PANTRONISM-1100/24VDCDIN Rail
ISM-1100
1-channel manual infrared amplifier with selectable switching and frequency modes. The ISM-1100 is a single-channel amplifier in Pantron's ISM series for long-range through-beam sensing in contamination-heavy environments. Compared with the base ISM-1000, it adds two selectable basic transmit levels, selectable light or dark switching behavior, four selectable transmit frequencies, and an alarm output for power-limit indication.
Up to 55 m range24 VDC3.5 / 3.8 / 4.0 / 4.5 kHzLight / dark selectable
Key Features
- Detection range up to 55 m in through-beam applications, depending on transmitter and receiver pairing.
- Manual operation with front potentiometer for gain setting.
- Basic transmit level is 2-fold selectable: low or high.
- Switching behavior is selectable between light and dark mode.
- Transmit frequency is 4-fold selectable: 3.5, 3.8, 4.0, or 4.5 kHz.
- Floating switching output with normally open semiconductor relay, short-circuit proof.
- Alarm output for power-limit indication and test input for system checks.
- DIN rail mounting to EN 60715.
Best Fit Applications
- Dirty through-beam sensing where frequency selection helps reduce interference from nearby optical systems.
- Industrial gates, doors, and access points exposed to rain, fog, snow, or airborne contamination.
- Bulk material, timber, paper, and processing environments where robust alignment and long range are needed.
- Installations that benefit from switchable light/dark operation without moving up to a more complex controller platform.
This page is built from the ISM-1100 catalog data on page 9 of the Pantron catalog and follows the same product-page structure used for ISM-1000.

Device Layout and Wiring Notes
- Front indicators include power (green), output status (yellow), intensity (green), and alarm (red).
- Manual gain is adjusted by the front potentiometer.
- The 4-fold DIP-switch sets basic transmit level, switching behavior, and transmit frequency.
- Wiring includes operating voltage, ground, switching output, alarm output, transmitter, receiver, and test input.
- Designed for DIN rail installation in non-safety industrial control applications.
The page 9 connection diagram shows separate terminals for switching output and alarm output, which is one of the main differences from the simpler ISM-1000 model.
