conductive. |
Model 305 Suggested Mounting Methods |
Model 305 is typically mounted
by the knurled metal receptacle, which is press-fit into the rotating member of the machine.
When mounting horizontally, mount the Mercotac so the body of the connector rotates.

Installation Notes:
- the up arrow should not point
below horizontal
- do not solder to or bend connector
tabs
- avoid lateral forces and
mechanical loads (overly stiff or tight wires)
- do not rigid mount both ends of
connector
- limit mounting eccentricity (runout
/ wobble) to .005" (.13mm)
- provide overload protection within
the circuit
- avoid vibration and bumping
motions
