in many modems, fax machines, PBX systems
and other telecommunication systems. The 1 coil
version is approved according to EN60950 and offers
sufcient distance in air and creepage paths.
• Line Sense Relay
• Approved according to EN60950
• Magnetic shield
• UL approved under E 156887 (M)
• Small size
• Washable
Part Number Example
NP-CL - 1A81 - 9 - 213
9 is the coil resistance
213 is the pin out
