PANTRONISM-1000/24VDCDIN Rail

ISM-1000

1-channel manual infrared amplifier for harsh industrial environments. The ISM-1000 is the base single-channel amplifier in Pantron's high-performance light barrier family. It is built for long-range through-beam detection in harsh environments and uses manual transmit-power adjustment, light switching behavior, a short-circuit-proof floating switching output, and a test input for system checks.

Key Features

Detection range up to 55 m in through-beam use, depending on transmitter / receiver pair.
Manual operation with potentiometer-based gain setting.
Switching behavior fixed to light mode.
Floating switching output using a normally open semiconductor relay.
Test input for system check and validation.
DIN rail mounting to EN 60715.

Best Fit Applications

Bulk material level sensing in dirty or dusty process areas.
Industrial gate and door monitoring in rain, fog, or snow.
Elevator door and access control.
Timber, paper, food, and washdown environments where conventional photoelectric sensors struggle.

Pantron's high-performance light barrier platform is positioned for extreme dirt resistance and long range, with through-beam, retro-reflective, and diffuse mounting concepts available across the family.
