Omron ZC-Q2155 Limit Switch
Omron ZC-Q2155 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, while the roller actuator provides smooth contact with cams, slides, and moving workpieces. Its SPDT contact form supports changeover switching for general loads, and IP67 protection suits industrial environments exposed to dust and moisture. Operation from -10 to 80°C and long mechanical durability support repeated use in automated machinery. The ZC-Q2155 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-Q2155 Limit Switch uses an 11 mm × 4.7 mm panel-mount roller plunger with a stainless sintered alloy roller for accurate machine position detection. The panel-mount construction supports compact mechanical integration, while the roller actuator provides smooth contact with cams, slides, and moving workpieces that pass across the sensing point. Its SPDT contact form provides changeover switching for general loads at 50/60 Hz. IP67 protection supports industrial environments where dust or moisture may be present, making the switch suitable for repeated position and travel detection on automated equipment.
The ZC-Q2155 provides at least 10 million mechanical operations and 500,000 electrical operations, supporting long service in frequently actuated machinery. Initial contact resistance is 15 mΩ maximum, while insulation resistance is 100 MΩ minimum at 500 VDC. The switch operates from -10 to 80°C with 35 to 95% relative humidity and is specified for pollution degree 3 under IEC947-5-1. Destructive shock resistance is specified at 1,000 m/s². These characteristics combine panel mounting, roller-plunger actuation, SPDT switching, and sealed protection for compact industrial position sensing. The panel-mount format is especially useful where the sensing point must be integrated through a machine surface. For another ZC-55 configuration using a sealed cross roller plunger, see the ZC-N2155 model.
