DeviceNet Compliant Connector, HR31 Series (HR31-SC-121(71))
These are DeviceNet standard compliant connectors. These connectors simplify connection, reduce plug connector size, and promote differentiation compared to conventional parts.
[Features]
· DeviceNet compliant: The HR31 series is a FA network device standards product. (Terminal contacts: Gold-plated)
· Screw-lock: All screw-lock equipped products can be securely locked, allowing for increased locking strength.
· Snap-lock: The snap-lock feature creates a tactile click when mating.
· Commercially available tools can be used: These connectors are designed to be used with crimp tools conforming to JIS C 9711 standards.
· Designed to allow for removal by ⌀1 mm pin when improperly wired.
· Protected contacts: The crimped contacts are protected by the plug housing, reducing damage to the contacts during connection.

Main Features of HR31 Series DeviceNet Compliant Connector
HR31
Products made by other manufacturers
| Item | Products made by other manufacturers | HR31 |
|---|---|---|
| Reduced number of termination operations | Crimp the wire to a commercially-available cap connector and insert it into the housing and fasten with the screw. (*) | Crimp and connect onto the contact, and then fasten by simply inserting into the housing. |
| Supports high-density mounting | Plug height is 15 mm. | Because the plug height has a low-profile at just 10.2 mm, it supports higher density mounting on connector mounting surfaces. |
| Prevention of connection errors | Contact positions not identified | Permanently identified contact positions. |
| Reducing the number of required operations to secure receptacle assembly to the board | Connectors are secured from the underside of the board using screws. | No need for screws; features built-in locking pins which secure the connector to the board. |
- *Although it is possible to terminate discrete cables with screws and not use a pin contact, there are potential issues and concerns for long-term reliability. Therefore, most manufacturers recommend to use crimp contacts.
