Omron WLCA2-7-N Limit Switch
Omron WLCA2-7-N is a standard-size two-circuit limit switch with a roller lever for dependable machine position and end-of-travel detection. The lever actuator suits moving cams, slides, and mechanical targets that require repeatable switching along a defined path. Its 10 A rating supports industrial control circuits, while 15° pretravel and 70° overtravel provide practical operating movement. IP67 protection supports demanding factory environments. The WLCA2-7-N belongs to the WL Series within the standard heavy-duty roller lever switch range from Omron automation products for robust machine position sensing.

The Omron WLCA2-7-N Limit Switch is a standard-size two-circuit roller lever switch for mechanical position and end-of-travel detection in industrial machinery. The lever arrangement suits moving cams, slides, and machine parts that need repeatable switching over a defined travel path. It supports a 10 A current rating and provides 15° pretravel, 70° overtravel, and 12° differential travel. A G1/2 conduit opening supports machine wiring, while IP67 protection provides dust-tight and waterproof construction. The operating temperature range extends from -10 to 80°C for use across common factory conditions.
The WLCA2-7-N is specified for 10 million mechanical operations and 500,000 electrical operations, supporting repeated use in automation equipment. Operating force is 1040 gf and release force is 92 gf, providing defined mechanical actuation and return characteristics. The combination of standard-size construction, two-circuit switching, roller-lever actuation, high durability, and sealed protection makes the model suitable for conveyors, machine tools, transfer equipment, and other mechanisms requiring robust position feedback. Its travel characteristics also help distinguish it from WL versions with different lever geometry or operating movement. The 10 A rating supports standard industrial control switching duties. For a closely related standard-size WL roller lever switch with a different force specification, see the WLCA2-8-N model.
