The PTSA spring-cage PCB terminal block range is characterized by an easy-to-operate angled springcage connection. It clamps solid and stranded conductors up to 0.5 or 1.5 mm2 with the pitches 2.5 and 3.5 mm. Due to the small pitches and the compact outer dimensions, this range is particularly suitable for applications in which space is critical. Typical applications include in particular lighting engineering and telecommunications. The PTSA range can be supplied as a termination block either with solder pins arranged in a row at the front, or with offset solder pins Z pinning serves to increase the voltage values up to 400 V or 630 V. Pitch spacers and different color versions make it easy to put together customized termination blocks. It is possible to intermix the pitches. Individual labeling of these products is possible.
