The compact 'all in one' safety switch with a safe output
The 171K series from elobau makes machine safety simple. This magnetic safety switch is ETL approved, and ideal for applications on small OEM machines or standalone equipment with a single point safety requirement, it removes the need for a safety switch and a separate safety relay. The device, which is believed to be unique on the market, utilizes a standard M30 body.
Available in 2 operating versions - front actuation, which requires the magnet approaching to the front of the device (as shown in the illustration), and lateral actuation, where the magnet approaches to the side of the device. Selection of the appropriate magnet provides a reliable switching distance of up to 21 mm.
Available for operation on 230 vac or 24 vdc with a 2.5 amp rated safe output contact. As shown in the circuit diagram, the 6 wire device has 2 wires for the power supply; 2 wires for the safe output; and 2 wires for the control output. The switch is fitted with a diagnostic LED indicator as standard, and is suitable for use up to PLd/SIL CL3/Cat3.
Protection to IP67 and an operating temperature range of -25 to +75degC means the switch copes easily with harsh industrial environments.
