The Keyence IV4-LG5M represents a specialized infrared LED illumination unit engineered for the IV4 Series vision sensor platform. As a critical accessory in machine vision systems, this external light module enhances image acquisition quality for AI-powered inspections. The unit operates through power supplied from the connected amplifier, eliminating the need for separate power wiring. Furthermore, its IP67 protection rating ensures reliable operation in washdown and dusty environments when properly attached to compatible sensors.
The IV4-LG5M functions as an AI imaging illumination unit with a focused infrared LED light source. Specifically, this module is compatible with two sensor heads: IV4-HG500MA and IV4-G500MA. The infrared LED technology provides consistent illumination that enhances contrast for monochrome imaging applications.
Power delivery occurs directly through the connected amplifier, simplifying installation and reducing cable complexity. Consequently, the unit requires no independent power supply, which streamlines system integration in space-constrained control cabinets.
The IV4-LG5M demonstrates robust construction designed for industrial durability. The main unit case utilizes aluminum die-casting combined with PBT material, while the sensor head connector features zinc with nickel plating and PA components. Additionally, the front cover consists of acrylic material, and the cable assembly incorporates PVC, nickel plating, and TPEE for flexibility and chemical resistance.
For environmental resilience, this illumination unit achieves an IP67 protection rating when attached to applicable sensors. However, the rating excludes configurations where polarizing filters OP-88644, OP-88645, OP-88646, or OP-88647 are installed. The operating temperature range spans from 0 to +50°C with no freezing conditions. Meanwhile, relative humidity tolerance reaches 85% RH or less without condensation. Furthermore, the unit maintains ESD safety compliance with IEC61340-5-1 standards, protecting sensitive electronic components during handling and operation.
Mounting the IV4-LG5M follows the established IV4 Series installation protocols. First, verify that the target sensor head is either IV4-HG500MA or IV4-G500MA, as these represent the only compatible models. Next, attach the illumination unit to the sensor head using the appropriate mounting bracket from Keyence's accessory lineup, such as the OP-88638 2-axis adjustment bracket or OP-88911 common mounting bracket. The connection procedure requires proper alignment between the light unit connector and the sensor head interface.
Power connections require no separate supply, since the amplifier connected to the sensor delivers all necessary power. After physical attachment, verify the IP67 seal integrity by checking that all connectors are fully engaged and the front cover remains undamaged. For detailed visual guidance, Keyence provides video manuals covering wiring and installation procedures for IV4 Series components.
