Sockets & Accessories
Numerous Tyco Electronics sockets and accessories are available for
use with PTH series relays. Included among them are PC board, panel
cutout, panel and DIN rail types. Panel and DIN rail models are offered
with conventional or “finger-safe” screws, as well as screwless
terminals. Both two and four pole models are available. The PTH will fit
sockets designed for use with our PT, KHA and PCL series relays. Hold
downs designed for use with the KHA and PCL will work with the PTH.
Consult your Tyco Electronics authorized distributor or sales engineer
for details.
