H7ET-N Panel Cutout Separate mounting 40 min. 45+0.5 0 Dimensions with Flush Mounting Bracket 22.2+0.5 0 Dense mounting (48 Units - 2.5) 0 +1.0 22.2+0.5 0 Waterproofing is not possible for dense mounting * When mounting, insert the Counter into the cutout, insert the adapter from the back and push in the Counter while making the gap between the front panel and the cutout panel as small as possible. Use screws to secure the Counter. If waterproofing is desired, insert the waterproof packing. * When several Counters are installed, ensure that the ambient temperature will not exceed specifications. * The appropriate thickness of the panel is 1 to 5 mm. Note: A Compact Flush Mounting Bracket (Y92F-35) can also be used. Refer to Accessories for details. Self-powered Time Counter H7ET C-23 Counters |
