Mechan Controls - HE4-21-DC-06M, Coded Magnetic Safety Switch and Actuator, 2NO/1NC, DC, Plastic, 6m pre-wired Cable

Mechan Controls safety switches of HE series are magnetically coded, solid state non-contact making them easy to install and tolerant to misalignment brilliant for use in machine guarding applications. Solid state makes them more tolerant to shock and vibration and provides single point switching which makes reliable, simple machine guard interlock. HE safety switches are able to connect to the SCU-1 Safety Control Unit making it possible to have up to 30 switches.

Operation

The HE series safety switches have up to 2NO and 1NC solid state outputs along with built in LED.When installed on a machine guard, power is applied, and the switch and actuator are within the specified operating range, the N/O Outputs will be closed, the N/C Output will be open. The actuator can approach the switch from any angle without false tripping. When the guard is closed, the targets on the printed face of the switch and actuator must be aligned.

How does Mechan describe the contact configuration? (IMPORTANT)

Mechan Controls describe the state of the safety contacts as N/O (normally open) and the auxiliary contact as N/C (normally closed) when the door is open and not within operating distance.

Volt Free Outputs

Volt free contacts are invariable mechanical contacts. In order to form a safety circuit, connection to monitored safety inputs is required.

Tolerant to Temperatures

Standard -25°C to 55°C.
