PANTRONIMX-A840DIN Rail / Panel

IMX-A840

The IMX-A840 is an 8-channel automatic multiplex amplifier for large multi-beam installations in harsh industrial environments. It combines automatic transmit power adjustment, selectable switching behaviour, switching delay, primary/secondary operation, sensor control, and alarm output on a high-density channel platform.

Key Features

Detection range up to 55 m in through-beam use.
Automatic transmit power adjustment for changing process conditions.
Switching behaviour light / dark programmable or selectable by channel.
Adjustable switching delay from 0 to 7 seconds.
Alarm output and sensor control support deeper system integration.
Primary/Secondary operation for expanded multi-channel systems.

Best Fit Applications

Large multi-beam sensing arrays in dirty, wet, or contamination-heavy applications.
Advanced multiplex detection where automatic compensation reduces maintenance burden.
OEM systems requiring alarm signalling and sensor control on an 8-channel platform.
Installations where long range and adaptive operation are critical.

Pantron's IMX platform is designed for long-range infrared detection in demanding industrial environments where conventional photoelectric sensing can struggle with contamination, distance, or multi-channel coordination.

Device Layout and Wiring Notes

Front indicators show channel status, secondary display, and operation mode display, with test and reset controls on the housing.
Function selection is handled by three DIP-switch groups on the side of the housing, allowing per-channel configuration.
The catalog notes that the switch number corresponds to the matching transmit channel when setting functions by channel.
This page covers the model-specific output and basic transmit configuration while keeping the shared automatic 8-channel platform structure.
