3065 Series Limit Switch Box
The 3065 Series limit switch boxes (figure 1) mount on
either rotary or sliding-stem actuators with the
appropriate mounting kit. The switch box complies with
VDI/VDE 3845 for mounting on rotary actuators. The
mounting plate permits mounting the switch box on the
position indicator; the switch shaft couples directly to
the actuator shaft. For mounting on sliding-stem
diaphragm actuators, the switch box complies with IEC
60534–6. The switch box can also be mounted on
various Fisher Controls actuators as well as on the
Type 3710 and 3720 Series positioners.
The limit switch box is available with either inductive or
contact-closure switches. The switches can be
connected to an alarm or display device to indicate
when a pre-set limit is exceeded.

Type 3065 EI-Z—Limit switch box with cylindrical
inductive proximity switches D Easy Adjustment—Cams on Type 3065 El-S,
3065 EI-Z and 3065 EM units are self-adjusting to
indicate fully open or fully closed position when the
Type 3065 EI-S—Limit switch box with slot-shaped switch box is use on a 90_ rotation actuator. With the
inductive proximity switches Type 3065 EI-S and 3065 EM, separate cams are
used for “open” and “closed” positions so that

“SN” Series inductive proximity switches according to NAMUR in safety engineering. These switches can be used in connection with “load-side units” in safety engineering (TUEV approval)
for the construction of self-monitoring systems. These units may of course be operated with standard load-side units. In that case, however, the safety requirements would no longer be
fulfilled. The wide temperature range of these switches remains.
