Miniature High Performance Circular Connector, HR22 Series
Caution
Product Description
This is a multi-pin round connector that uses a vibration-resistant screw-coupling structure. (The interior of the coupling is equipped with a spring that prevents loosening of the screws.) Waterproof type and non-waterproof type.
[Features]
・There are two types, waterproof and non-waterproof, and each is compatible. The internal structure of the waterproof type is such that it can operate after being submerged at a depth of 1.8 m for 48 hours in a fitted condition, with no ingress of water.
・The structure prevents lock loosening. The lock structure has a screw coupling system in which the interior of the coupling is equipped with a spring that prevents loosening.
・There are 2 wiring work systems: Crimped types and soldered types. Users can choose depending on the application.
・Receptacle installation is easy. From the panel surface, the nut fastening system makes receptacle installation fast and easy.
・There are types that also take into consideration lack of flexibility. By covering the shell with a code bushing, the bending radius is enlarged, and this prevents disconnections when the cable is flexed.
・It has a high-density layout. Although there are 20 poles, the maximum outer diameter of the plug is Ø 21, which is very high density.

Product Usage Precautions
- 1. Make sure the power is off before mating or un-mating the connector.
- 2. Because the power supply side of the circuit features a shock prevention function, be sure to use the connector female contact side.
- 3. Make sure that the coupling is in the completely locked position (fully tightened state.)
- 4.Cable clamping, cable rotation, and other forces may vary with the cable construction. Make sure that your cable is suitable for use with these connectors before usage and production.
- 5. This product uses silver plated contacts. Note that silver easily reacts to sulfur based gases, causing discoloration or degradation when exposed to certain environmental conditions such as those detailed below.
- Areas with high levels of powder dust and dirt
- Regions or areas with high concentrations of sulfur dioxide gas, hydrogen sulfide gas, nitrogen dioxide gas, etc. (Emission gases from vehicles and factories, etc.)
- Highly fluctuating temperatures, such as close to heating apparatus
It is recommended to store the products in their original packaging or similar state in order to prevent discoloration.
- Temperature: -10 to 60°C, humidity: 85% or less (An environment where temperature and relative humidity are constant and there is little temperature variation is recommended.)
- Use within 6 months of delivery. (If the storage period has expired, please examine the connectors and solder cups for corrosion and/or tarnish.)
