Description
Description
Guard locking switches aredesigned to provide robustposition interlock detection formoving guards and provide alock mechanism to keep theguard closed until the hazard hasbeen removed. They are tongueoperated and are designed to fitto the leading edge of sliding orhinged machine guards to providepositively operated switchingcontacts and provide a tamperresistant key mechanism that isnot easily defeatable.
Depending upon the riskassessment for the application,they can be used independentlyto provide positively operatedcontacts to EN60947-5-1 orthey can be used in combinationwith any dual channel safetymonitoring relays to provide up toPLe Category 4 to ISO13849-1 orSIL3 EN62061. They are offeredwith a choice of various actuatorsto aid installation and maintaindurability throughout the rigorousapplications of Factory Automation,Packaging, Food Processing,Pharmaceutical and Petro-Chemical Industries.
The switch is rigidly mountedto the frame of the guard ormachine. The actuator is fittedto the moving part (frame) of theguard and is aligned to the switchentry aperture. The actuatorprofile is designed to match a cammechanism within the switch headand provides a positively operatedinterlock switch. When the actuatoris inserted into the switch thesafety contacts can be closed andallow the machine start circuit tobe enabled. When the solenoidreceives the required signal thesafety contacts are positivelyopened, the machine circuit isbroken and the guard door canbe opened. They can be used incombination with safety timers toprovide a delay before allowing theguard to open (e.g. for machineswhich require run down). Standardversions automatically spring lockat the insertion of the actuatorand will only unlock when poweris applied to the solenoid. Theseswitches are sealed to NEMA 6(IP67) and provide long termprotection against moisture ingress.
