CBTH0BG Push-Pull Connector for Railway Signaling Relay Test Equipment 2026: 0B 5-Contact Elbow Plug
The CBTH0BG-SMSM05-D52B is a CBTH0BG push-pull connector for railway signaling relay test equipment — a 0B right-angle (elbow) cable plug with five low-voltage contacts, male solder contacts, a push-pull locking system, a cable collet with bend relief, a cable outside diameter range of approximately 4.3–5.2 mm, IP50 protection, operation from -45 °C to +125 °C, vibration resistance of 10~20,000 Hz at 15 g and more than 5,000 mating cycles. Every specification in this guide is backed by the railway test equipment interconnect engineering of Spring Technology.
Pain point: Routing a test harness out of a compact relay tester — where a straight cable exit would foul the display or the next interface, leads are re-plugged at every relay unit, and the joint has to survive being coiled into a carry case between depots?
Core answer: The CBTH0BG-SMSM05-D52B is a right-angle connector that can support portable railway signaling relay test equipment — its five low-voltage contacts, push-pull locking system and compact angled design make it a practical option for detachable test cable assemblies. Railway signaling systems rely on electrical relays to control and monitor essential functions including track occupancy indication, signal switching and interlocking operations, and during installation, inspection and maintenance technicians use portable relay test equipment to evaluate relay coil conditions, contact continuity, switching behavior and electrical response. The connector can be considered for the detachable cable interface between a portable relay tester and its external relay test harness or fixture, with its five low-voltage contacts providing multiple connection paths for compatible auxiliary power, control and signal circuits. The right-angle configuration is particularly useful where the tester has limited internal space or where a straight cable exit would interfere with nearby components.

2. Key Advantages of the CBTH0BG-SMSM05-D52B
Relay testers are packed tight. The design advantages below explain why this CBTH0BG push-pull connector for railway signaling relay test equipment suits compact, detachable test interfaces:
2.1 Right-Angle Design for Compact Test Equipment
- Portable railway relay testers often contain measurement circuits, display modules, control electronics and multiple test interfaces within a relatively small enclosure. The CBTH0BG-SMSM05-D52B features an elbow-style plug design whose angled cable exit helps reduce cable routing conflicts and improves connector accessibility in compact equipment layouts.
2.2 Five Contacts for Multiple Low-Voltage Circuits
- The connector provides five low-voltage contacts, allowing equipment designers to allocate separate connections for compatible control, auxiliary power and measurement-related signals — simplifying the external test cable interface and reducing the need for several independent connectors.
2.3 Push-Pull Locking for Efficient Field Maintenance
- Railway maintenance technicians frequently connect and disconnect test leads when inspecting different relay units. The push-pull locking mechanism supports quick mating and release, helping reduce connection time during repetitive testing procedures, while its secure mechanical engagement helps prevent accidental disconnection during normal handling.
2.4 Solder Termination for Custom Test Cable Assemblies
- Solder termination allows the connector to be integrated into custom cable assemblies designed for specific relay testing equipment, so manufacturers can configure the cable wiring according to the instrument’s pin assignment, measurement architecture and external test fixture requirements.
2.5 Cable Protection and Mechanical Stability
- The CLAD52Z configuration supports a cable outside diameter of approximately 4.3–5.2 mm, and the connector’s cable collet and bend-relief arrangement secure the cable and reduce mechanical stress around the termination area — useful for portable instruments whose cables are repeatedly handled, repositioned and connected during maintenance work.
3. Why Choose the CBTH0BG-SMSM05-D52B?
For portable railway relay testing instruments, the connector interface needs to balance compact installation, convenient operation and reliable electrical connection. This CBTH0BG push-pull connector for railway signaling relay test equipment offers:
- Five low-voltage contacts for compatible multi-circuit connections.
- Right-angle cable routing for space-constrained equipment.
- Push-pull locking for quick field connection and disconnection.
- Solder termination for customised test cable assemblies.
- A cable compatibility range of approximately 4.3–5.2 mm.
- IP50 protection for suitable indoor and controlled maintenance environments.
These features make it a potential connector option for portable railway signaling relay testers, particularly where detachable test harnesses and compact cable routing are required.
