Digital Switching

(Showing 7 of 7)

Techna offer a range of automotive CAN-based, SAE J1939 compatible digital switching products, including load controllers, keypads, rotary encoder switches and display controllers, that enable the simple integration of multiple digital switching systems in various automotive applications, such as commercial vehicles, construction equipment, work trucks, busses, agricultural equipment and military vehicles. Our fully customisable and programmable digital switches feature programmable illumination, diagnostic feedback and extended life. Multiplexing is made easy using rear mounted Deutsch® connectors, eliminating the extra weight and cost of traditional wire harnesses.

We also offer Multiplexed CAN/LIN Switching Systems that feature a Local Interconnect Network (LIN) switch module and a CAN/LIN controller module. These controller modules accommodate up to 3 LIN buses for a total of 45 switch functions in one system.

Solid State Load Controllers

Our compact CLTM12-S Series Solid State Load Controllers feature 12 high-side outputs, 4 digital inputs, 3 discrete inputs, 2 address lines and a CAN baud rate select line. These solid state load controllers provide fast, low-loss, solid state ON/OFF switching along with short circuit protection for each output, as well as load status and power diagnostics. Our CLTM12-S electronic control modules increase thermal efficiency by providing lower power dissipation and higher power-to-weight densities and also provides improved safety and reliability while reducing equipment downtime, operator workload, overall vehicle weight and wiring complexity.

J1939 Multiplexed Operator Control Modules

The VM-Series J1939 Multiplexed Operator Control Modules are ideal for construction, agriculture and commercial vehicles. These multiplex switches are rugged, sealed to IP68, can be used in open or closed cab environments and can connect to industry standard SAE J1939 CAN Bus protocol. Our VM-Series multiplex switches reduce the complexity and cost of traditional wire harnesses, increase product life and reliability and improve assembly efficiencies. Our multiplexed operator control modules have been developed in conjunction with the Contura® family of switches, providing the look and feel of our traditional rocker switches, but offering the benefits of a multiplexed product in either a 3 pod or 6 pod configurations.

J1939 CAN Bus Customisable Keypads

Our CKP-Series J1939 CAN Bus Customisable Keypads are compliant with SAE J1939 CAN standards and feature laser etched legends and up to three dimmable LED function lights per button, which also offer diagnostic feedback by blinking if there is a fault. These CAN Bus customised keypads are sealed to an IP69 protection level and can be installed inside or outside the cab making it ideal for any on-road or off-road applications. Our CKP-Series keypads have a low-profile design which gives a seamless dashboard look and can be mounted either vertically or horizontally, they also offer significant advantages over traditional electromechanical switches, such as 1,000,000 actuation cycles, reduced wire harnessing and easy installation.

The UKP-Series J1939 CAN Bus Customisable Keypads are compliant with SAE J1939 CAN standards. Each keypad button features a laser etched legend, up to three dimmable LED function lights and audible feedback when pressed. These CAN Bus customisable universal keypads have IP67 sealing protection for above panel components, so can be installed inside or outside the cab of a wide range of automotive applications. Our UKP-Series universal keypads have a low-profile design, can be installed either vertically or horizontally and are available in a wide variety of button layout configurations.

Rotary Encoder Switches

Our CRS-Series Rotary Encoder Switches feature IP67 sealing above the panel and have a mechanical and electrical endurance rating of 500,000 cycles, making them ideal for work trucks, busses, mining, agricultural equipment and construction vehicles. The CRS-Series rotary encoder switches are available with an operating voltage rating of 3.3V DC or 5.0V DC and with a 4-way directional, rotary and push button input, a rotary and push button input or a rotary only input. For a complete CAN solution, please see our Jog Switches.

J1939 Jog Switches

The CKJ-Series J1939 Jog Switches feature a joystick rotary encoder with a push-to-select button and 5 customisable function buttons with dimmable lighting. This CAN J1939 compatible display controller is sealed to IP67 standards and can be configured in a variety of orientations providing simple installation and connectivity. The buttons allow for quick access to the five customisable functions with illumination options in white, green, yellow, blue and red. Typical applications include commercial vehicles, construction equipment, agricultural equipment and work trucks.

Multiplexed CAN/LIN Switching Systems

Our CM-Series Multiplexed CAN/LIN Switching Systems feature a LIN switch module and a CAN/LIN controller module. The switch module includes a carrier that accommodates up to three uniquely identifiable switches and rheostats. The carrier also features two LIN connectors, one that connects to the controller module and one that allows for daisy chaining to other switch modules. Additionally, the carrier can accommodate a two pole hardwired switch. The controller module acts as the CAN interface to the system ECU and the LIN switches and it accommodates up to 3 LIN Buses for a total of 45 switch functions in one system.
