REER ASE618P Light Curtain Emitter Espe Type 2

The REER ASE618P light curtain emitter is a 24 VDC electro-sensitive protective device (ESPE) Type 2 that forms the active half of a REER safety light curtain when paired with a compatible receiver. It features four optical beams and a 172 mm lens pitch to establish a guarded field across an access point, with a 3NC wiring configuration for connection to the control system. The variant is identified as ASE618P with part number 8011020, designed to operate from a 24 V DC supply and to integrate into ESPE Type 2 safety circuits that meet relevant performance standards. Typical applications include safeguarding around automated machinery such as presses, cutters, winders, and conveyors, where unintentional human entry could pose a risk of injury. Some supplier listings note that ASE-618/ASE618P models have been discontinued by the manufacturer, which can impact availability and replacement planning; verification with distributors is recommended if continuity or support is important. As part of a complete safety system, this emitter is used in conjunction with a matching REER receiver to create a complete ESPE barrier, aligning with IEC 61496 Type 2 safety requirements and enabling prompt stop of hazardous motion when the guarded zone is breached.
