Interface Connectors for Sensing Devices

With the rapid spread of the IoT (Internet of Things), sensing devices that detect the status of humans and objects and transmit that information are essential.
As demand for sensing devices increases, there is a need for technological advancement, and various sensing devices are being developed as a result.
Hirose Electric offers a wide range of interface connectors that can be used with various sensing devices, allowing you to choose the connector that best suits your needs.

Select the Ideal Connector Based on Connection Method and Operating Environment

Hirose Electric offers a variety of original circular interface connectors that are ideal for connecting sensing devices.
You can choose the best connector for each type of sensing device, based on features important for the performance of the sensing device such as waterproof/non-waterproof, grounding method, analog or digital, and lock.

Q&A about Product Selection

■ For Analog Signal

Q．I am looking for a compact and lightweight connector that outputs analog signals from sensors.

A．The highly shielded LF Series with metal housing is recommended.

There is also HR08D Series with pins for housing (panel) ground connection

■ For Digital Signal

Q．I am looking for a compact and lightweight connector that outputs digital signal from sensors.

A．If you need a transmission speed of several hundred Mbps, HR30 Series is recommended.

If shielding performance is required, LF Series is recommended.

We can also introduce the industrial Ethernet compatible connector (ix Industrial™).

Please feel free to contact us.

■ Sensors to be Installed Outdoors

Q．I am looking for a connector for a sensor that will be installed outdoors for a long time.

A．Although the housing is made of resin, I recommend HR30 Series which can be used outdoors.

(Sunshine Weather test cleared 2000 hours, usable for approximately 10 years)

The LF Series is also available with bayonet lock and black chrome plated metal.

■ Sensors for Outdoor Use

Q．I am looking for a connector for a portable, outdoor use measuring instrument that can connect to sensors. 

A．How about the compact and lightweight HR30 Series with resin housing?

(Sunshine Weather test cleared 2000 hours, usable for approximately 10 years)

■ Sensors for Use in Heavy-Duty Environments

Q．I am looking for a connector that is easy to remove even if dust and dirt get stuck in the spaces.

A．If a bayonet lock design such as HR34B Series (PCB ground) or HR08D Series (panel ground) is used, it will be easier to remove the connector if you rotate it a little with a general-purpose tool.

Push-pull lock type connectors are not recommended because they cannot be pulled out when dirt gets stuck.

■ Compact and Lightweight Connector

Q．I don't need waterproof performance, but I am looking for a small and lightweight connector.

A．We recommend the HR10 Series (Push-Pull lock type), which is standardly used and has been adopted in a wide variety of applications.

In addition, the multi-pin count, high-density HR25 Series (Screw lock type) is also recommended.

■ Very Lightweight Waterproof Connector

Q．I'm looking for a very lightweight waterproof connector.

A．How about HR30 Series with resin housing?

The mated condition of the plug and receptacle is extremely light.

The 6 position type is a mere 6 grams and the 12 position type is only 9 grams.

■ Ultra-compact Connector

Q．We are considering replacing the direct cable portion of a small sensors with a connector.

Do you have any very small connectors?

A．Please let us know the number of pos. you want, and we will find the most suitable connector for you. 

Please feel free to contact us.

Product Lineup

■ LF Series

LF

IP67/68 waterproof in mated condition.
Robust design with metal shell and resistant to noise.
There are wide variations such as straight connection, right angle connection, soldering, crimping types and more.
LF is a bayonet lock type connector with good operability.

■ HR30 Series

HR30

HR30 Series is a small, waterproof and low-profile connector that is IP67 and IP68 compliant in mated condition.

While waterproof, the push-pull lock provides good operability.
Additionally, the plastic shell reduces weight.

■ HR08D Series

HR08D

IP67/IP68 waterproof in mated condition.
The right angle plug can be routed in 8 different directions based on 45° increments, giving you more freedom during wiring.

Two types of connection methods are available: soldering and crimping.

■ HR34B Series

HR34B

The connector is IP67/IP68 waterproof and has excellent oil resistance in mated condition (4pos. are independently waterproof).
The right angle plug can be routed in 8 different directions based on 45° increments, giving you more freedom during wiring.
The outer shell is black chrome plated for superior corrosion resistance.

■ HR25A Series

HR25A

Small, shielded push-pull lock type connector.
The maximum plug diameters are ⌀11mm and ⌀13mm, enabling size and height reduction.
The connector’s metal shell design is an optimal choice for devices that require noise shielding.

■ HR25 Series

HR25

Small shielded connector.
The maximum plug diameters are ⌀10.5mm and ⌀12.5mm, enabling size and height reduction.
The metal shell design which prevents interference from external noise is ideal for applications in which noise resistance is critical.

■ HR10 Series

HR10

Small push-pull lock type connector.
HR10 Series is widely used in devices other than sensors as well.
There are two types of lock variation available, push-pull lock and screw coupling lock.
A shielded type and built-in coaxial contact type are also available.
