PROXIMITY SWITCHES
The inductive type proximity switch provides end of rotation
indication. The non-contact probe senses the presence of
the ferrous cushion spear and has no springs, plungers,
cams or dynamic seals that can wear out or go out of
adjustment. The switch is solid state and meets NEMA 1, 12
& 13 specifications. For ease of wiring the connector housing
is rotatable through 360°. To rotate, lift the cover latch,
position, and release.
The standard proximity switch controls 20-230 VAC/DC loads
from 5 to 500 mA. The low 1.7 mA off-state leakage current
can allow use for direct PLC input. The standard short circuit
protection (SCP) protects the switch from a short in the load
or line upon sensing such a condition (5 amp or greater
current) by assuming a nonconductive mode. The fault
condition must be corrected and the power removed to reset
the switch preventing automatic restarts.
The low voltage DC switch is also available for use with 10-
30 VDC. This switch is in a non-rotatable housing, but does
incorporate the short circuit protection.
Both switches are equipped with two LEDs, "Ready" and
"Target". The "Ready" LED is lit when power is applied and
the cushion spear is not present. The "Target" LED will light
and the "Ready" LED will go out when the switch is closed,
indicating the presence of the cushion spear. Both LEDs
flashing indicates a short circuit condition.
NOTES:
1. Available with or without cushions.
2. Not available with stroke adjusters.
3. Pressure rating: 3000 psi
4. Operating temperature: -4°F to 158°F
5. Specify switch type, orientation and voltage when ordering.
6. The low voltage DC switch is available in non-rotatable style
only; consult representative for further information.
