General data for all models RI-27
AT-Customization / Preformed Leads
Besides the standard models, customized products can
also be supplied offering the following options:
! Operate and release ranges to customer specification
! Cropped and/or preformed leads
Coils
All characteristics are measured using the Philips
Standard Coil. For definitions of the Philips Standard
Coil, refer to the Reed Switch Technical & Application
Information Section of this catalog.
Life expectancy and reliability
The life expectancy data given below are valid for a coil
energized at 1.25 times the published maximum operate
value for each type in the RI-27 series.
No-load conditions (operating frequency: 100 Hz)
Life expectancy: min. 10

RI-27 Series
Pico dry-reed switch hermetically sealed in a gas-filled glass envelope.
Single-pole, single-throw (SPST) type, having normally open con-
tacts, and containing two magnetically actuated reeds.
The switch is of the double-ended type and may be actuated by an
electromagnet, a permanent magnet or a combination of both.
The device is intended for use in relays, sensors, pulse counters or
similar devices.
