SP99 – the perfect Spring Clamp Terminal Block for DIN Rail devices:

The latest addition from METZ CONNECT to its range of pluggable terminal block solutions designed for Industrial and Building Automation DIN Rail mount devices - SP99. This Spring clamp connector features 2 individual cable entry points per pole accommodating up 2 x 2.5sqmm conductors. Push-in technology for rapid wire installations and maintenance free connections.

Pluggable spring clamp terminal blocks for DIN rail-mounted devices in the manufacturing sector

Rail-mounted devices in industrial automation: These days process flows in the manufacturing sector often use controllers which for the most part are devices that mount on to DIN rail. These configurable control systems are designed to carry out multiple safety or monitoring measurements at machine or system level. Often the controls allow a modular upgrade so that they can be adjusted to the requirements and the size of the machine. This requires a modular connectivity that METZ CONNECT is comprehensively covering with its U-Contact range of PCB level connectors.

Connection technology for rail-mounted devices used in the manufacturing sector has changed: For decades screw type terminal blocks have been the connection technology of choice for rail-mounted devices used in building and industrial automation applications. Nowadays, in pursuit of improved contact security, reliability, and connection friendliness, device manufacturers are now moving towards spring clamp technology connectors.

The push-in technology of these connectors is extremely user-friendly offering a fast and tool-free cable connection. Installer experience in the field has shown that wiring installation times can be reduced by up to 50 % when using Spring connectors with Push-in Technology in comparison to the traditional screw-type technology. Furthermore, the Spring clamp technology offers permanent contact security to the conductor particularly in environments where vibration is present. The solution: The SP99 by METZ CONNECT.

SP99 – the perfect spring clamp terminal block for rail-mounted devices: Besides the general benefits of this terminal block such as contact security (maintenance free connection), permanent conductor contact, rapid connection by push-in technology, SP99 offers additional benefits for the manufacturing sector: Industrial automation often needs to connect an electrical potential to process signals. And the SP99 is offering two potential connections per pole with a diameter of max. 2 x 2.5 mm².

Downtimes in a manufacturing system are expensive, therefore a quick fix should be provided when a malfunction occurs. For a general prevention of shortfalls a systematic check of the different sectors of the system is necessary. Ideally each wire can be released separately at the rail-mounted device. The SP99 allows for separate release of each wire with a push-button actuator for each cable entry and the 90 degree wire entry angle guarantee a user-friendly experience. SP99 is a pluggable solution and therefore ideally suited for multiple quick connect and dis-connect cycles.

To avoid mis-aligned connections and ultimately device or system damage, METZ CONNECT offers additional mechanical coding options for SP99: coding pins are inserted into the respective notches of the terminal block and the respective pin header to guarantee correct connections are made every time.
