Note: Use of a protection circuit is recommended when connecting an inductive load (for example, connecting a
relay or an electromagnetic valve, etc.).
REED SWITCH SENSORS
(Not compatible with TTL level logic.)
Reed switches provide the following features:
• NO (Normally Open) or NC (Normally Closed)
• Fully adjustable travel
• Mechanical reed
• LED Indicator
• 5-24VDC or 85-150VAC
1
• Low Amp. and High Amp.
• Senses magnet on screw carrier
• Lowest cost
• Medium life
Reed switches are available in a normally open or closed configuration.
The low amp switch is suitable for connection to PLCs or other
low current devices. The high amp switch can be used to drive
sequences, relays. coils, or other devices directly. Not compatible
with TTL level logic.

Polarity is restricted or DC operation (+) to Brown, (-) to Blue. If reversed (for TTL level compatibility), contacts will close but LED will not
illuminate.
