Electromechanical Linear Actuators With Embedded SAE J1939 Interface For Mobile Off-Highway Applications
Posted by on
Thomson (US) introduced its Electrak MD electromechanical linear actuators with an embedded SAE J1939 interface. They are suited for mobile off-highway, material handling, and factory automation applications.
The integrated features reduce space consumption by keeping external equipment (e.g., encoders, switches) within the actuator housing. This functionality provides straightforward control and communication methods.
Besides the CAN Bus connectivity, the actuators with up to 2 kN of force offer such functions as feedback on position, low-current switching (PLC compatibility), and end-of-stroke indication output. Further features include open-loop speed control, overload protection, voltage, and current monitoring, dynamic motor braking, and temperature compensation.
A power supply of 12 VDC (9 VDC to 16 VDC) or 24 VDC (18 VDC to 32 VDC) is required. The operating temperature ranges from -40 °C to +85 °C. In combination with the maximal IP69K/IP66 (static/dynamic) protection, the actuator will operate reliably in very harsh environments. The central application fields include automated guided vehicles, logistics trains, workstations, packaging machines, and agricultural vehicles. The latter include gardening and landscaping vehicles, as well as seeding, watering, and fertilizing machines.

SAE J1939 Starter Kit And Network Simulator
Our JCOM.J1939 Starter Kit And Network Simulator is designed to allow the experienced engineer as well as the beginner to experiment with SAE J1939 data communication without the need of connecting to a real-world J1939 network, i.e. a diesel engine. It may sound obvious, but in order to establish a network, you need at least two nodes, and that fact applies especially to CAN/J1939 where the CAN controller will basically shut down after transmitting data without receiving a response. For that reason, our jCOM.J1939 Starter Kit And Network Simulator consists of two J1939 nodes, namely our jCOM.J1939.USB, an SAE J1939 ECU Simulator Board With USB Port.
The jCOM.J1939.USB gateway board is a high-performance, low-latency vehicle network adapter for SAE J1939 applications. The board supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP).
