Miller Edge PS20A: Wired pneumatic edge switch

PS20A: Wired pneumatic edge switch

US source scopeUpdated 2026-09-14Independent Anderson reference

Match the whole number.

Manufacturer identifier: PS20A. Keep every character when comparing it with your label or paperwork. A similar number does not establish the same component.

Values apply to the exact identifier and scope in the cited source.
Edge scopeMiller Edge pneumatic configured sensing edges up to 18 feet.
MonitoringNon-monitored pneumatic switch for motorized-door sensing edges.
Switch limitsMaximum pressure 20 PSI; maximum switching frequency 25 per second.
ElectricalNormally open and normally closed outputs;2-wire configuration; maximum contact load 5 A at 250 V AC;0.187-inch tabs.
ConstructionABS enclosure, silicone diaphragm, silver-plated contacts, screw-tab mounting and NEMA12 protection.
Dimensions2 W x4-7/8 H x2 D inches (51 x124 x51 mm); listed weight3.15 ounces.
Temperature-4 to 158 degrees F (-20 to 70 degrees C).
Selection boundaryConfirm the exact door, edge configuration and installed control requirements with the manufacturer. A non-monitored component does not replace monitoring required by the installed system.

Documented fitment & exclusions

Read the exact equipment or component, market, production and variant limits in every row. An omitted pairing has not been verified by this reference.

A component pairing applies only to the listed items and source conditions. It does not establish suitability for an installed opener or compatibility through another component.

Check a part or accessory pairing

Loading part or accessory choices…

Selected: PS20A · Read its reference. Selection identifies a record; it does not confirm fitment.

Choose the equipment or accessory brand separately from the component brand. A missing identifier is unverified. Use the model library to identify your equipment and its source documents.

An accessory pairing, including a receiver or wall console, applies only to the exact listed pair and source conditions. It does not establish suitability for your installed opener or compatibility through another device.

Choose the equipment or accessory brand to load its published identifiers.

Use the production date on the label or records, not the purchase date. Leave blank if unknown.

Use part and model numbers only. Never enter a serial number, PIN or access code. Your entry is used for this lookup and is not put in the page address, saved in browser storage or sent to analytics.
