40. FTR-P1 Series (p.254-259) 1
s
FEATURES
q
Original construction, where reduction of operational
noise is considered when mounted on PCB, made it
possible to design this quiet relay.
(Average acoustic noise level: 53 dB, distance 10 cm)
q
New types of materials are used for the conductive parts,
allowing this compact relay to carry 20 AMP.
q
Two types of contact material are available for various con-
tact loads.
q
Wider contact gap (0.6 mm) version is also available for
enhanced cut-off ability to overload condition.
