Euchner STA3A-2131A024M Euchner Safety Switches and Guard Locking Systems

Razz Middle East supplies Euchner machine safety components in Saudi Arabia, sourced to order and delivered duty-paid to site. The range covers coded safety switches, guard locking systems, position switches and hand-held enabling switches for machine guarding. Part numbers carry a six-digit order code, such as MGB-L1HE-ARA-R-105784, and that code is what a quotation is built from.

This page covers Euchner part number STA3A-2131A024M — Euchner Safety Switches and Guard Locking Systems. Quote the full part number with your enquiry and the item is unambiguous: one part number identifies one exact product variant, including options that are not visible in the description.

About Euchner Safety Switches and Guard Locking Systems

Euchner builds the devices that prove a machine guard is closed and, where the risk assessment demands it, keep it closed until the hazard has stopped. The CES family uses transponder-coded read heads and actuators: the actuator on the door is electronically coded to the head on the frame, which defeats the wire-and-magnet tricks that plain magnetic switches allow. MGB is the modular guard-locking system, a door handle unit that combines interlock, guard locking, escape release and optional operator controls in one housing. The TP and STA ranges are electromechanical safety switches with guard locking driven by a separate actuator tongue, and NZ and NP series position switches cover simple interlocks. Hand-held enabling switches with three-position actuation cover setup and teach work inside a guarded area. Devices in the range are designed for use in circuits up to the higher performance levels and safety integrity levels defined by ISO 13849 and IEC 62061.

Euchner Safety Switches and Guard Locking Systems in Saudi Arabia

The demand for these parts in the Kingdom follows machine guarding rather than process control. Packaging, filling and palletising lines in Saudi food and beverage plants use coded switches on hinged and sliding guards; robot cells and press lines in general manufacturing around Riyadh and Dammam use MGB handle units at the cell entry gate; cement and mining plants use guard locking where a crusher or conveyor drive coasts for a long time after the stop command. Contractors commissioning packaged machinery for Aramco and SABIC sites are asked to show that guard interlocking matches the machine risk assessment. Control circuits are typically 24 V DC, so the switch selection is independent of the 380/400 V 60 Hz supply, but ambient heat and dust in the plant argue for sealed housings and correctly mounted actuators.

Ordering and lead time

Quote the complete type designation including the six-digit order number at the end, because the same family letters cover many configurations. The read head and the actuator are usually separate order numbers, so a door needs both. State the coding type where it applies, unique or multiple coding, since that decides whether an actuator from another door will operate the switch. For MGB units, state the handle side for a left or right hand door, whether an escape release is required, whether guard locking is by spring force or solenoid force, and which pushbuttons or selector switches sit in the module. Euchner devices are sourced to order with a lead time of about three weeks, delivered duty-paid.
