Saving Cost and Time with Spring Clamp Terminals
Features of Spring Clamp Terminals
The spring clamp terminal block does not require screws. Easy wiring without a screwdriver is possible thanks to the spring pressure on the conductive part.

Example application: Reducing screw tightening work as well as saving wiring, cost, and time for control panels and devices
-
Case.1:
Wiring work to the spring clamp terminals is reduced by 99% via improvements to two installation steps.
-
Wiring is easy with push-in connections, but each wire is small making wiring and terminal processing difficult.
We can eliminate this hassle.
Wiring work can also be greatly reduced by combining the spring clamp junction terminal block and the digital signal converter (terminal module).
-
Case.2:
Replacing the spring clamp for the connector module saves cost, time, and space as well as ensures consistent connections.
-
I want to use spring clamp terminals in all control panels.
Connector modules can be installed separately and replaced with spring clamps without the need for other modules.
Spring clamp terminals do not require you to make your own connector cables, which eliminates the need for soldering.
-
Case.3:
Moving installation from inside the control panel to inside the device
-
Installation in the device helps reduce the size of the control panel and reduce wiring work in the panel.
Wiring from the control panel to the device can be easily performed using network cable, and maintenance can be improved by installing these cables, for example, close to the sensors in the device.
This network cable makes wiring easy when expanding.
-
Case.4:
Easy to wire stroke limit and proximity dog signals
-
A dedicated terminal block can reduce the number of wires needed and significantly reduce the installation space.
Wiring can also be reduced by using spring clamp terminals.
-
Case.5:
Conversion to spring clamp terminals on the connector module saves cost and time and ensures consistent connections.
-
Replacing with spring clamp terminals means you do not need to make your own connector cables, which eliminates the need for soldering.
The dedicated tools enable anyone to easily modify cables, which reduces labor to perform this work and improves connection stability without the need for specific skills.
Using spring clamp terminals means you do not need to make your own connector cables, which makes it easy to add signals.
-
Case.6:
Reduced wiring, cost and time, and space needed to build brake circuits for servo motors with a brake.
-
Our recommended brake sequence circuit is built in so that brake circuits for servo motors with brakes can be built in less space with reduced wiring, cost, and time.
-
Case.7:
Efficient system building thanks to a modular design in 1-channel increments and selectable number of points [Digital Signaling]
-
With a single digital signal converter (terminal module), you can convert different voltage loads into a 24VDC load, which optimizes the number of connected programmable controller modules and reduces the cost of spare modules.
You can eliminate the inefficiency of having unused channels by building systems with modules in 1-channel increments and selecting an installation base unit by number of channels.
Using spring clamp terminal blocks and dedicated cables reduces wiring work by 99%.
Using network interface modules enables installation inside each system instead of inside the control panel.

Case.8:
Efficient system building thanks to a modular design in 1-channel increments and selectable number of points [Analog Signaling]
-
Since modules can be individually specified, systems can be configured with a minimum number of points.
Installing dedicated cables reduces work.
This reduces the number of programmable controller modules, which also reduces cost of spare modules.
Using spring clamp terminal blocks and dedicated cables reduces wiring work by 99%.
Using network interface modules enables installation inside each system instead of inside the control panel.
-
Case.9:
Installing in close proximity to sensors facilitates optimization of the control panel and reduces maintenance work.
-
Combining network interface modules with analog signal converters enables installation of devices near sensors and solenoid valves at each process. This reduces wiring work and makes maintenance easier.
Sensor information can also be collected and signals are converted to control solenoid valve fluid.
