18-1842-4

Honeywell Sensing and Productivity Solutions 18-1842-4 shows up under Position, Proximity, Speed (Modules) when designers want a well-bounded, datasheet-driven building block instead of a fragile board-level workaround. Proximity sensing is validated for target material, alignment, and EMI exposure so detection margins remain stable across installation variance. In practice, they support state detection and proximity feedback so systems can enforce interlocks and closed-loop control. Engineers often balance range, hysteresis, ambient interference immunity, and mechanical integration constraints. Within robotics, repeatable position sensing improves pick-and-place accuracy under variable lighting and clutter. Across robotics, precise position sensing improves repeatability for pick-and-place tasks under variable lighting and clutter. Within industrial automation, proximity sensing confirms part presence on conveyors near oil mist and switching noise from contactors.
