This unique design provides gentle yet secure gripping, making it ideal for handling sensitive or irregularly shaped objects without causing damage.

This model has a size of 120 and is made from blue TPE-U (Thermoplastic Polyurethane) material, which provides high wear resistance, durability, and good chemical resistance. It features a push-in fitting for simplified installation, along with an integrated one-way flow control mechanism to ensure precise and reliable operation. It has a corrosion resistance class (CRC) of 2, indicating suitability for moderate corrosion environments. The gripper finger can be mounted in any position, offering flexibility in system design.

It is designed for a wide operating temperature range of 10 to 50 °C. The DHAS-GF-120-U-BU is RoHS compliant and free from brass and PTFE. Weighing approximately 29 grams, this innovative gripper finger enables low-vibration transport and impact-free placement of workpieces, making it a versatile choice for applications requiring adaptable and durable gripping performance.
