ability. Can be used with both standard loads and micro-

loads.

• Free of lead, cadmium, and hexavalent chrome, reducing the

burden on the environment.

• Conforms to EN115 and EN81-1.

Be sure to read the “Safety Precautions” on page G-277.

Furthermore, secure the Switch with screws or equivalent parts that are tightened in a single direction so that the Switch cannot be easily removed.

Doing so may cause damage or deformation of the case. • Use crimp terminals not more than 0.5 mm in thickness. Otherwise, they will interfere with other components inside the case. The crimp terminals shown below are not more than 0.5 mm thick. Manufacture Type J.S.T. Wire size FV0.5-3.7 (F type) AWG20 (0.5 mm2) V0.5-3.

Date of Production Termination Production of the D4D-R Series will be terminated in March 2006. Product Replacement 1. Dimensions The D4D-R and D4N-R use the same mounting method, and mounting hole. The multi-contact structure and the extra 4 mm in length, however, are different. 2.

F502-EN2-04.book Seite 281 Dienstag, 26. Juli 2005 5:48 17 List of Recommended Substitute Products : The actuator on the D4D-R is a non-safety type. The D4N-R is recommended for safety applications (form lock type). Be sure to mount it correctly. Using M screws is recommended to comply with European standards. Therefore, the M20 conduit model is recommended for use in new designs.
