Mechan Controls developed the electronic non-contact safety switch in 1973. The F-SERIES, is the latest version of this product, which now has a record of more than 30 YEARS proven safety and reliability.
 
The F-SERIES is a uniquely flexible DIN rail mounting safety control unit designed for monitoring up to 30 Mechan safety switches.
 
The main control module (FM1) contains the power supply, dual safety contacts and a monitoring circuit for easy integration into your control circuits along with the input and indication for one safety switch.
 
The extender modules provide inputs for 1 (FX1) or 2 (FX2) Mechan safety switches and provide both LED and volt free contact indication from each of the safety switches enabling fast, easy diagnosis of open gates or faults.
 
Mechan safety switches are available in a variety of sizes to suit all applications. They are tamper-proof, i.e. only a Mechan actuator will operate the system, and with an 8-1Omm switching distance, they are easy to install, tolerant to misalignment and guard wear. Designed to withstand the harshest environments, the electronic switching is encapsulated into an ABS housing making the Mechan safety switches immune to water, hot hosing, dust or oil etc.

When the safety switch actuator is brought within the operating range of the sensor (8-10mm target to target), a signal is generated and transmitted to the safety control unit The control unit evaluates this signal and if all monitored gates are closed and the control module's internal self-check is completed, the Mechan safety contacts will close.
