Omron ZC-N2155 Limit Switch
Omron ZC-N2155 is a compact limit switch with a sealed cross roller plunger for directional machine position detection. The stainless sintered alloy roller suits targets that move across the actuator from the side, allowing smooth mechanical contact with cams, slides, and moving equipment. Its SPDT contact form supports changeover switching for general control loads, while IP67 protection supports dusty or moist industrial environments. The ZC-N2155 belongs to the ZC-55 Series within the cross roller plunger switch range from Omron machine sensing products for accurate machine travel, position, and end-of-stroke detection.

The Omron ZC-N2155 Limit Switch uses a sealed cross roller plunger with a 9.5 mm × 4.7 mm stainless sintered alloy roller for directional machine position detection. The cross roller arrangement is suited to moving targets that travel across the actuator from the side, providing smooth mechanical contact with cams, slides, and machine parts. Its SPDT contact form provides changeover switching for general control loads, while IP67 protection helps the switch withstand dust, water, and factory contaminants. The model operates at 50/60 Hz across an ambient temperature range of -10 to 80°C and supports 35 to 95% relative humidity.
The ZC-N2155 provides at least 10 million mechanical operations and 500,000 electrical operations, supporting repeated position sensing in automated machinery. Initial contact resistance is 15 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. Destructive shock resistance is specified at 1,000 m/s², while pollution degree 3 under IEC947-5-1 supports industrial installation conditions. The combination of sealed cross roller actuation, SPDT switching, IP67 protection, and long mechanical life makes the model useful where the target approaches laterally and dependable travel detection is required reliably.
