SI-LS42DMJ, Banner

Turck SI-LS42 Series Safety Interlocking Switches The SI-LS42 series safety interlocking switches come with guard locking capability. This makes it possible for them to be used to secure a guard (or gate) such that the hazard has time to stop before the guard can be opened. As such the guard can be located closer to the hazard making access to the hazard for maintenance easier yet still maintaining the safety of the operator. Positive opening safety contacts Choice of two locking mechanism types: Spring lock (energized solenoid release) or energized solenoid lock (spring unlock) Models with spring lock/solenoid unlock have a manual release Two solenoid voltages available: 24V ac/dc or 110V/230V ac Actuator head rotatable in 90° increments Actuator can be positioned either horizontal or vertical Environmental rating; IP67 Operating temperature range: -25 to +70 °C Interlock Switch

3SE5312-0SE11, Siemens

3SE5 Series, Auxiliary Release The SIRIUS 3SE5 solenoid interlock switch with separate actuator and additional electromagnetic tumbler is designed for protective doors that have to remain closed while a machine is being shut down. An integrated auxiliary magnet in the switch keeps the door locked until a specific signal has been received. A safety mechanism to prevent unwanted closing ensures that the NC contacts of the magnet never close even when the door is open. The switch can be released manually using an auxiliary release mechanism if, for example, access is required following a power failure or during installation. Some of the outstanding standard features include an integrated solenoid interlocking with 24 V, 115 V or 230 V coil voltage, 6 switching contacts and separate position sensing for the magnet and the protective door. Optical status monitoring is also available. Higher locking forces (2600 N on the metal version, 1300 N on the plastic versions) guarantee enhanced safety even in harsh industrial environments 2 x 3 contact blocks are included as standard, 2 NC contacts and 1 NO contact are provided for magnet and actuator monitoring The new, innovative ASIsafe solution with integrated module, which has been designed with safety in mind, greatly reduces the load on the data line: contact monitoring and magnet control draw on ≤170 mA A number of additional release mechanisms to handle any application: auxiliary release mechanism, lock release, escape release and emergency release Actuator heads can be rotated in 4 x 90° increments; 5 directions of approach (4 x lateral + 1 x front) LED status display IP66/67 protection Protection up to Cat 4 (EN 954-1), Up to SIL 3 IEC 62061 Note Actuators must be purchased separately

450301, IDEM

IDEM RAMZLOCK KLTM Solenoid Interlock Switch with Unique RFID Coding The RAMZLOCK KLTM-RFID series from IDEM are solenoid locking door switches with traditional mechanical anti-tamper tongue technology (CAM system) but which also incorporate uniquely coded RFID non contact sensor technology. These switches are ideal for preventing accidental or deliberate attempts to by-pass the interlock offering dual protection as both technologies must be satisfied to enable the machine to be started. Depending upon the risk assessment for the application, the RAMZLOCK can be used independently to provide positively operated contacts to IEC 60947-5-1 or can be used in combination with any dual channel safety monitoring relays to provide up to Category 4 PLe ISO 13849-1 or SIL3 EN62061. These RFID switches have a red painted diecast body and stainless steel head and have been developed with a holding force of 2000N to keep medium to large guard doors closed until hazards have been removed. They have a low profile and fixing holes are on an industry standard 73mm centre to enable easy retro fitting to new or existing guards. The KLTM-RFID safety switches fit to the leading edge of sliding or hinged machine guards and have been designed for use in the Factory Automation, Packaging, Food Processing, Pharmaceutical and Petro-Chemical industries. Integral high security RFID coding RFID antenna on front and end entries High holding force 2000N Spring to lock when actuator is inserted - energise solenoid to unlock 2 lock monitoring safety contacts for high function and diagnostic specification Auxiliary PNP outputs for switch status LED diagnostics for solenoid, lock and RFID 2 emergency manual release points Positive break contacts to IEC 60947-5-1 High functional safety to ISO 13849-1 Connects to most safety relays to give up to PLe Cat.4 IP67 protection 3 conduit entry points M20 Rugged red painted diecast body and stainless steel head Will fit on 73mm fixing centres 2 actuator e...

440G-T27132, Allen Bradley Guardmaster

TLS-GD2 Solenoid Interlock Switch, for Demanding Applications Features & Benefits Note The TLS-GD2 is a positive mode, tongue operated guard locking interlock switch that locks a machine guard closed until power is isolated and ensures that it remains isolated while the guard is open. The switch has three safety (N.C.) contacts and two auxiliary (N.O.) contacts. The head of this interlock switch has two entry slots and it can be rotated to provide four actuator entry points. A blanking plug is provided to seat the unused slot. The guard may only be opened when a signal is applied to the TLS-GD2 internal solenoid which releases the lock mechanism. Therefore this solenoid interlock switch is ideal for machines which do not stop immediately or where premature interruption of the machine could cause damage to tooling and components or cause an additional hazard. The safety switch is available in three types. The TLS-1 GD2 and TLS-3 GD2 incorporate a power-to-release function. Two manual release points with security screws allow the locked TLS-GD2 to be released in emergencies. An optional lid-mounted key-release style can also be supplied. The TLS-2 GD2 has a power-to-lock function. Each type of switch has five sets of contacts of various forms and are suitable for use with PLCs. The TLS-1 GD2 and TLS-3 GD2 are both available with escape release options. They are intended for machine guarding with full body access. The switch is installed so that the escape release push button on the rear side is accessible from inside the hazardous area. This allows the intentional unlocking of the TLS-GD2 from inside a hazardous area, providing a means of escape for a person who may become trapped. A stainless-steel actuator guide is fitted to protect the switch from actuator damage due to poor guard alignment or guard wear. TLS-GD2 has an ingress protection rating ...
