ZJA series: ZJA4 and ZJA6 force-guided relays

ZJA relays have Type A forcibly guided contacts to IEC 61810-3. Because NO and NC contacts are mechanically linked, a welded contact can be detected through its opposite contact — the basis of feedback monitoring in safety relay modules. The series comes in 4-pole (ZJA4) and 6-pole (ZJA6) versions with the same 40 × 13 × 24 mm PCB footprint.

How the model number is built

ZJA4 or ZJA6 / coil voltage — arrangement code, then T for AgSnO₂ contacts and R for gold-plated contacts. Example: ZJA6/24—4H2DT is a ZJA6 with a 24 V DC coil, 4NO+2NC and AgSnO₂ contacts. Coils: 5, 6, 9, 12, 18, 24, 36, 48 and 110 V DC.

  • Contact rating 6 A 250 V AC / 30 V DC (resistive)
  • 10 kV surge input–output, 4000 V AC coil–contacts
  • CE, TÜV Rheinland, cULus; UL Class F insulation; RoHS

For DIN-rail use, ZJA relays fit A4/A6 push-in and A4/A6 screw safety relay sockets, plus the A6 push-in and screw-type sockets. Back to force-guided relays.
