Wiring Diagrams
Connector Pin Configuration
Electrically conductive mechanical
connection (as supplied by MicroE
Systems).
INNER SHIELD:
Insulated from outer shield, sensor case, and
connector housing. Connected to circuit common
internally as supplied by MicroE Systems
OUTER SHIELD: Connected to
sensor and connector housing
Grounding Considerations
Sensor mounted with good electrical contact to well grounded surface (preferred):
Sensor mounted to poorly grounded or non-conducting surface:
NOTE: GND and INNER SHIELD ARE INTERNALLY CONNECTED.
Max cable length: 5m. Contact MicroE Applications Engineering if longer length required.

Alarm output is an open drain,
N-channel MOSFET. Drain cir-
cuit is normally closed (current
flows) and opens when the
encoder signal is too low. Alarm
requires the use of an external
pull-up resistor. See customer
supplied circuit example on right.
