Telemecanique XY2CE2A450 Latching Emergency Stop Rope Pull Switch
The Telemecanique XY2CE2A450 latching emergency stop rope pull switch is an industrial safety device used where emergency stop access must extend across a wider machine area. It is part of the Telemecanique XY2CE rope pull switch range and is designed for machinery layouts where operators may not always be standing close to a fixed emergency stop pushbutton.
Product Overview
XY2CE2A450 is a left-hand side latching emergency stop rope pull switch with a 1 NC + 1 NO contact configuration. It uses a key-release pushbutton reset, which means the device remains in its tripped state until an authorized reset is performed. This function is especially relevant in machine safety circuits, because emergency stop recovery should require a conscious inspection before restarting equipment.
The housing is red RAL 3000, with a Zamak body and stainless steel cover. The switch uses screw clamp terminals for conductors from 0.5 to 1.5 mm². It is designed without pilot light signalling and supports slow-break contact operation. The device is associated with safety standards including IEC 60947-5-1, IEC 60947-5-5, IEC 60204-1, ISO 13850, UL 508, and machinery directive requirements when correctly integrated.

Where XY2CE2A450 Is Used
This switch is commonly used on conveyor lines, material handling systems, packaging machines, transfer lines, automated processing equipment, and industrial machinery with long accessible sides. The rope allows emergency stop activation from multiple points along the machine, reducing the delay that may occur when an operator has to reach a fixed button.
Why the Left-Hand Design Matters
The left-hand anchor point is important during layout planning. Rope pull switches must be selected according to cable direction, mounting position, operator access, and the mechanical path of the trip wire. Using the correct side orientation helps maintain proper rope tension, consistent actuation, and a more reliable safety response.
Safety Integration
The Telemecanique XY2CE2A450 latching emergency stop rope pull switch should be connected to a suitable safety relay or safety controller when used in a monitored safety circuit. The normally closed contact is generally used for the safety function, while the normally open contact can support indication, diagnostics, or auxiliary signalling. Final circuit design should always follow the machine risk assessment.
Installation Notes
Correct mounting is essential. The rope should be visible, reachable, and correctly tensioned. Installers should avoid excessive sag, sharp bends, unstable mounting surfaces, or routing that can be blocked by product flow. Environmental conditions such as dust, moisture, vibration, and temperature should also be reviewed before installation.

FAQ
What is Telemecanique XY2CE2A450?
It is a latching emergency stop rope pull switch used in industrial machine safety systems.
Is XY2CE2A450 left-hand or right-hand?
XY2CE2A450 is a left-hand side model. This should be considered during mechanical layout and rope direction planning.
What contacts does this model include?
It includes 1 normally closed contact and 1 normally open contact.
How does the reset function work?
The switch uses a key-release pushbutton reset. After actuation, the device remains latched until reset with the proper key operation.
Can this switch reach PL e?
Yes, it can reach PL e when used with the appropriate monitoring system and correct wiring.
What is the protection rating?
The product is specified with IP65 protection according to IEC 60529.
What applications are suitable?
It is suitable for conveyors, packaging machinery, material handling systems, transfer lines, and other machines requiring extended emergency stop access.
Does it replace machine guarding?
No. It supports emergency stop access but does not replace guarding, interlocks, safe operating procedures, or risk reduction measures.
