Overview
Features
->This is compatible with SEMI standards
->Modular cable is applied between a head and a connector of E84 parallel I/O and it is easy to make a wiring
->This device has logging function (up to 100 times data changes)
DMJ-G/HB1
This is Parallel I/O (8-bit) with RJ-11 modular cable type.
It communicates wirelessly (infrared ray) between mobile vehicles sides such as AGVs (Automated Guided Vehicles) and the station sides by using this.
This is provided with a logging function and corresponded to SEMI E84.
This composes of Head, Connector and RJ-11 cable, it is user friendly to make wiring.

*1 Product specifications other than those listed are the same as standard products, so please refer to the product specifications page.
*2 It may be necessary to notify the model to be adopted in advance.
*3 The pin assignment is compliant with SEMI E84. There are two types of fixing screws, metric screws and inch screws. Devices that support SEMI E84-0699, -0999 may use metric screws. Inch screws are specified for SEMI E84-0200A and later versions.
*4 Recommended product. The logging function is effective in investigating the cause when a transfer problem occurs. Since the log data can be easily sent by attaching it to an e-mail, it is possible to immediately analyze the defect phenomenon in-house even in the case of troubles with overseas users.
