HH52P HH53P HH54P HH62P HH63P HH64P Miniature Control Relays Bulk Pack AC12V DC24V AC220V Small Intermediate Power Relay Module

HH52P / HH53P / HH54P / HH62P / HH63P / HH64P Miniature Intermediate Control Relays

The HH52/53/54 and HH62/63/64 series are industry-standard miniature general-purpose intermediate relays, widely used in PLC control panels, industrial automation systems, HVAC controllers, and electrical distribution boards worldwide. Built with polycarbonate dust-proof enclosures and silver alloy contacts, these relays deliver reliable switching performance across millions of operations.

Available in AC 12V, DC 24V, and AC 220V coil voltages, with 2PDT, 3PDT, and 4PDT contact configurations, this listing covers the full HH series range in bulk packs of 10 units — ideal for panel builders, OEM manufacturers, and maintenance stock.
