■Features The CA350-011 is a servo amplifier for driving direct-acting servo valves. It controls the displacement of the servo valve's spool position in proportion to the command input voltage. It employs a PWM method for output, enabling stable high-speed drive. The displacement signal from an LVDT sensor installed on the spool part of the servo valve is fed back as a voltage value, allowing for high-precision control. The main circuit board is housed in a compact and lightweight resin case measuring 100×139mm. The input voltage is +24V, and power can be supplied either from the rear connector or the bottom DIN rail. When using the DIN rail, it is also possible to connect and configure multiple amplifiers in parallel to power the entire system collectively. For command signal input, either the BNC terminal on the panel or the D-sub terminal for monitoring can be selected. The monitoring output uses this D-sub terminal to output displacement monitor values and current monitor values as voltage equivalents. Additionally, by using an externally connected switch, the output can be directly turned on or off.

• Pressure Control

Introducing the ultra-compact three-way valve of the "Nozzle Flapper Type Pneumatic Servo Valve" using a torque motor in the electric-mechanical conversion section. The driving principle is similar to that of a standard nozzle flapper type pneumatic servo valve as follows: When current is applied to the coil, torque is generated according to the polarity and magnitude of the current due to the magnetic relationship with the upper and lower magnetic poles, tilting the armature. A gap is pre-established between the nozzle and the flapper, and the air pressure is controlled by changing the opening of the nozzle sections on the supply and exhaust sides in response to the movement of the flapper. By miniaturizing the valve, it also contributes to the overall downsizing of the equipment it is mounted on, and it is considered suitable for small robots and other animatronics. 【Features】 ■ High-speed response (above 400Hz) ■ Low drive current ■ High resolution and low hysteresis ■ No sliding parts for long lifespan ■ Compact, lightweight, and small flow control *For more details, please refer to the PDF document or feel free to contact us.

The nozzle flapper type servo valve "AS121-106" uses a torque motor in the electrical-mechanical conversion section and is a low-noise type four-way valve composed of a variable resistor (nozzle flapper) and a fixed resistor (slit orifice). The slit orifice forms a flow path in conjunction with the variable orifice, which is the nozzle. Unlike a conventional orifice that is a contraction orifice, the slit orifice creates an expanded flow through slits from the center to the outer circumference, thereby reducing the flow from the inlet to the outlet. By reducing the supersonic flow at the outlet, it stabilizes the orifice and minimizes noise in the control pressure. 【Specifications】 ■ Rated pressure: 600 kPa ■ Rated flow rate: 28 NL/min ■ Rated current: 100 mA *For more details, please download the PDF or feel free to contact us.
