Connection
Cables and connectors
Cable, connector and adapter accessories are selected with the switch, based on the run length and the connection method at the controller.

Safe hinge switch
PSENhinge
Guard monitoring built into the hinge itself. Because the switch sits at the pivot and is concealed within the guard, there is no exposed actuator on the leading edge to align, damage or defeat — while the switching point remains adjustable anywhere from 0° to 270°.

Why it is specified
Effect of the hinge-mounted approach
The advantages come directly from where the switch sits, not from generic product claims.
Concealed installation
Mounted within the guard, so there is no visible switch or actuator inviting manipulation.
Adjustable switching point
Set anywhere from 0° to 270° and re-adjustable, so the trip angle suits the guard rather than the reverse.
Hinge and switch in one
Supplied as a complete solution, removing the separate alignment of a switch and actuator pair.
IP67 for washdown
Rated for heavy soiling and hygiene-critical areas where exposed switches struggle.
Applications
PSENhinge is used
The manufacturer lists packaging technology, the pharmaceutical industry and the food industry among its typical industry uses.
01
Hinged guard doors
Rotatable and hinged gates where the monitoring point is better placed at the pivot than on the closing edge.
02
Lift-up flaps and covers
Flaps and covers that open through a wide arc, where a conventional actuator would disengage early or bind.
03
Washdown environments
Food and pharmaceutical machinery cleaned regularly, where IP67 and a concealed installation both matter.
04
Guards prone to tampering
Access points where an exposed switch has previously been bypassed with a spare actuator.
Technical data
Selection parameters that matter
The values below are the ones that decide whether PSENhinge suits a given guard. Complete specifications, approvals and dimensions belong to the selected order number in current manufacturer documentation.
Note the performance level condition: PL e of EN ISO 13849-1 and SIL CL 3 of EN/IEC 62061 apply when two switches are used.
| Function | Monitoring the position of movable guards in accordance with EN 60947-5-3 |
|---|---|
| Performance level | Up to PL e of EN ISO 13849-1 if two switches are used |
| Safety integrity level | Up to SIL CL 3 of EN/IEC 62061 if two switches are used |
| Switching point | Freely settable from 0° to 270°, and re-adjustable |
| Contacts | 2 NC |
| Protection type | IP67 |
| Housing | Plastic-bodied design |
| Mounting | Systems can be attached on the right and on the left |
| Controller pairing | Can be used with controllers for applications with high safety requirements |
| Guard types | Rotatable and hinged gates, and flaps |
A single switch does not by itself establish PL e. The achievable performance level follows from the complete safety function, including the evaluation, the output stage and the machine response.
Models
Handing and installation variants
The range allows the hinge switch to be fitted to either side of the guard. Confirm the exact order number against current manufacturer data for the guard in question.
Handing
Right and left
Systems can be attached to the right and left, so the guard swing direction does not dictate a different product family.
- Contacts
- 2 NC
- Protection
- IP67
Adjustment
Switching point set on site
The trip angle is set during installation and can be re-adjusted later if the guard or the process changes.
- Range
- 0°–270°
- Re-adjust
- Yes
Accessories
Connection technology and pairing
The manufacturer lists the required cable, connector and adapter accessories under connection technology for this family.
Evaluation
safety controllers
The switch provides the guard signal; a safety relay or configurable controller performs the safe evaluation and drives the output stage.
Typical pairingPNOZ relay or PNOZmulti 2.
Series wiring
Multiple guards
Where several guards are wired in series, the effect on fault detection and on the achievable performance level must be assessed for the arrangement.
ConfirmNumber of guards and the evaluation route.
Before quotation
Application review
PSENhinge is a mechanical fit as much as an electrical one. These points determine whether it suits the guard and which variant is required.
Guard and mounting
- Hinged, rotatable or flap-type guard, and its weight
- Swing direction and whether right or left handing is needed
- Available hinge positions and existing hinge arrangement
- Required trip angle within the 0°–270° range
Safety function
- The hazard the guard protects, and the machine run-down time
- Whether guard locking is required rather than monitoring alone
- Target performance level, and whether two switches are intended
- Existing safety relay or controller and spare safe inputs
Environment
- Washdown, cleaning chemicals and hygiene requirements
- Soiling, temperature and vibration at the hinge
- Whether IP67 is sufficient for the cleaning regime
- Any food-contact or pharmaceutical constraints
Commercial
- Quantity per machine and total quantity
- Cable length and connection method
- Whether this replaces an existing switch, and its part number
- Required delivery timeline

PSENhinge sits in the architecture
The hinge switch reports guard position. If the hazard continues after the stop command, position monitoring alone is not sufficient and a locking device is required instead.
