Isn't there a problem with door locks such as 'It's difficult to open and close because it's a screw-tight type' or 'It's dangerous because it can open unintentionally since it's a push-button type'? The door lock device 'AV-2E' solves these problems! When closing, you can easily lock it with a one-touch lock by simply pressing the door lightly with your hand. When opening, it uses a tool unlocking method (just twist with a flathead screwdriver by 90 degrees), which prevents unintentional opening and ensures safety. 【Features】 ■ One-touch lock type ■ Tool unlocking method to prevent unintentional opening ■ Two-step unlocking for safety when opening ■ Can maintain a half-lock state with a slight gap open *For more details, please refer to the PDF document or feel free to contact us.

The "LEC-2" is a power supply device for driving our lifter magnet "Pittari-kun." Equipped with a reverse excitation circuit, it enables efficient magnet control. It uses voltage from a sequencer or contact signals from external relays as a start signal to energize the coil. Additionally, the coil power supply can be connected in parallel with up to four units using the LF-38N. 【Features】 ■ The presence of a start signal can be confirmed by an indicator light. ■ The power supply for the coil is compatible with both DC and AC. ■ The coil power supply can be connected in parallel with up to four units using the LF-38N. ■ To prevent residual magnetism, reverse excitation is applied when the coil power is turned off. ■ It detects overcurrent and disconnection in the coil, stopping power and protecting the circuit while displaying a lamp. *For more details, please refer to the external link page or feel free to contact us.

The "Lifting Magnet Pitta-kun" is a lifter magnet that conforms to the uneven shape of the workpiece on its adhesive surface. When not powered, the movable yoke can move freely up and down. Please use the convenient dedicated power supply LEC-2. 【Lineup】 ■LF-8N ■LF-16N ■LF-38N *For more details, please refer to the external link page or feel free to contact us.

The "Projection Magnet" is a magnetic chuck suitable for retrieving randomly stacked workpieces. Due to the protruding pole at the center of the chuck, the workpiece is less likely to detach, and even if the workpiece tilts, the coordinated adhesion with the surrounding chuck prevents it from falling off. Additionally, the tip of the protruding pole has a spherical shape, providing stable adhesion strength. 【Features】 ■ Ideal for retrieving randomly stacked workpieces ■ Less likelihood of workpiece detachment due to the protruding pole at the center of the chuck ■ Adhesion strength does not decrease even with rough surfaces like castings ■ Prevents detachment through coordinated adhesion with the surrounding chuck even if the workpiece tilts ■ The tip of the protruding pole has a spherical shape, ensuring stable adhesion strength *For more details, please refer to the external link page or feel free to contact us.
