ABB jstd25k

Why Choose the ABB JSTD25K Two-Hand Safety Control Device?

The ABB JSTD25K is a pre-built two-hand safety control device from the ABB Jokab Safety range, designed for industrial machinery where deliberate simultaneous operator control is required. It combines two ergonomic JSTD1-B Safeball actuators with a dedicated emergency-stop control to provide a complete operator station for machine safety applications.

The two JSTD1-B Safeballs are positioned at opposite ends of a 44 × 88 mm extruded aluminium profile designed specifically for two-hand applications. Protective flanges surround the Safeballs to help prevent accidental operation and protect the actuators against mechanical damage, particularly where the control station is used as a mobile device.

A Smile 10 EK emergency-stop button is mounted on top of the station, giving the operator an accessible emergency-stop function alongside the two-hand controls. The Safeballs and emergency-stop button are pre-wired to an 8-pole M12 male connector, simplifying installation into compatible industrial machine safety systems.

Key Advantages

• Complete two-hand safety control station supplied pre-built and pre-wired.
• Uses two ergonomic ABB JSTD1-B Safeball actuators.

Two-Hand Control with Integrated Emergency Stop

Two-hand control devices are used on machinery where an operator must deliberately actuate two controls as part of the machine safety function. By positioning the controls so that both hands are required for operation, an appropriately designed safety system can help keep the operator's hands away from the hazardous area while the controlled machine function is initiated or maintained.

The ABB JSTD25K combines this Safeball-based two-hand control arrangement with a top-mounted Smile 10 EK emergency-stop button. All three operator controls are pre-wired to the same 8-pole M12 male connector, providing machine builders and safety-system integrators with a compact and installation-friendly operator station for industrial machinery.

Typical Applications

• Industrial two-hand machine control stations.
• Press and forming machinery.
• Assembly and production equipment.
• Automated manufacturing machinery.
• Machine loading and operating stations.
• Fixed operator-control installations.
• Mobile two-hand machine control stations.
• Applications requiring two-hand actuation with an integrated emergency stop.
