-Prewiring: The PI basic terminal block can be installed and wired in the control cabinet without pluggable electronics. The required electronic components are plugged in later. They are coded automatically and snapped securely.
-Functional adaptations are an easy matter during the startup phase.
-There is no need to remove the Ex-I conductors in order to replace a module or alter a function.
-Reserves are simple to retain. Only the PI modules that are actually required at startup time are plugged in.

Application:
Optoelectronic safety device are used as entry, danger point or danger zone guards.
SLB range safety light barriers ar utilised as entry guards to dangerous areas. these protection devices operating without physical contact achieve Control Category 2 or 4 to EN 954-1 in combination with SLB 200-C or SLB 400-C safety monitoring modules.
Design and mode of operation:
On the SLB/SLC/SLG ranges of optoelectronic safety devices, the emitter and receiver are fitted in two separate enclosures. An invisible infra-red signal is sent from the emitter and this is picked up by the lens system of the receiver and evaluated either by an integral or external safety monitoring module. If the light beam is interrupted, the secure outputs are switched.
All of the optoelectronic safety devices listed here are maintenance-free and are characterised by simple fitting and adjustment.

SICK's single-beam photoelectric safety switches consist either of testable senders and receivers, or of testable senders and receivers combined with an evaluation unit. These devices impress both with their large scanning range and the variety of shapes and sizes available. They also offer maximum safety performance as they comply with type 2 or type 4 in accordance with EN 61496 and PL c or PL e according to EN ISO 13849. The possible applications are very wide-ranging: Whether on robots, processing machines, machining centres, palletising systems, high-bay warehouses or transfer lines - with products from SICK you will profit from a customer-friendly solution of the highest quality.

Safe4 light curtain is a contactless safety device with built-in self-testing. It contains two redundant self-monitored chan nels which fulfill index IV of the Machine Directive EC/98/37 as cat. 4 safety light curtains and IEC / EN 61496.
The light curtain system is very resistant to ambient light interference and can cope easily and very reliably with demanding applications, such as welding robots. The large detection range (up to 30 m for hand-resolution and up to 9 m for finger-resolution) also enables the reliable safeguarding of hazardous zones covering large areas. With Safe4 units available starting at 120 mm lengths, they are optimally designed to safeguard small hazardous areas.In addition, it is also possible to combine multiple protective fields (cascading or L-configuration), and monitor them with a single controller. This provides the machine manufacturer the freedom to optimize the machine design.
