Description
The JSNY9 is used for locking a gate/hatch, to prevent access to machinery, until hazardous operations have ceased. Applications include:
- Processes which cannot be interrupted, e.g. welding.
- Machinery with a long stopping time, e.g. paper machinery which requires a long braking operation.
- Prevention of unauthorized access to a particular area.
The JSNY9 is equipped with a 2 x (1NO +1 NC) contact configuration, the first pair of contacts changeover when the key is inserted. The second pair of contacts changeover when the locking mechanism is in the locked position.
The JSNY9 switch is encased in a robust plastic housing and can be mounted either horizontally or vertically. The advanced design of the head provides eight possible key insertion options, this is achieved by mounting the head either vertically or horizontally on the base unit, as shown in the diagram. The location for the actuator key is reinforced and bevelled to ensure a smooth operation.
The control unit offers eight operating positions that provide the actuator with eight different input options.
Protection from Unauthorized or Incidental Access
The JSNY9 is designed to protect against unauthorized access; screwdrivers, magnets or similar tools cannot manipulate the safety switch.

Two Versions
The JSNY9 switch is available in two basic versions, either with a spring lock or an electromagnetic locking mechanism.
The JSNY9S (spring lock) switch operates immediately when the gate/hatch is closed, i.e. when the key actuator is inserted into the locking mechanism. The gate/hatch can be opened and the actuator key released only by supplying the operational voltage to the solenoid connections (E1 E2). The JSNY9S also has a manual emergency unlocking facility to enable authorized release of the actuator key.
In the JSNY9M (magnetic lock) version, the mechanism is only locked when the gate/hatch is closed i.e. the actuator key inserted and the solenoid (E1 E2) supplied with the operating voltage. The gate/hatch can only be opened when this operating voltage is removed.
Safety Level
In order to achieve a high safety level, the JSNY9 switch is equipped with dual sets of contacts operated with a coded actuator key. In order to meet the required installation safety level it is recommended that the JSNY9 safety switch is monitored by an appropriate JOKAB SAFETY safety relay.
Regulations and Standards
The JSNY9 is designed and approved in accordance with appropriate standards. Examples of such are: EN60204, IEC 204, EN 60947-5-1, IEC 947-5-1, VDE 0113, VDE 0660 T200, GS-ET 19 and EN 1088.
