Overview
The Micro Switch LSYDC5KQ-FP is a factory-sealed, heavy-duty limit switch from the HDLS (Heavy-Duty Limit Switch) series, manufactured by Honeywell. This unit features a top roller plunger actuator and snap-action 1NC/1NO (1 normally closed / 1 normally open) contact configuration, making it suitable for industrial machine position detection and safety interlock applications. The integral 5-pin mini-style connector simplifies field installation and reduces termination errors.
Key Features
