-Original Multi-purpose High-pin-count Miniature Waterproof Connectors RM-W Series Assembly type (straight plug/RM15W) Ø23 Ø21.5 57 (Low-height plug) Cable Ø21.5 Overview RM-W series connectors originally developed by Hirose offer miniature waterproof connectors to satisfy the requirements of high-capability in a small package. The locking structure adopts a thread coupling style, showing superior waterproof reliability. Cable Fig.1 Assembly type (right-angled plug/RM15W) 41 Cable Features Plugs : Available in 3 types - straight plug, straight lowheight plug, and right-angled plug. Receptacles : Single-body waterproof type is available to satisfy waterproof requirements in a single connector. Fixing methods : Available in 2 types-Jam nut type and screw tightening type with square flange. The Jam nut types offer a front or back mount application. Available numbers of contacts : 2, 3, 4, 8, 10, 12, 15, 20, 40, and 55 contacts in 2 contact plating types: gold or silver. Ø23 Flexible cable arrangements Cable ° In RM-W series, you can select an optimal product for your application through different kinds of both plugs and receptacles. 360 1.

Waterproof structure When fully mated, the connectors meet the waterproof requirements of IP67 and IP68. Single-body waterproof receptacles also meet the requirements of IP67 and IP68. *IP67 : Submerged in 1m for 30 minutes. *IP68 : Submerged in 2m for 14 days. 3. Flexible cable arrangements The assembly type right-angled plugs permit exiting of the cable over a 360-degree range in any direction. In cases where the application will demand a high level of reliability, such as automotive, please contact a company representative for further information. 2018.7④ 1 RM-W Series● -Original Multi-purpose High-pin-count Miniature Waterproof Connectors Product Specifications (RM15WT size products) Voltage rating 600V AC, 840V DC (2 pos.) 500V AC, 700V DC (3, 4, 8 pos.) 350V AC, 490V DC (10 pos.) 350V AC, 490V DC (12 pos.)

Right-angle plugs have set screws in the tightening ring at 2 locations. Loosen the set screws before removing the back shell. 2 Remove the 2 screws of the strain relief clamp, and then remove the clamp from the tightening collar. 2. 3. 4. 5. 8 Wiring 1 Assure that the cable outer diameter will fit the strain relief clamp, and is prepared as recommended in Table 1. It is recommended that the exposed conductors be pre-soldered, to assure easier insertion in the soldering cup. 2 Pass the parts over the cable in the order of: tightening collar, washer, bushing, back shell, and coupling. Refer to the drawings (above) for assembly orientation of all components. 3Solder the wires to the contacts of the insulator body (P). Use of heat-shrink tubing or another insulating media between the soldered contacts is suggested. Connector Assembly Straight Plugs 1 Place the completely wired insulator body (P) in the assembly fixture secured in a vise. Insert in the coupling, then back shell. The back shell should be tightened to a torque of 3N•m. Right-angle Plugs 1 Place the completely wired insulator body (P) in an assembly fixture secured by a vise. Insert in the coupling, then back shell (with tightening ring). When attaching the back shell, orient the cable in the desired direction and fasten the tightening ring to the insulator body (P) with a torque of 3N•m. After this, tighten and fix the 2 sets crews with a torque of 0.2 to 0.25N•m. Additional assembly recommendations : In applications where continuous extremely high vibrations may be encountered it is recommended that a thread locking compound be applied to male threads prior to assembly (Loctite 263 manufactured by Henkel Japan K.K. or equivalent) 2Assemble in the following order : gasket then washer, then the tightening-collar. During assembly, make sure to keep the tip of the cable sheath at least 3mm from the gasket, as shown in the figure (above). 3To prevent loosening of the male threads, apply Loctite 263 (Henkel Japan K.K. or equivalent) to the male threads of the back shell. Then tighten the tightening-collar to a torque of 3N•m with the clamp and the cable so that the cable cannot rotate. (Screw-tightening torque : 0.65 to 0.70N•m) Points to be checked 1This connector has a waterproof feature. Please verify that the assembled connector is waterproof by conducting the test described below. 2Because the force required to secure the strain relief clamp differs with the cable structure, please check the connector assembly before use to make sure there is no rotation. (Test verification of waterproof capability) Apply air pressure of 17.6kPa for 30 seconds from the mating end of the plug connector. No air should leak from inside the connector. Waterproof verification - plug assembly Apply air pressure of 17.6kPa for 30 seconds from the mating side of the plug assembly. There shall not be any air leakage from inside the connector when submerged in the water tank. Precautions The waterproof capability may be impaired if the cable sheath or gasket is damaged or contaminated when performing the assembly. Please handle carefully. RM-W Series● -Original Multi-purpose High-pin-count Miniature Waterproof Connectors Receptacle - recommended panel cut-outs Rear mounting, front nut Square flange, screw mounting 20.6±0.05 +0.1 0 Ø24 +0.1 0 Ø7.6 +0.1 0 Ø19.65 +0.05 0 Ø21 20.6±0.05 .1 +0 0 Ø17 4-M3∞0.5 Ø19.2 +0.1 0 Front mounting, rear nut 1.4±0.05 Panel thickness : 0.5 to 2mm Panel thickness : 0.5 to 2.5mm May.1.2021 Copyright 2021 HIROSE ELECTRIC CO., LTD.
