BH12 Series/20A Current, Compact, Waterproof Power/Signal Hybrid Connector

Overview
The BH12 Series is a power/ signal hybrid connector ideal for the battery connection of micro- mobility applications.
BH12 can also be used in other industrial applications as well. The BH12 Series is an IPX6/ IPX7 waterproof connector( when mated) with lock lever design and enhances cable wiring efficiency. Additionally, the power/ signal hybrid design
contributes to reducing connector occupied mounting space.

The lock lever is locked in one action: simplypush the plug straight into the receptacle. Thelock lever on both sides of the plug prevents
cable entanglement, lock deformation and damage
during cable assembly and transportation.

Lock Supports Both Ends

7. Light weightAug.1.2024 Copyright 2024 HIROSE ELECTRIC CO., LTD. All Rights Reserved.

The lightweight of 7g ( plug+ receptacle)
contributes to equipment weight reduction as well
as reduced power consumption of micro- mobility
applications.

8. Both front and rear mountavailable
The receptacle is available in both front and rear
mount types for selection based on the usage
conditions. The front mount type is effective for
reducing space used inside the panel. With therear mount type, pre- assembled cable assemblies
can be attached to the panel. Additionally,screws are not visible from the panel exterior.

9. Height inside panel isreduced by connecting thepower contacts at a rightangle.
The power contacts on the receptacle side aresoldered at a right angle, contributing to height
reduction inside the panel.

BH12 Series/20A Current, Compact, Waterproof Power/Signal Hybrid Connector■Tools・Use tools designated by Hirose when crimping.
・Crimping performed using tools other than those specified is outside the scope of warranty.
・The operating instructions are available for the crimping machine and the applicator. Be sure to carefully read theoperating instructions manual before beginning work.

■Applicable Cables

Aug.1.2024 Copyright 2024 HIROSE ELECTRIC CO., LTD. All Rights Reserved.

Check that the cables to be used are within the applicable range.
If you intend to use a cable other than those recommended, contact a sales representative.
[ Precautions]• Cables applicable to crimp connectors are tin- plated stranded soft- copper wire.
• Avoid crimping solid wire, wires with polyester threads or tin coated wires.
• Avoid crimping two cables together.
• The crimp height setting values ( Note) may vary depending on the difference in the core wire confi guration even if thecomputed cross- sectional area is the same.
Note : The crimp height is an important item that determines crimp quality. Hirose conducts crimp testing on each wire in order to set the optimum crimp height
accurately.

Precautions when using Connectors
1. When assembling the connector and installing to equipment, refer to the separate procedure manual and drawings.
Please also make sure to use the specified tightening torque. If the torque is too low or high, it may result in looseningor product damage. ( Contact a Hirose sales representative for the procedure manual. )2. Once mated, pull lightly on the cable to confirm the mated status and that the connector does not come off.
3. Excessive external force applied to the connector may cause deformation or damage, resulting in poor conduction orwaterproofing performance issues. Please avoid forceful insertion/ removal, impact and pulling, routing or twisting of
the cables. Also, when routing inside equipment, make sure to provide sufficient slack to the cable so that a load
is not applied directly to the connector such as through excessive cable bending or tension on the cable.
4. When packing and storing assembled products, make sure not to apply excessive load on the spring portion of the pluginsulation case due to connector overlapping. If the lock is left in a high temperature and high humidity environment fora long period of time with a load applied, the lock may deform resulting in mating failure.
5. Damage of the waterproof seal or waterproof surface may result in issues with the waterproof performance, so pleaserefrain from using a damaged product.

While Taking into Consideration
Specifications mentioned in this catalog are reference values.
When considering to order or use this product, please review the Drawing and Product Specifications sheets.
Use an appropriate cable when using the connector in combination with cables.
If considering usage of a non- specified cable, please contact your sales representative.
If assembly process is done by jigs & tools which are not identified by Hirose, the warranty of the product may beaffected.
If considering usage for below mentioned applications, please contact your sales representative.
In cases where the application will demand a high level of reliability, such as automotive, medical instruments, publicinfrastructure, aerospace/ defense etc. Hirose must review before assurance of reliability can be given.
