Connector Location and Pinout

M12 Connector

An eight pin, A-coded, male M12 connector is used on these DC60 units. It is located on the back or side of
the unit. This connector is the Turck eurofast FS 8 or equivalent. The pinout for the connector is shown
below.

inputs and the analog output signal.
Pin 3: Preset to Zero Input:
resistor. A high-to-low transition on this pin will preset the analog output to its minimum value. (In the case
of a 4 to 20 mA output, the output becomes 4 mA. In the case of a 0 to 10 Vdc Output, the output becomes 0
Vdc.) Therefore, this pin must be pulsed to ground (Pins 2 or 8) to preset the position. This input is heavily
filtered to prevent an accidental preset during normal operation, so the minimum pulse duration is 2,000 mil-
liseconds.
All DC60 encoders use a nonvolatile memory technology known as F-RAM. Unlike older
memory technologies such as EEPROM, F-RAM does not have a limit on the number of times
the memory can be written to. You can preset the position as often as necessary in your appli-
cation.
Pins 4 and 6: No Function:
used, these pins should be tied to DC Return (pins 2 and 8) for normal operation to prevent them from picking
up any electrical noise in the environment.

put. The default is CW increasing output when looking at the shaft. If you are fabricating a custom cable and
want CW increasing output, this pin can be left open or attached to +DC Power Input (pin 1). Connecting this
pin to DC Return (pins 2 or 8), forces the output to increase with CCW rotation. If using a molded cordset,
connect the wire on this pin to either +DC Input Power or DC Return for normal operation. Do not leave the
wire floating.
