Omron SHL-Q2255 Limit Switch
Omron SHL-Q2255 is a panel-mount limit switch with an 11 mm × 4.7 mm stainless sintered alloy cross roller plunger for directional machine position detection. The cross-roller actuator suits cams, slides, and moving workpieces that travel across the sensing point, while panel mounting supports compact integration through a machine surface. Its SPDT contact form provides changeover switching for general loads, and IP67 protection supports factory environments exposed to dust or moisture. The SHL-Q2255 belongs to the SHL Series within the panel-mount cross roller limit switch range from Omron industrial control products for accurate machine position, travel, and end-of-stroke detection.

The Omron SHL-Q2255 Limit Switch uses an 11 mm × 4.7 mm panel-mount cross roller plunger with a stainless sintered alloy roller for directional machine position detection. The cross-roller arrangement suits cams, slides, and moving workpieces that travel across the sensing point, while the panel-mount construction supports compact integration through a machine surface. Its SPDT contact form provides changeover switching for general loads at 50/60 Hz. IP67 protection supports industrial environments exposed to dust or moisture, and the -10 to 80°C operating range suits a broad range of automated equipment and repeated machine cycles.
The SHL-Q2255 provides at least 10 million mechanical operations and 500,000 electrical operations, supporting frequent switching over a long service life. Initial contact resistance is 15 mΩ maximum, while insulation resistance is 100 MΩ minimum at 500 VDC. The switch operates with 35 to 95% relative humidity and is specified for pollution degree 3 under EN60947-5-1. Destructive shock resistance is 1,000 m/s² and malfunction shock resistance is 300 m/s². These characteristics combine panel mounting, cross-direction roller actuation, SPDT switching, and sealed protection for accurate industrial machine position sensing.
