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.
