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.
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.

The ABB JSTD1-E Safeball is an ergonomic safety control actuator primarily designed for two-hand control applications. Two Safeballs can be used with an appropriate safety relay or Pluto Safety PLC to create a safety system that requires deliberate operation with both hands.
The manufacturer part number for the ABB JSTD1-E Safeball is 2TLA020007R3400.
The JSTD1-E incorporates two independent normally open contacts. This differentiates it from JSTD1-A, JSTD1-B and JSTD1-C Safeball versions that use one normally open and one normally closed contact.
The ABB JSTD1-E is supplied with four 0.2 m wires designed for direct connection into an enclosure. The two independent normally open switching circuits can then be integrated into the appropriate machine safety-control system.
Yes. ABB specifically designed the Safeball range for applications including two-hand safety control. Two Safeballs used with an appropriate safety relay or Pluto Safety PLC can provide a high level of machine-safety performance when the complete system is correctly designed and validated.
ABB Jokab Safety Safeball devices provide an ergonomic alternative to conventional two-hand control push buttons, combining low operating force, flexible positioning and robust industrial construction for machinery where safe and deliberate operator control is essential.
