OMRON D4F dimension

last update: November 06, 2012

Roller lever (Metal lever, resin roller)
D4F-[]20-[]R

Roller plunger (Metal roller)
D4F-[]02-[]R

Roller lever (Metal lever, resin roller)
D4F-[]20-[]D

Roller plunger (Metal roller)
D4F-[]02-[]D

Note: Each dimension has a tolerance of 0.4 mm unless otherwise specified.

Slow-action (1NC/1NO), (2NC), (2NC/2NO), and (4NC)

Note: Variation occurs in the simultaneity of contact opening/closing operations of 2NC, 2NC/2NO, and 4NC contacts.
          Check contact operation.
*1. The OF value is the maximum load that opens an NC contact (11-12, 21-22, 31-32, 41-42).
*2. The RF value is the minimum load that closes an NC contact (11-12, 21-22, 31-32, 41-42).
*3. The PT2 and TT values are reference values.
*4. The D4F is used in accordance with EN81 and EN115 at a minimum DOT of 30° and 2.8 mm.

Note: 1. The above values are initial values.
           2. Once the contact is opened or closed with an ordinary load, it cannot be used for a load smaller than that. The
               contact surface may be rough, which impairs the reliability of contacting.
*1. The degree of protection shown above is based on the test method specified in EN60947-5-1. Be sure to confirm in
       advance the sealing performance under the actual operating environment and conditions.
*2. Durability values are calculated at an operating temperature of 5 to 35°C, and an operating humidity of 40% to 70%.
       Contact your OMRON sales representative for more detailed information on other operating environments.
*3. Do not apply 1 A at 125 VAC to more than two circuits.
*4. The value will vary depending on factors such as the switching frequency, the ambient environment, and the reliability
       level.
       Be sure to confirm correct operation with the actual load before application.
*5. The contact resistance was measured with 0.1 A at 5 to 8 VDC with a fall-of-potential method.
