Omron SHL-D55-01 Limit Switch
Omron SHL-D55-01 is a compact limit switch with a stainless steel plunger for direct position detection in low-current industrial control circuits. The straight actuator suits machine stops, slides, fixtures, and moving parts that approach the switch head-on, while the SPDT contact form provides changeover switching. Its microload configuration makes it suitable for signal-level position feedback, and IP67 protection supports factory environments exposed to dust or moisture. The SHL-D55-01 belongs to the SHL Series within the microload plunger limit switch range from Omron industrial switching products for precise machine position and end-point detection.

The Omron SHL-D55-01 Limit Switch uses a 7.8 mm stainless steel plunger for direct mechanical position detection in microload control circuits. The straight plunger actuator suits machine parts that approach the sensing point head-on, making it useful for compact stops, slides, jigs, and automated mechanisms. Its SPDT contact form provides changeover switching, while the microload configuration is intended for low-level control signals rather than higher-current general loads. IP67 protection helps shield the switch from dust, water, and factory contaminants. The operating temperature range extends from -10 to 80°C, with 35 to 95% relative humidity for industrial environments.
The SHL-D55-01 provides at least 10 million mechanical operations and 500,000 electrical operations, supporting repeated actuation in automated equipment. Initial contact resistance is 15 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. The switch withstands destructive shock of 1,000 m/s² and malfunction shock of 300 m/s². These characteristics combine compact plunger actuation, microload switching, long service life, and sealed construction for dependable position or end-point detection where small electrical signals are used. The model is particularly relevant when the application needs direct plunger contact with low-level switching.
