The pitch determined for each of the series SY piping ports (P, A,
B, etc.) is based on the assumption that series KJ one-touch
fittings will be used. For this reason, other pipe fittings may
interfere with each other depending on their type and size.
Dimensions should be confirmed in a pipe fitting catalog before
they are used.

Select a SMC connector cable (V100-49-1-„) or a FA sensor
type connector, with M8 threaded 3 pin specifications
conforming to Nippon Electric Control Equipment Association
Standard, NECA4202 (IEC60947-5-2). Make sure the
