When the Do not use the Sensor in an environment subject to corrosive or load and Sensor are connected to separate power supplies, be combustible gas. sure to turn ON the Sensor first. ● Wiring ● Others If no linear output is used, cut the gray lead wire short and apply Make sure the Sensor does not get wet. insulating tape to the lead wire so that it will not come into contact with any other terminal. ● Mounting • Do not apply a tensile strength in excess of 50 N to the cables or connectors. • The pressure port (made of aluminum die-cast) is fixed with tapered R(PT) 1/8 male screws and M5 female screws. When using tapered screws, use tapered Rc(PT) 1/8 female screws. • Wrap the tapered R(PT) 1/8 male screws with sealing tape to prevent any leakage. Tighten the male screws to a torque of 10 N·m max. • Tighten M5 female screws to a torque of 2 N·m max. • Tighten each male screw by using a 12-mm wrench to hold its hexagonal head, not its body. E8F2 Hexagonal head • When attaching the Mounting Bracket to the Sensor, make sure that each M3 screw is tightened to a torque of 0.5 N·m max. 6 E8F2 Dimensions (Unit: mm) Sensors E8F2 Display panel 28 (29) (17) 1.5 27 2 25.5 98 Two, M3 depth 6 Pressure port R(PT) 1/8 M5 depth 8 28 27 20 13.5 5 20 20.5 4-dia. vinyl-insulated round cable with 5 conductors 2 (Conductor cross-section: 0.15 mm , Insulator diameter: 0.9 mm), Standard length: 2 m 6 Mounting Hole Dimensions With Mounting Bracket Attached Two, M3 20.5 29 15 27 5.4 20 20 42 28.5 15 Accessories (Order Separately) Mounting Bracket E89-F3 20.5 9 15±0.4 Two, 3.5 dia. 27 20 Four, R1 14.5 13.5 20 45˚ 26.9 4.5 Two, 3.5 dia. 90˚±0. 5 R7.25 Note: Provided with the E8F2. 1.6 Four, R2.5 R1.6 max. 7 E8F2 Panel-mounting Bracket Panel Cutout Dimensions E89-F4 20.65 Spacer Mounted Spacer Not Mounted 12.15 +0.5 +0.5 36 0 33 0 +0.5 +0.5 36 33 0 0 Panel* Panel* 25 17 4 40 41.3 Note: Spacer provided. 40 20 11.5 Spacer * Applicable panel thickness: 1.2 to 4 mm Note: The spacer can be removed from the Panel-mounting Bracket.
