Guard monitoring
Swing and sliding gates
Guard position monitoring where the incentive to bypass the switch is real and coding is the appropriate answer.
ConfirmConfirm coding level and guard geometry.
Coded safety switch
PSENcode
A guard is only as good as the difficulty of defeating it. PSENcode uses RFID coding so that a spare actuator will not fool the switch — and in the unique, fully coded version, only one single actuator is ever accepted, on the key lock principle.

Why it is specified
Coded sensing changes
The value is manipulation protection and openness — the switch resists defeat, and its standard interfaces let it drop into an existing installation.
Highest manipulation protection
The manufacturer states the highest level of manipulation protection through RFID technology, in narrow, compact or large designs.
Key lock principle
In the unique, fully coded version there is only one single actuator that the sensor accepts.
Open to other manufacturers
Integrated evaluation and standard interfaces mean PSENcode fits into an existing environment and can be used to upgrade a plant.
Diagnostics without callouts
Combined with safety device diagnostics, comprehensive diagnostic data helps avoid service callouts and reduce downtimes.
Applications
PSENcode is used
The manufacturer lists both safety gate monitoring and general position monitoring for this family.
Mounting freedom
Multiple actuation directions
High flexibility in actuation direction lets the sensor suit the door approach rather than forcing the door to suit the sensor.
ConfirmConfirm the approach direction and alignment.
Series wiring
Several guards on one input
Series connection with further sensors keeps the wiring and the controller inputs economical across a multi-guard machine.
ConfirmConfirm the number of devices in series.
Technical data
Selection parameters that matter
These are the values that decide the variant. Full specifications and dimensions belong to the selected order number in current manufacturer documentation.
Note the standard: PSENcode monitors guard position in accordance with EN 60947-5-3, which applies to non-contact devices.
| Function | Monitoring the position of guards in accordance with EN 60947-5-3, and general position monitoring |
|---|---|
| Coding technology | RFID |
| Coding versions | Coded, fully coded, and unique fully coded |
| Unique fully coded | Only one single actuator is accepted by the sensor — the key lock principle |
| Designs | Narrow, compact and large |
| Evaluation | Integrated evaluation with standard interfaces, open to products from other manufacturers |
| Series connection | With further sensors such as PSENcode, PSENslock and PSENsgate, up to PL e of EN ISO 13849-1 |
| Diagnostics | Can be combined with safety device diagnostics for comprehensive diagnostic data |
| Protection type | IP67 |
Series connection affects fault detection. The number of devices in series and the achievable performance level must be assessed together for the arrangement, not assumed from the single-device rating.
Models
Design and coding decisions
Two decisions define the order: the physical design that fits the guard, and the coding level the manipulation risk requires.

- Unique fully coded
Series
Multi-device arrangements
Series connection with PSENcode, PSENslock and PSENsgate is supported up to PL e.

Accessories
Actuators, mounting and diagnostics
The actuator and its mounting are as much a part of the specification as the sensor itself.
Actuator
Coded actuator
The actuator is matched to the coding level; in the unique fully coded version it is the only actuator the sensor will accept.
ConfirmConfirm coding level and spare-actuator policy.
Mounting
Mounting aids and brackets
Mounting accessories set the alignment between sensor and actuator and hold it over the life of the guard.
ConfirmConfirm mounting face and alignment tolerance.
Diagnostics
Safety device diagnostics
Provides device-level diagnostic data from a series arrangement rather than a single combined signal.
ConfirmConfirm the diagnostic route to the controller.
Before quotation
Application review
PSENcode is chosen when coding matters. If the guard has no realistic manipulation incentive, PSENmag may be the more economical answer.
Manipulation risk
- Whether the guard is realistically likely to be bypassed
- Why access is wanted mid-cycle, and how often
- Required coding level under EN ISO 14119
- Whether spare actuators can be controlled
Guard and mounting
- Hinged, sliding, lift-off or flap guard
- Approach direction and available mounting face
- Alignment tolerance and any door sag
- Which design — narrow, compact or large — fits
Electrical
- Number of devices and whether series connection is planned
- Existing safety controller and spare safe inputs
- Whether safety device diagnostics will be used
- Cable length and connection method
Environment and commercial
- Cleaning regime and whether IP67 is sufficient
- Temperature, vibration and contamination
- Quantity per machine and total quantity
- Whether this replaces an existing switch, and its part number

PSENcode sits in the architecture
The switch reports guard position with high manipulation resistance. If hazardous movement continues after the stop command, position monitoring alone is not enough and a locking device is required.
