Safety Switch Protects Against Equipment Tampering
Siemens' Industry Automation Division
has introduced the 3SE63 electronic
contactless safety switch for protective
equipment such as covers, flaps and
doors. Switch operation is based on contactless RFID (Radio Frequency
Identification) transponder technology
and, according to the company, offers a
high level of protection against interference, tampering or bypassing. The
switch's plastic enclosure provides protection complying with IP69K, is resistant to detergents and is designed for use
under extreme environmental conditions.
Siemens notes the 3SE63 switch satisfies regulations for tamper-proof occupational safety protection through individual coding of the switch and actuator.
The device is equipped with integrated
monitoring functions for open-circuit,
external voltage and cross-circuit, and
has two short circuit-proof 24 V DC safety outputs. Additional diagnostic functions, such as threshold indication, can
be displayed on the status LEDs on the
device or obtained from the diagnostics
output for further processing.
