LP Series
DESCRIPTION
DIMENSIONS
All dimensions in mm [inch]
• Sealed with PU resin
• Magnetic shield
• High reliability
• Very small housing
Part Number Example
LP12 - 1A66 - 80V
12 is the nominal voltage
1A is the contact form
66 is the switch model
80 is the pin out
V is the option
The LP series of miniature Reed Relays offers the
ideal solution for high density, high frequency switch-
ing. With a coaxial shield the LP series is capable
of switching signals up to 1 GHz. Using only high
reliability Reed Switches, one is insured of long life
when switching low level signals.
