Reliably detects the position of registration marks on various webs of material running at very high speed for applications in the printing, packaging and converting industries. The switching frequency of the sensor is 50Khz with a repetability of 5µs. This provides unprecedented stability of the mark position. It is ideal in processes where timing is critical.

The sensor uses a 2.2mm white light spot to detect a mark, product edge, or product feature as it approaches the sensor in any direction. Vertical and horizontal line versions us a tri-color emitter to enhance performance. 5µs repeatability provides high accuracy at high speed. The only question is... "How fast can the machine run?"

When using our conversion brackets, the sensor is a drop-in replacement for existing registration mark sensors. The conversion bracket provides the user with a hole-for-hole bolt pattern of the removed sensor and when installed aligns the focal point in the exact same position as the removed sensor eliminating the need for any modification.

AGS™ AUTOMATIC GAIN SELECT
This unique feature provides automatic digital selection of amplifier gain based upon your sensing requirements.

AUTOSET ADJUSTMENT
The AUTOSET adjustment routine only requires the push of one button, one time. There are four AUTOSET Modes to choose from: Light State, Dark State, Two-Point, and Dynamic. Light State AUTOSET is used when there is a light background with a dark mark; Dark State AUTOSET is used when there is a dark background with a light mark; Two-Point AUTOSET is used when the background and mark are very similar in color or contrast; Dynamic AUTOSET is used when there is a requirement to jog the mark past the sensor on-the-fly, or when there isn't an opportunity to stop the system for setup.

CONTRAST INDICATOR™
Provides “at-a-glance” performance data.

REMOTE AUTOSET
Remotely AUTOSET the sensor by applying a contact closure from the Remote AUTOSET input wire to negative (0VDC) or positive (10-30VDC), depending on model, as shown in the wiring diagram. The Remote AUTOSET command will duplicate the last manual AUTOSET performed.

EDR° (Patent No. 5,621,205)
Another unique feature is the digitally controlled EDR (Enhanced Dynamic Range) circuit. It prevents Dark State saturation and expands the operating range without reducing amplifier gain.

TIMER
When the “OFF” delay pulse stretcher is enabled, the output duration is extended by 10 milliseconds. Enabling the Timer allows ample time for the controller to respond. The time durations of the gap between marks must be longer than the selected delay.

HIGH SPEED
10µs response time when responding to Light or Dark State.
5µs repeatability.
H & V Models:
12µs Response Time
6µs Repeatability

CONNECTIONS
Built-In 6 inch (152mm) pigtail with 5-pin connector (accessory cable required) or 6 foot (1.8m) cable.

MOUNTING OPTIONS
Through-hole or Bracket Mount.

REMOTE PROGRAMMING (XM/XMC-1 Models Only)
Remotely program the sensor's four AUTOSET Modes, Change the Timer, Invert the output, make minor adjustments, and repeat the last AUTOSET performed by applying a contact closure to negative (0VDC) in a simple sequence of pulses. This can be accomplished using a PLC pulse train, an HMI, or a momentary pushbutton switch.

Features

NOTE: H & V models use tri-color LEDs, and are only available with Two-Point and Dynamic AUTOSET modes.

Special Features

X-MARK HMI REMOTE PROGRAMMING
The Remote Programming feature of the X-MARK^™ allows the customer to configure, AUTOSET, and tweak the sensor using a PLC pulse-train, HMI, NPN transistor output, or momentary pushbutton switch to 0VDC/ground. This provides the customer with control over every aspect of the sensor configuration without having to physically touch the sensor. If you have several sensors on your machine; have sensors buried deep within the mechanical structure of the machine; or have your sensors in safe areas behind interlocks… you can easily access these sensors remotely to perform a "digital changeover" due to this unique, special feature.

Detailed Features

SELECT AUTOSET MODE:</br />While holding down the AUTOSET button, tap the "SELECT" button to advance through the four AUTOSET Modes. The direction of the LED's indicates the current AUTOSET mode illustrated below. When desired AUTOSET mode is selected, release the AUTOSET button (see below for details).

Detailed Features

INITIATE AUTOSET: First, select the appropriate AUTOSET Mode.

A. LIGHT STATE AUTOSET MODE - Place the light background in view, press and release the AUTOSET button (Note: Not available on H & V models).

B. DARK STATE AUTOSET MODE - Place the dark background in view, press and release the AUTOSET button (Note: Not available on H & V models).

C. TWO-POINT (Span Adjustment) - Place the background in view, press and release the AUTOSET button. Then place the mark in view, press and release the AUTOSET button.

D. DYNAMIC - With the background in view, press and hold the AUTOSET button, move the mark in view, or past the sensor, then release the AUTOSET button.

INVERT: To invert the output, press and hold the INVERT button for 2 seconds.

TIMER: To select the 10ms pulse stretcher, press and hold both buttons for 2 seconds.

REMOTE AUTOSET:
1. When using the Remote AUTOSET line, the AUTOSET mode must first be selected manually via the pushbuttons, see Select AUTOSET Mode.
2. To initiate a Remote AUTOSET, pulse the AUTOSET line using the same sequence as specified in the pushbutton instructions for that AUTOSET mode. The pulse must have a minimum duration of .75 seconds and is active low for XM/XMC-1 and -2 models and active high for XM/XMC-3 models. See Connections and Dimensions.

NOTE: AUTOSET automatically selects Output “ON” for mark. LT/DK line on XM/XMC-2 and -3 models will override automatic output selection.
