Rail Connectors Support Reliable Power and Data Transmission

Wesgarde has expanded the visibility of Schaltbau's portfolio of heavy-duty connectors designed for power and signal transmission in railway, utility and industrial systems. The connector families address applications requiring standardized, high-reliability electrical interfaces while reducing installation effort through pre-assembled cable assemblies and modular designs. The portfolio supports OEMs, vehicle manufacturers and infrastructure operators seeking robust industrial connectivity solutions for demanding operating environments.

Railway Connectors for Braking and Train Communication
The Schaltbau EP series is designed for electro-pneumatic braking systems and emergency brake bypass functions in railway vehicles. The connectors comply with the UIC 541-5 VE railway standard and incorporate an integrated pilot contact that provides confirmation when connectors are fully mated. Pre-assembled single-ended and double-ended hybrid cables eliminate manual field wiring, reducing installation time and minimizing commissioning tests.

According to Schaltbau, the EP connectors support both power and signal transmission with up to nine main contacts plus two auxiliary contacts. The series operates at a rated voltage of 250 V, provides IP69K protection when connected, withstands more than 10,000 mating cycles and is designed for operating temperatures from -50 °C to +80 °C. Contact resistance is specified at 2 mΩ or lower, supporting reliable electrical performance in harsh railway environments.

The UIC and UIC-IT connector families extend connectivity to railway communication networks. The UIC-IT version integrates an 8-pole Gigabit Ethernet module with optional signal contacts, enabling data transmission for passenger counting systems, onboard video surveillance, wireless networking and train control functions. Break-away jumper designs protect equipment by separating safely if connected railway vehicles move apart unexpectedly, while factory-assembled cable sets reduce installation complexity. These features support the growing digital railway infrastructure and train data networks.

Standardized Train Line and Multiple-Unit Connectivity
The ZH series complies with the UIC 552 standard for train line connections between locomotives, passenger coaches and multiple-unit vehicles. The redesigned ZS552 receptacle incorporates a symmetrical housing and a common cable terminal that simplifies cable routing from multiple directions. Front-removable inserts improve maintenance accessibility, while optional lock-and-key mechanisms provide additional operational security.

The connectors employ non-halogen cables tested for high-voltage railway applications and support conductor cross-sections up to 185 mm². Schaltbau specifies test voltages exceeding 11.5 kV, operating temperatures from -50 °C to +85 °C and mechanical endurance of approximately 5,000 mating cycles, supporting long service life in cross-border railway operations.

For multiple-unit road and railway vehicles, the B series combines power and control circuits within a modular connector system supporting operating voltages up to 600 V DC and 400 V AC. Configurations with up to 59 contacts plus protective earth enable additional functions such as interlocking circuits while reducing wiring complexity through factory-assembled cable options. This approach can simplify vehicle assembly and maintenance for OEM manufacturers.

Industrial Connectors for Utility Applications
Outside the railway sector, Schaltbau's G series targets medium-voltage transformer and switchgear cabinets used in utility and industrial power distribution. Connector layouts support up to 32 contacts plus protective earth, with ratings reaching 400 V and 120 A.

Pre-assembled receptacles and plugs use potted inserts, configurable polarization and bayonet locking mechanisms to provide sealed electrical connections suitable for equipment expansion, modernization and maintenance. These characteristics make the connectors suitable for industrial power distribution systems where reliable field connections are required.

Factory-Assembled Connectivity for Simplified Installation
A common characteristic across the connector portfolio is the use of factory-assembled cable assemblies. This approach reduces manual wiring operations, lowers the likelihood of installation errors and decreases commissioning time compared with field-terminated connectors. Standardized assemblies also simplify maintenance by allowing connectors to be replaced without rewiring individual conductors.

Wesgarde distributes these connector families alongside engineering support and customized assemblies for OEMs operating in transportation, industrial automation, marine, construction, agricultural equipment, food processing and alternative energy markets.

Additional Context: This section details the technical specifications and competitive benchmarking not included in the original product announcement.
Heavy-duty railway connectors are generally evaluated using measurable criteria including compliance with international railway standards such as UIC 541-5 and UIC 552, ingress protection, mechanical endurance, operating temperature range, current capacity and resistance to vibration and environmental exposure. Schaltbau's EP connectors provide IP69K protection, more than 10,000 mating cycles and compliance with UIC 541-5, while the ZH series complies with UIC 552 and supports high-voltage train line applications.

Comparable connector portfolios are available from TE Connectivity, whose UIC 541-5 railway connectors also comply with the international braking standard and offer aluminium housings, IP66 protection and versions with integrated switching contacts for inter-vehicle railway applications. Selection between suppliers typically depends on compatibility with existing railway standards, environmental protection ratings, maintenance requirements, available pre-assembled cable systems and lifecycle support rather than on a single performance parameter.
