ZL & ZR Slimline proLok - Solenoid Controlled Switch Body

Slimline proLok - Solenoid Controlled Switch Body is used to manage activities by means of a solenoid control element. 

NOTE! There are 2 derivatives, Normal and Releasing. The Releasing version is the type that MUST be used if used in conjunction with any type of internal release function (for example a pro Push IR module).

Fully Monitored Solenoid (Power to Lock & Power to Unlock) - ZL411, ZR411, ZL471, ZR471

Un-monitored Solenoid (Power to Lock & Power to Unlock) - ZL461, ZR461, ZL416, ZR416

Slimline proLOK - Standard (Power-to-Unlock, Fully Monitored Solenoid)
On supplying power to the solenoid, the unit becomes unlocked, the Safety Circuits will open and the Monitoring Circuit will close. This is the recommended set up for most machine guarding applications. A special key driven override facility is included to unlock the unit in the event of a power failure.
• LED indicators for status identification.
• To be used with a safety relay and/or safety PLC control systems.
• Ideal for machines with run-down cycles.

Slimline proLOK - Power-to-Lock (Fully Monitored Solenoid)
On supplying power to the solenoid, the unit becomes locked, the Safety Circuits will close and the Monitoring Circuit will open. This is not the recommended set up for most machine guarding applications - however, it allows faster access and exit in the event of a power failure.
• LED indicators for status identification.
• To be used with a safety relay and/or safety PLC control systems.

Slimline proLOK - Un-Monitored Solenoid (Power-to-Unlock)
On supplying power to the solenoid, the unit becomes unlocked, however only the Monitoring Circuit will close. These units have no Safety Monitoring on the Solenoid action. This is a popular configuration for applications where the solenoid performs a process control rather than a safety function. A special key driven override facility is included to unlock the unit in the event of a power failure.
• LED indicators for status identification.
• To be used with a safety relay and/or safety PLC control systems.
