2TLA020007R3400 ABB JSTD1-E Safeball

Why Choose the ABB JSTD1-E Safeball?

The ABB JSTD1-E Safeball is an ergonomic safety control device designed primarily for two-hand control applications on industrial machinery. Identified by ABB order code 2TLA020007R3400, it forms part of the ABB Jokab Safety JSTD1 Safeball range and uses a spherical actuator design that can be operated comfortably from several different hand positions.

The JSTD1-E incorporates two independent normally open contacts and is supplied with four 0.2 m wires for direct connection into an enclosure. The Safeball requires a low operating force of approximately 2 N, helping provide comfortable repetitive operation while its rounded ergonomic construction reduces the need for conventional palm buttons and surrounding protective shrouds.

When two Safeball units are used together with an appropriate safety relay or ABB Pluto Safety PLC, the system can provide a high level of safety for two-hand control applications. The JSTD1-E offers a maximum resistive contact load of 30 V DC, 2 A, IP67 protection and a compact plastic housing, making it suitable for demanding machinery and automation environments.

Ergonomic Two-Hand Control for Machine Safety

Two-hand control systems are used where machinery must only perform a hazardous movement when an operator deliberately actuates two separate controls simultaneously. By requiring both hands to operate the controls, a correctly designed safety system helps ensure that the operator's hands remain away from the hazardous machine area while the movement takes place.

The ABB Safeball concept replaces traditional flat or mushroom-style palm buttons with ergonomic spherical actuators that can be gripped and operated from several directions. When two JSTD1-E Safeballs are connected to a suitable safety relay or Pluto Safety PLC, they can form part of a high-performance two-hand control system while providing comfortable operation and flexible positioning for the machine operator.

Typical Applications

• Industrial two-hand machine control systems.
• Presses and forming machinery.
• Cutting and punching equipment.
• Assembly and production machinery.
• Packaging and processing equipment.
• Automated manufacturing systems.
• Safety relay and Pluto Safety PLC controlled machinery.
• OEM machinery requiring ergonomic two-hand operator controls.
