Omron SHL-Q2155 Limit Switch
Omron SHL-Q2155 is a panel-mount limit switch with a stainless sintered alloy cross roller plunger for directional position detection. The cross-roller actuator suits cams, slides, and machine parts that travel across the sensing point, while panel mounting supports compact mechanical integration. Its SPDT contact form provides changeover switching for general loads, and IP67 protection supports demanding factory environments. The SHL-Q2155 belongs to the SHL Series within the panel-mount cross roller switch range from Omron machine control products for reliable machine position, travel, and end-of-stroke detection.

The Omron SHL-Q2155 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 is suited to cams, slides, and moving workpieces that pass across the actuator from the side, providing smooth mechanical contact during repeated operation. Its SPDT contact form supports changeover switching for general loads at 50/60 Hz. IP67 protection helps the switch operate around dust, water, and common factory contaminants, while the operating temperature range of -10 to 80°C supports demanding industrial environments.
The SHL-Q2155 provides at least 10 million mechanical operations and 500,000 electrical operations, supporting frequent switching in automated equipment. Initial contact resistance is 15 mΩ maximum, while insulation resistance is 100 MΩ minimum at 500 VDC. The model is specified for pollution degree 3 under EN60947-5-1 and withstands destructive shock up to 1,000 m/s² and malfunction shock up to 300 m/s². These characteristics make it suitable where panel mounting, cross-direction roller actuation, SPDT switching, and sealed industrial protection are required together. Panel mounting and the cross roller are key physical selection differences within the SHL range. For another SHL Series cross-roller configuration in the supplied product range, see the SHL-Q2255 model.
