Product Overview
Hokuyo DMJ-GB1 IR Optical Data Transmitter Head – Used
The Hokuyo DMJ-GB1 is an infrared optical data transmission head designed for wireless parallel I/O communication in industrial automation systems.
Hokuyo equipment has long been used in AGVs, conveyor systems, and semiconductor automation, where robust signaling and predictable communication timing are essential in noisy electrical environments.
Product Condition
Used. Clean and in very good cosmetic condition based on visual inspection. No testing was performed. Listing includes only the sensor head as shown.
Product Overview
The DMJ-GB1 supports parallel 8-bit I/O signal exchange over an infrared channel, enabling wireless communication between mobile equipment such as AGVs and fixed stations. Designed for head-on transmission with a range of approximately one meter, the device uses pulse modulation and parity checking to maintain reliable two-way half-duplex data flow. It operates at 24 VDC with up to 100 mA current consumption, and its rugged housing meets IP64 protection requirements except at the connector interface.
The DMJ-series architecture aligns with communication expectations in the semiconductor industry, including compatibility with SEMI E84-style signaling. Vibration and shock resistance allow installation in moving machinery and industrial transport systems.
