KACON K7SR Series Safety Relay (Forced Guide Contacts)

KACON K7SR Series Safety Relay (Forced Guide Contacts)

PCB/socket-mount safety relay with mechanically linked (forced guide) NO and NC contacts for safety circuits such as emergency stop and machine guarding.

Key features

  • Forced guide contacts to IEC 61810-3 Type A: NO and NC contacts never close simultaneously
  • 4-pole (2NO+2NC, 3NO+1NC) and 6-pole (5NO+1NC, 4NO+2NC, 3NO+3NC) versions
  • 6A 250VAC / 30VDC per circuit, AgSnO2 contacts
  • 4,000VAC between coil and contacts, 10kV surge withstand
  • Mounts on PCB or on dedicated K7SC / K7SA sockets
  • Wide -40 to +85°C operating range
