Omron, A22LK Series

last update: February 18, 2015

Selector switch for secure equipment activation during maintenance

The guard lock of the operation unit prevents incorrect operation.

The key has the same shape as the following keys.
• The key of the A22TK safety key selector switch
• The trapped key of the D4JL guard lock safety-door switch
• The lockout key of the D4SL-NSK10-LK slide key unit

Features

Because the A22LK guard lock safety key selector switch uses the same key as the guard lock safety-door switch, the operator is prevented from forgetting to remove the key. the result is a safer working environment when performing maintenance.

Note: 1. Do not allow the load current to exceed the rated value.
2. The contact ON/OFF timing is not synchronized. Confirm performance before application.
3. Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The contact surfaces will become rough once they have been used and contact reliability for smaller loads may be reduced.
*1. Malfunction within 1 ms.
*2. With no icing or condensation.
*3. The degree of protection from the front of the panel.
