Omron ZC-Q2255 Limit Switch
Omron ZC-Q2255 is a panel-mount limit switch with an 11 mm × 4.7 mm stainless sintered alloy roller plunger for accurate machine position detection. The panel-mount design supports compact installation through a machine surface, while the roller actuator provides smooth contact with cams, slides, and moving workpieces. Its SPDT contact form provides changeover switching for general control loads, and IP67 protection supports environments exposed to dust or moisture. Operation from -10 to 80°C and long service life suit repeated machine cycles. The ZC-Q2255 belongs to the ZC-55 Series within the panel-mount roller plunger switch range from Omron industrial sensing products for dependable position and travel detection.

The Omron ZC-Q2255 Limit Switch uses an 11 mm × 4.7 mm stainless sintered alloy panel-mount roller plunger for accurate machine position detection. The panel-mount construction allows the sensing point to project through a machine surface, while the roller actuator provides smooth contact with cams, slides, and moving workpieces. Its SPDT contact form provides changeover switching for general loads at 50/60 Hz. IP67 protection supports 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 ZC-Q2255 is specified for 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 IEC947-5-1. Destructive shock resistance is rated at 1,000 m/s². These characteristics combine panel mounting, roller-plunger actuation, SPDT switching, and sealed industrial protection for dependable position sensing. The panel-mount format is particularly useful when the actuator must be accessible through a machine panel or bracket. For a related ZC-55 panel-mount roller model, see the ZC-Q2155 model.
