1 INTRODUCTION
Robot System Products is a front-rank provider of peripheral products for high performance
robot applications. We provide complete system solutions for your robot installations, aiming to
improve your productivity with the most reliable and cost-effective tooling on the market.
Continuously we explore emerging technologies, working with leading edge design.
Robot System Products has a wide range of standard robot peripheral products:
•Tool changers
•Swivels
•Swivels with integrated tool changers
•Grippers
•Hose Packages
•Valve units
•Tool systems
•Tool stands
Robot System Products’ tool changers are constructed to maximize the flexibility and reliability
of your robot fleet. Through our patented locking device TrueConnect™ robustness and high
safety are combined with low weight and compactness. With our swivels you can provide
compressed air, water, electrical and data signals as well as weld and servo power to your tools
with robot motion capabilities fully maintained. Our swivels with tool changers unites the
TrueConnect™ tool changing mechanism with our swivel technology, combining the best out of
two technologies.
Robot System Products’ product lines are available for all major robot brands and come with
complete documentation. 3D-models for simulation are available for download at:
www.rsp.eu.com.

1.1 Safety
1.1.1 General
The integrator installing the tool changer into the system must follow the safety demands stated
in standards and provisions applicable in the country where the tool changer system is to be
installed. The products are all prepared for CE-certification.
The user of the Robot System Products tool changer is responsible that law and directives
applicable in respective countries, with regards to safety, are followed. The user is also
responsible to guarantee that all safety devices are installed correctly.
WARNING!
Never carry out service work on a robot that has not been taken out of operation.
See safety information for the robot.
WARNING!
Only perform work on grippers or tools attached to the tool changer if the air
pressure is safely switched off.
WARNING!
Be aware that tool changer and tool attachment are heavy and may cause
personal injury and equipment damage if dropped.
NOTE!
The tool changer shall always be in locked position, also when empty, to avoid
unexpected locking if air pressure is lost.
1.1.2 Explanation of warnings
The warnings in this document are specific to the products in this manual. It is expected that the
user also pay attention to certain notifications from the robot manufacturer and/or the
manufacturers of other components used in the installation.
WARNING!
The warning sign will make you aware that a situation could result in potential
serious injury or damage to equipment.
NOTE!
The note sign will alert you about something important to consider.

1.2 Description of RSP tool changers
Our tool changers enable robots to handle and switch between multiple tools. They are built to
ensure reliable and smooth operation, being compact with low weight and robust design and
incorporating many safety features. Depending on model and options, electrical signals, weld
and servo power, data, water and compressed air are transferred from the robot side to the tool.
The patented locking device TrueConnect™ has a minimum of play and gives a practically,
through the lifespan, absolute positioning repeatability. The principle behind the locking
mechanism is the uniform distribution of load obtained by pressing looking balls into spherical
grooves. In consequence, substantially larger positional tolerances are accepted during docking.
1.3 Complementary Equipment
Complementary equipment is described in separate documents.
Article
Note
Cable and Hose Package
Complete packages for most robots on the market ready to be
mounted without any modifications.
Tool Stands
Tool stands will, combined with tool attachments and
adaptation kits, give a rigid installation for easy tool changing.
Connection kits
In order to make electrical installation easier, connection kits
are available for tool changers and tool attachments.
3D-models
Available in Solid Works® and STEP-format.

2 TECHNICAL SPECIFICATIONS
2.1 Description of tool changers and tool attachments
This document presents the Robot System Products TC250-8 and TC250-8E tool changers
including tool attachments dedicated for material handling. Likewise presented are adaptation
kits, connection kits to facilitate electrical installation and a tool stand kit.
The tool changer TC250-8 transfers compressed air to the tool. It can be equipped with transfer
of electrical signals, via spring loaded signal pins, to the tool attachment. The electrical version is
designated ’E’. The tool changers TC250-8 and TC250-8E cannot transport fluids.
The spring loaded signal pins of TC250-8E are placed and protected at the centre of the tool
changer. The contact surface of the tool attachment and the signal pins are not in connection
until at the very end of the docking cycle when the tool attachment is already properly aligned.
This guarantees a minimum of wear of the contact surfaces.
The electrical unit is primarily intended for transfer of sensor signals from grippers. In addition it
can be used for checking the presence and identifying tools by using signal jumpers and binary
coding of signals on the tool attachment.
For other bolt circles adaptation plates between the tool changer and the turning disc on the
robot may be needed. Such adaptation plates are available from RSP.

2.1.1 Coordinate System Definition
A tool changer adds load to the robot. If the arm and tool loads are not stated correctly during
programming the behaviour of the robot and the wear of the equipment will be affected.
Information about weight and centre of gravity can, in accordance with the co-ordinate system
stated below, be found in the technical specification tables of the tool changer.
NOTE!
For the tool changer and tool changer with tool attachment, the origo is situated in
the centre of the robot mounting flange.
