GATE GARD® Solid State Interlock Switches
and Cable Pull Switches
9007 GATE GARD Solid State Interlock Switches
For non-contact gate or guard interlocking
The 9007 SG GATE GARD solid state interlock switches are designed to verify that gates or guards are closed before a machine is allowed to start. It is a solid state self contained switch that detects the signature of its mating actuating key. The actuating key can approach from almost any angle. Alignment between switch and actuating key is non-critical, and allows up to a 0.25 inch gap between them.
Three LEDs (power, fault, load) indicate the switch's status. Protective internal circuitry will lock the switch off under certain fault conditions, causing the fault LED to begin flashing. When the fault LED is flashing, power must be reset to restore normal operation.
An optional power supply is available to provide 24 Vdc to up to three 9007 SG units and also provides a 5 A relay output when all guards are closed.
Features and Benefits
 |
Short circuit, reverse polarity and overload protection
|
|
No contact between switch and actuating key
|
|
Tolerates gate and guard alignment problems
|
|
Alignment arrows and pre-wired construction allows for easy installation
|
|
Actuating key can approach from almost any angle
|
|
Difficult to defeat, switch will go into fault detection mode if improper actuator is detected
|
|
Operates on 10 to 30 Vdc, and provides .5 A solid state output

Cable Pull Switches
For emergency stop operation
XY2 cable pull switches provide for emergency stop signaling at any point along a cable up to 165 feet in length. This is preferable to installing many individual emergency stop push button stations along a conveyor or around the machine, providing a more cost effective solution. Typical applications include conveyor systems, packaging, textiles, transfer machines, presses, woodworking equipment and paint lines.
Operation is based on the taut cable principle. The cable must be tight and have appropriate tension applied to set or reset the switch. Once cable tension has been set, the device will open the N.C. control contacts if either the cable is pulled or if it becomes slack due to stretching or breakage of the cable. Normal stop versions are used where a momentary, non-emergency signal is required at any point along a cable.
Features and Benefits
|
Cable lengths: XY2CE 165 feet and XY2CH 50 feet
|
|
Emergency stop versions (available in XY2CE and XY2CH)
|
| |
— |
The N.C. contact opens the control circuit and mechanically latches, and will remain latched in the open position until an operator manually resets it
|
| |
— |
Emergency stop versions have positive/direct opening contacts as standard
|
| |
— |
Device will not reset if out of adjustment
|
|
Normal stop versions (available in XY2CE and XY2CH)
|
| |
— |
Normal stop versions are used where a momentary,
non-emergency signal is required
|
| |
— |
Normal stop versions do not latch contacts open or include positive opening contacts
|
| |
— |
Normal stop versions are provided with snap action contacts for momentary stop
|
