Applications we serve

Railway applications

Crouzet produces high performance railway components for rolling stock and infrastructure safety and reliability.

Rail Coupler

A rail coupler is a mechanism for joining rolling stock in a train. Crouzet Switches detect if two wagons are properly connected by the metal hook and checks the wire connection between them. This ensures complete rolling stock safety & integrity.

Master Controller

A Master Controller needs highly precise & reliable mechanical position sensors to quickly detect the different movements operated by the driver.

Access Ramp

A compact motor actuates the automatic step or access ramp allowing passengers to get in/out of the train safely by avoiding any accident between the train and the platform. Limit Switches withstand harsh conditions to provide information regarding automatic step position status.

External Doors

A PBX Microswith detects the train doors status whatever the conditions (dust, water, shock, vibration), the doors' speed and operating cycles. DCmind Brushless motors with integrated electronics ensure smooth and reliable open/close operation. They enable acceleration/deceleration curves settings and smooth software-enabled emergency mode management.

Internal Doors

For inter-vehicle electromechanical train doors, DCmind Brush motors offer low noise and easy to maintain actuation operation. DCmind Brushless motors with integrated electronics can also be integrated, bringing smart functionalities. A PBX Microswitch is mounted to detect accurately the door position. Pneumatic internal train doors require a robust pneumatic push button for closing/opening operation.

Emergency Brake

The emergency brake handle allows passengers or drivers to stop the train as quickly as possible in case of an emergency. Our switches ensure quick switching operation for emergency brake handle in order to stop the train immediately. They allow reliable switching even under low frequency of use.

Switchgear

A switchgear is a combination of electrical disconnectors, fuses and/or circuit breakers used to isolate electrical equipment. It is used both to de-energize equipment to allow work to be done and to clear faults downstream. A PBX microswith is used as a safety switching element.

Earth Switch

A PBX Microswitch is used as a switching element for safety grounding of electric power circuits (AC or DC) of a traction vehicle, keeping workers safe before any maintenance process.

Circuit Breaker

A PBX Microswitch might be used either as a fast changeover switching element to reverse the circuit or to allow disconnection of the circuit of traction vehicles. Our highly protected motor solution with specific gearbox actuates the circuit breaker.

Contactor/Disconnector

A PBX might be used either as a fast changeover switching element to reverse the circuit of the locomotive or to allow the circuit traction vehicles disconnection. Our highly protected motor solution with specific gearbox actuates the disconnector.

Toilet Module

A drop-in module for a toilet on a train requires a logic controller to be monitored and to share data to facilitate maintenance processes.

Applications we serve

Railway applications

Crouzet produces high performance aircraft components and has secured over the years a leading role in six product lines and services.

Platform Screen Doors

They have to move quickly and conveniently, ensuring safety, security and comfort for passengers, even in extreme conditions. A motor with encoder is used used to precisely control the doors' movements coupled with a worm gearbox for specific torque. A PBX Microswitch detects the position of the doors.

Automatic Step

A compact motor actuates the automatic step or access ramp allowing passengers to get in/out of the train safely by avoiding any accident between the train and the platform. A limit switch withstands harsh conditions to provide information regarding the automatic step position's status.

Automatic Barrier

An automatic barrier requires a powerful and robust motor that ensures its reliable open/close operation. The detection of the position of the barrier as well as a safety function might be operated thanks to a robust switching element.

Rail Construction Engine

Monitors the structure of the rails and detects any possible damage. Logic controllers save construction information and data from the machine for maintenance purposes.

Switchgear

A PBX microswitch is used as a safety switching element with the following purposes: to reliably cut the current (NC contacts), run the current (NO contact) or invert current thanks to its changeover functionnality.

Earth Switch

A PBX microswith is used as a switching element for safety grounding of electric power circuits (AC or DC) and keeping workers safe before any maintenance process.

Contactor/Disconnector

A PBX microswitch might be used either as a fast changeover switching element to reverse the circuit of the locomotive or to allow the disconnection of the circuit.

Circuit Breaker

The PBX switching solution may cut alternating current or direct current to disconnect the electric circuit of the traction vehicles whatever the type of current (high or low). Its Positive Break System ensures high reliability.

Switch Point

The PBX microswitch has two main functions: first it detects the position of the switch point ensuring safety information whereas a switching contact element allows to actuate the movement of the switch point. Our DC Brushless motor actuates the switch point with high resistance against severe conditions such as shocks & vibrations. For load measurement, a load pin is integrated within the switchpoint as a safety device to measure the maximum operating weight.
