Make connections in less time, with more safety
and reliability:
The new spring clamp terminal blocks SM99/SR99

The single terminal blocks SM99 and SR99 both have a very compact design and accept wire cross sections up to 16 AWG. With the push-in technique for wire insertion and a large finger push-button for wire release, these terminal blocks deliver optimum ease of use. In addition they feature a high level of connection reliability with their wire connection indicator and a test point for a continuity check. The reflow-capable and tape & reel packaged single terminal blocks offer maximum flexibility for the PC board design as they can be placed as single poles nearly everywhere on the PC board. This means that the SM99 and SR99 terminal blocks are suitable for any PCB mount wire to board applications in consumer, lighting, HVAC, security and industrial markets.
