Optical arrangement and infrared safety principles of WGM43 light curtains

Industrial optoelectronic safety light curtains across the WEISHIDQ WGM43 line deliver dependable active guarding for operators of mechanical, hydraulic, and coining presses.

The system consists of an optical emitter and receiver pair producing 10 synchronized parallel infrared beams across a 40 mm pitch, guarding a 360 mm active vertical window. An onboard microprocessor continuously verifies channel health and suppresses false trips from ambient plant illumination.

If an operator breaches the optical boundary, electromechanical relay contacts or solid-state outputs disconnect machine drive circuits in less than 20 milliseconds.

Safe mounting distance calculations and WGM27 integration on machine tools

Multi-beam optical barriers in the WEISHIDQ WGM27 series feature 6 optical axes to protect hazardous zones around guillotine shears, press brakes, and automated stamping cells.

Emitter and receiver brackets are positioned in compliance with standard safety distance guidelines calculated from tool velocity and total machine stopping time.

The extruded aluminum alloy housing withstands heavy mechanical vibrations and mounts firmly to equipment beds through adjustable brackets. The protective output with changeover contacts connects directly into emergency stop lines without rewiring main electrical cabinets.

Installation of compact WGM18 safety curtains in confined tooling zones

Compact infrared safety curtains across the WEISHIDQ WGM18 line are engineered for installation within restricted spaces of assembly conveyors, coining stations, and compact tooling beds.

With an overall body length of 180 millimeters, the optical barrier shields the part feeding envelope with four infrared beams without obstructing operators or adjacent tooling. The internal electronic filtering module eliminates electrical interference generated by variable frequency motor drives.

The responsive NPN NC transistor output provides rapid fault signals directly into programmable automation controllers.

High-resolution finger detection and optical alignment on WGM20 light grids

High-resolution safety grids in the WEISHIDQ WGM20 line are specifically developed for finger and hand protection near dangerous mechanical pinch points. The narrow 20 mm pitch between adjacent beams senses slim objects and delivers exceptional operator protection close to moving tooling.

Multi-color alignment LEDs positioned on terminal caps indicate mutual optical beam alignment in real time during setup. This feature accelerates recommissioning following tool changeovers and prevents machine cycling if optical axes become misaligned during operation.

Setting up U-frame slot optical sensors for moving web edge and mark reading

Optoelectronic slot sensors from WEISHIDQ featuring a rigid U-shaped profile provide high-speed part positioning, web edge tracking, and color register mark reading on moving materials.

The integrated one-piece body with fixed emitter and receiver spacing requires no optical re-alignment and resists industrial plant vibrations.

The electronic receiver stage achieves switching frequencies reaching 5 kilohertz, tracking register marks on rapid packaging, slitting, and labeling equipment. The rugged polymer housing with metal mounting sleeves secures firm placement on guide rods.

Operation of M12 through M30 inductive proximity switches on machine slides

Cylindrical and rectangular inductive proximity switches from WEISHIDQ provide precise end-position sensing for metal slides, rotary index tables, and tool turrets on metalworking machinery.

The nickel-plated metal enclosure with IP67 protection prevents penetration of synthetic coolants, cutting oils, and metal chips into internal electronics. Sensors operate reliably across a 10 to 30 VDC supply window and feature internal short-circuit protection against wiring errors.

A wraparound LED indicator on the rear face gives clear visual status whenever a target approaches.
