Features
1. Device-Net Compliant
Conforms to requirements of Factory Automation Network Device-Net standards.
Hirose products are distinct from products of made others, as described below.
Feature
Reduced number of termination
operations
High density mounting
Prevention of connection errors
Number of required operations to
secure receptacle assembly to the
board
Made by others
Crimped to commercially available cap connectors,
inserted into housing and fastened by screw.
Plug height : 15 mm
Contact positions not identified.
Connectors are attached by screws from the
opposite side.
Hirose HR31
Crimped and connected to terminal then fastened
simply by inserting into housing.
Plug height is 10.2 mm, allowing use of less space
when mounting several connectors
Permanently identified contact positions
No need for screws, built-in locking pin secures
connector to the board
2 Locking features
The connectors can be supplied with either of the following
locking features:
-Screw lock, using attached screws.
-Snap lock, using built-in feature with a definite click-sensation.
Total space occupied by mated assemblies
3. Commercially available tools may be used
Use crimp tools conforming to JIS C 9711 standards.
Terminated contacts can be removed using 1 mm dia.
steel pin. and re-inserted.
