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.
Features
1. Rich variation
In RM-W series, you can select an optimal product
for your application through different kinds of both
plugs and receptacles.
Plugs :
Available in 3 types - straight plug, straight low-
height 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.
2. 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.

Fix the plug in the assembly fixture (RM15TP-T01 (HRS No.150-0098-0)), then remove the insulator body (P) and the back shell.
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.
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.
3.
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-tighteningtorque : 0.65 to 0.70N•m)
4.
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.
5.
Precautions
The waterproof capability may be impaired if the cable sheath or gasket is damaged or contaminated when performing
the assembly. Please handle carefully.
