Low light alarm

The high power of the PX allows it to operate reliably for extended periods with significant buildup on its lens. At some point, however, the head may need to be cleaned. The low light alarm lets you decide when the light level becomes dangerously low, so you can schedule cleaning at an appropriate time.

Alarm in real time for disconnection or output breakage

Output 2 always performs the opposite action of output 1. It can detect disconnection or output breakage with logic.

Saving customised settings

Minimize downtime due to unauthorised changes

Often when attempting, to troubleshoot a sensor, users may change settings that shouldn't be changed. Simplify the troubleshooting process by reverting back to your SAVED settings.

Interference prevention up to 4 units

Several sensors can be closely positioned without interference.

The PX Series communicates through an optical link on the side of the amplifier, ensuring that only one sensor emits light at a given time.

Automatic Sensitivity Tracking

With conventional sensors, once the set point is adjusted, it's just a matter of time before debris leads to false outputs, and it has to be "tweaked' or reset. With the DSC function (Dynamic Stability Control), the PX continuously and automatically adjusts the set point according to the environmental conditions. Allowing your line to run longer between cleanings. Combine the powerful beam with DSC and the Low Light Alarm, and you may never have to take a sensor troubleshooting call in the middle of the night ever again.

Edge Triggering

Without DSC, debris will eventually cause the light throughput to fall below your set point. Edge triggering can be used to ignore slow, gradual decreases in intensity due to buildup, and only focus on a quick change in conditions as would happen when a target is present. Using the Edge Triggering mode with one of the 5 timer options below improves flexibility in your application.

5 Timer functions

Equipped with 5 timer functions.

• ON-Delay
• OFF-Delay
• One-shot
• ON-Delay with OFF-Delay
• ON-Delay with One-shot
Timer duration selectable (1ms to 9999ms)

Customize the PX display

The PX display can be set for:

• Standard Display
• Peak / Bottom display
• Bar Graph / Excess Gain
• Hi-resolution, extended display (up to 65504)
• Current modes (Light-on/Dark-on, Power Mode)

Attenuate the signal

For applications where the transmit/receive distance is short, the amplifier may saturate at [9999]. This may make it difficult to detect smaller or translucent targets. The attenuation feature can drop the light intensity below the saturation point, and allow stable detection.

Invert the PX display

The digital display can be inverted if needed to align it with other devices on a DIN rail

Power saving function

This mode automatically turns off the digital display. It can also reduce current consumption during operation.
In ECO mode: 820 mW

Simple setting by external input or button operation

Simple TEACH, SHIFT or SCALE via front panel, or remote input*

Simple setting by external input or button operation

% Tuning

If light intensity fluctuates due to dust or misalignment, you can periodically adjust the setpoint with the touch of a button, or pulse from an external input.* The PX set value is adjusted to a fixed percentage of the current value. You can adjust the percentage between 0 to 99% (typical for diffuse heads), or 0 to -99% (typical for thrubeam heads).

Zero shift function

This function adjusts the current received light intensity. When using a reflective type, you can forcibly set the received light intensity of the background to 0. This is effective when there is little difference in light intensity between the background and a target.

Display scaling function

You can freely set the displayed light intensity with this function. When using several units, you can standardise the received light intensity.

Emission stop input

LED transmission can be individually stopped by external input
