D4B-@N
Dimensions and Operating Characteristics (Unit: mm)
Note: Omitted dimensions are the same as those for the Roller Lever Type Models
D4B-2@@@N have a G1/2 conduit opening.
D4B-4@@@N have a M20 conduit opening.
Switches
Note: Unless otherwise specified, a tolerance of ±0.4 mm applies to all dimensions.
*1. The lever can be set to any desired position by turning the operating position indicator.
*2. In terms of construction, the Switch is a General-purpose Limit Switch rather than a Safety Limit Switch.
Note: Variation occurs in the simultaneity of contact opening/closing operations of 2NC contacts. Check contact operation.
*1. The operating characteristics of these Switches were measured with the roller level set at 31.5 mm.
*2. The operating characteristics of these Switches were measured with the rod level set at 140 mm.
*3. Only for slow-action models.
*4. Only for snap-action models.
*5. Reference values.
*6. Must be provided to ensure safe operation.
