Traffic Cabinet Relays

21H Series
Flash Transfer Relay for Next Generation of ATC Traffic Light Cabinets

The new Hermetically Sealed 21H relay is a sealed rugged design for years of use in the field. Designed more compact with superior reliability for the new ATC cabinets.

Features:

The 21H is sealed with a dry nitrogen gas to keep out moisture, dirt, ants or other outside contaminations that could get between the contacts and cause failures. This insures increased stability and life of the contacts.
Contacts rated to 10 Amps @ 48VDC or 120VAC.
LED indicator is wired to show actual transfer of the contacts not just that the power is applied to the coil.
Rugged plug pins will withstand field installation if necessary.
Sockets available - Panel Mount (SK-TRF-MW) or PCB (SK-TRF-MP).

21/136 Series
Flash Transfer Special Purpose Relays

The 21 and 136 series flash transfer relays have a proven industry record of reliability. Their rugged design has allowed the products to be plugged in and left, for years of service. Recent changes in lighting techniques from incandescent to LED have prompted us to respond with a redesigned relay better suited for the low currents of LED lighting, but equally usable with tungsten lamps.

Additional contact configurations and coil options are available
