Single pole spring clamp terminal blocks SM99 and SR99 offer a flexible circuit board connection solution for most industrial and building automation applications.

METZ CONNECT has developed a safe and simple single pole spring clamp terminal block specifically aimed at compact and low profile devices, and which meet today’s Safety, Reliability, & Convenience requirements perfectly.

Space optimization on Printed circuit boards is becoming more and more critical during the design process as the demand for smaller, lower profile devices increases.  As a single pole connector solution and also its compact size, SM/SR99 allows design engineers to take a flexible approach to connector placement on a PCB with the very limited space that is often available to them.  At just 6.6mm in height and 5.8mm wide SM/SR99 carries a very small PCB footprint and can be placed on the circuit board in any number of orientations.   For this innovation by METZ CONNECT, developers focused on the following market needs: integration, migration, miniaturization and reliability.

For such a compact connector, the SM/SR99 is feature rich.   Accepting solid core and stranded cables 0.2sqmm – 1.5sqmm and rated up to 9A, SM/SR99 features a unique finger operated actuator that not only allows for quick and easy wiring but also enables the operator to make multiple connect and disconnect cycles should they require.   Once the cable is inserted, the operator will find an inspection window on the top side of the housing and a quick visual check can be made.   Next to the inspection window the operator will then find a continuity test point to ensure that a quick, safe, and reliable connection has been made.   SM99/SR99, is also offered with different colour actuators for additional colour coding benefits.    The single spring clamp terminal blocks in SMT and THR versions are available in bulk packaging or on tape & reel.
