1INTRODUCTION
The 2620 Sensor Interface unit permits
convenient connection of all kinds of sensor types
to die protection logic units such as OmniLink
MPC controls, System 2600 die protection units,
or even third party units. Sensors and probes
installed in or near the die are connected to the
Sensor Interface which also provides sensor
power
.
The Sensor Interface is designed to be located
near the die to facilitate die changes, setup, and
troubleshooting. It permits quick connection of
individual sensors via industry standard M12 4
pin connectors (also known as Micro-DC or
Eurofast connectors) or of all sensors at once via
an optional Quick Connect Receptacle (Link or
customer supplied).
1.1 Features
•Solid state sensors (NPN or PNP), spring probes, and mechanical sensors may be used as inputs to
the Sensor Interface.
•Up to 8 sensors can be powered and passed through to a die protection unit via the internal
connectors (usually through a Link or customer supplied bulk quick connection).
•6 M12 4 pin sensor connectors (also known as Micro-DC or Eurofast connectors) are provided on
the face of the unit for connecting individual sensors to channels 1 - 6.
•3 Banana plug/binding post connectors are provided on the face of the unit for connecting grounding
spring probes or mechanical sensors to channels 1 - 3.
•No configuration is necessary to select sensor type. This Sensor Interface is designed for die
protections units that can select NPN or PNP sensors on their own and so passes the sensor signal
directly through.
•The Sensor Interface is powered from 115 to 230 VAC and provides 24 VDC @ 0.5 Amp total for
powering sensors. Sensor power is available on each of the front panel M12 connectors, the optional
bulkhead connector, and internal terminal strips.
•In cases where 0.5 Amps is not enough power, the Sensor Interface can be powered by an external
24VDC power supply up to 10 amps.
•The enclosure of the Sensor Interface features a removable bulkhead that can be fitted with a quick
connection receptacle so that only one cable must be plugged in from the die. Link has an optional
standard connector (a 19 pin Turck receptacle suitable for up to 16 channels) or, if desired, a
customer supplied connector can be used.

2INSTALLATION
The dimensions and mounting footprint of the Sensor Interface are shown below in Figure 2. When
mounted to the press frame or other high shock areas, Link highly recommends using the included
shock mounts, which will add about 0.75 inches (19mm) to the depth of the unit.

2.1 Wiring
In the following sections, refer to Figure 3below for the locations of particular connectors and other
relevant features.
2.1.1 Power Wiring
WARNING:
National Codes and standards (NEC, VDE, BSI, etc.) and local codes
outline provisions for safely installing electrical equipment.
Installation must comply with specifications regarding wire types,
conductor sizes, branch circuit protection, and disconnect devices.
Failure to do so may result in personal injury and/or equipment
damage.
The Sensor Interface is typically powered by 115VAC, but can be powered from 100 to 240 VAC OR
can pass through an external 24 VDC supply at up to 10 Amps. An external +24 VDC power supply
might be used in cases where unusually high power draw sensors require more than the 0.5 Amps of
current that is available from the internal power supply of the Sensor Interface. Pull power wires with
the appropriate color code in conduit between the Sensor Interface enclosure and the source of power.
Knockouts are provided at the bottom of the enclosure for this purpose.

When using AC power, use the L1, L2 and PE
terminals. When using an external +24 VDC power
supply, use the +24, GND, and PE terminals. The
table at right shows the usage and specifications of
the connections on the power connector.
WARNING:
The Sensor Interface can be powered from EITHER 100-240VAC OR
+24VDC. Never hook up both AC and DC power at the same time.
When using an external +24 VDC supply, make sure the Power
Jumper (see Figure 3) is removed so that the internal +24 VDC supply
is disconnected.
2.1.2 Internal Sensor Connector Wiring
The Internal Sensor Connector (see Figure
3) is primarily used in conjunction with a
Quick Connect bulkhead connector for
mass die termination or if there are some
sensors that are always present on the
machine regardless of what die is
installed. Link offers (Link PN 109090)
an optional quick connect bulkhead
connector (using a Turck CS-19
connector) that is prewired and ready to
plug into the Internal Sensor Connector.
Figure 4 at right shows how a typical
sensor is wired into this connector. The
unit is supplied with a blank plate for
mounting an existing connector if a
connector system is already in use.

Figure 4: Typical Wiring to Internal Sensor Connector
NOTE: If a Quick Connect bulk
connector is wired into this
connector but there are
inputs that are not actually
connected in the die, then
the corresponding front
panel connectors are still
available for use.

Doc #: L-2600-1020 Page 8 Rev. 01
2.1.3 Front Panel Sensor Connectors
There are 6 M12 4-pin connectors on the front of Sensor
Interface that allow individual sensor to be conveniently
plugged in. These are wired to match the typical industry
standard 2 or 3 wire DC sensors with molded M12
connectors. M12 connectors are also available (Link PN
108046) that can be wired in the field. Figure 5 at right
shows the pinout and typical connection for the M12
connector.
There are also 3 Banana Plug/Binding Post connectors on the
front of the Sensor Interface that are intended for use with
single wire grounding sensors such as Whisker Probes,
Spring Probes, or other mechanical sensors that are
grounding in nature. Note that Pin 2 on the first 4 of the M12
connectors (labeled WP for “Whisker Probe”) is also a
grounding-only input so that such sensors can be tied in that
way as well. For these sensors, it may be necessary to source
more current through the sensor than is required with solid
state sensors in order to maintain good electrical contact. The grounding inputs have extra pull-ups for
this purpose and even more current can be supplied by switching on the corresponding dip switch for
that channel on the door board of the unit (see “Whisker Probe Switches” in Figure 3).
2.1.4 Wiring to the Die Protection Unit
Figure 6 at right shows a close-up of the outputs connector
that must be wired to the Die Protection Unit. Depending on
the number of channels your Die Protection Unit can handle,
it may not be necessary to use all the outputs. Always
connect the ground (“GND” in the figure at right) on the
outputs connector to ground on the Die Protection Unit.
Then O1 through O8 (or however many are needed) can be
connected to the corresponding Die Protection Unit input.
