Structure and Nomenclature Structure Movable Plunger Rubber Cap (NBR) * Rubber cap provides a tight seal and ensures a long service life and smooth reset at low temperatures. Seal Packing (NBR) * Seal packing withstands a pressure of 186 kPa. Terminal Protection Cover * D4E-@N has a wide wiring space of 10 mm horizontally. Bearing * The bearing load strength has been increased to prevent faulty resetting of the bearing, which may occur when the roller is pressed with excessive force. Built-in Switch * Switch cover ensures high insulation between the terminals and die-cast. Double insulation means that grounding is unnecessary. Meets UL, CSA, and EN standards. * Prevents the movable piece from being pushed in too far, and thereby contributes to a longer service life. Die-cast Case * Zinc die-cast case is anti-corrosive and tough. Wiring Ease * Wired made easier using (D4CC-type) plug-in connector. Screw Terminal * Screw terminal incorporates a M3 screw with a toothed washer. 3 D4E-@N Contact Form Screw Terminal Type Plunger Connector Type For AC For DC Lever NC (COM) 1 (COM) 1 2 (NC) 4 (NO) Positioning piece * NC 2 (NC) 4 (NO) * The position of the positioning Positioning piece is not always the same.

Precautions for Correct Use Operating Environment * Seal material may deteriorate if a Switch is used outdoor or where subject to special cutting oils, solvents, or chemicals. Always appraise performance under actual application conditions and set suitable maintenance and replacement periods. * Install Switches where they will not be directly subject to cutting chips, dust, or dirt. The Actuator and Switch must also be protected from the accumulation of cutting chips or sludge. Not Suitable Suitable * Be sure to connect a fuse with a breaking current 1.5 to 2 times the rated current to the Limit Switch in series in order to protect the Limit Switch from damage due to short-circuiting. When using the Limit under the EN ratings, use a gI or gG 10-A fuse that conforms to IEC60269. Mounting * Secure the Switch with two M4 screws and washers. The tightening torque applied to each terminal must be 1.18 to 1.37 N*m. Tighten the screws to the specified torque. An excessive tightening torque may damage the Switch and cause a malfunction. Mounting Holes Two, 4.3 dia. or M4 hole * Constantly subjecting a Switch to vibration or shock can result in wear, which can lead to contact interference with contacts, operation failure, reduced durability, and other problems. Excessive vibration or shock can lead to false contact operation or damage. Install Switches in locations not subject to shock and vibration and in orientations that will not produce resonance. * The Switches have physical contacts. Using them in environments containing silicon gas will result in the formation of silicon oxide (SiO2) due to arc energy. If silicon oxide accumulates on the contacts, contact interference can occur. If silicon oil, silicon filling agents, silicon cables, or other silicon products are present near the Switch, suppress arcing with contact protective circuits (surge killers) or remove the source of silicon gas. * Do not solder the screw terminals. * Sealing materials may deteriorate when used outdoors or when exposed to cutting oil, solvents, or chemicals. Check this on actual equipment and, if deterioration is foreseen, consult your OMRON representative in advance. * If the one-touch connector is to be mounted onto the switch body, lightly push up the fitting so that the switch body can then be inserted into the clamp. (2) Lightly push up the filling on the left and right side alternately. 330.15 * When mounting the panel mount-type Switch with screws on a side surface, remove the hexagonal nuts from the actuator. * When mounting the panel mount type on a panel, tighten the hexagonal nuts of the actuator to a torque less than 7.85 N*m. Mounting Hole 14.50.2 dia. * Operating method, shape of cam or dog, operating frequency, and the overtravel (OT) have significant effect on the service life and precision of the Limit Switch. Make sure that the shape of the cam is smooth enough. * Check that OT has a sufficient margin. The actual OT should be rated OT x 0.7 to 1. * Do not change the operating position by remodeling the actuator. Wiring When wiring screw terminals, M3-size round solderless terminals with an insulation tube is recommended. The conductor size should be 0.75 mm2 and cable diameter should be 7 mm. Round solderless terminals (1) Insert the switch body L l F B D dia. dz dia.: D dia.: B: L: F: l: 3.2 1.9 5.2 16.4 5.8 8.0 (mm) dz dia. Wiring Method * Be sure that the clamp is inserted to the full depth, because the Switch will not function properly if one of the clamps is improperly inserted. Confirm visually Switch body Round solderless terminal Clamp fitting * If the clamp is properly inserted up to the full depth, it will not slide out easily. Be sure to carefully confirm all the above items. 9 D4E-@N Tightening Torque A loose screw may result in a malfunction. Be sure to tighten each screw to the proper tightening torque as shown below. Appropriate No. Type tightening torque (1) Terminal screw (M3) 0.24 to 0.44 N*m (2) Switch mounting screw (M4) 1.18 to 1.37 N*m 10 Terms and Conditions Agreement Read and understand this catalog.
