The PPH-50 is a momentary push plate switch that sends a signal to a door operator or access control device. The faceplate carries an S.P.D.T. switch, so it gives you both a normally open and a normally closed contact from the same actuation. That single-pole double-throw arrangement is what lets one plate release an electrified lock on the NC side while triggering an automatic operator on the NO side. It is a switch only; the operator, lock power supply and any timing are separate devices.

The PPH-50 is the rectangular narrow plate in the Locknetics PPH Series, which is the shape you pick when there is no wall space and the switch has to land on a jamb, a mullion or a narrow column. If you have flat wall to work with, a jumbo or round plate like the Alarm Controls JP Series jumbo push plate or the Camden CM-40 4-1/2 inch round switch gives a bigger strike target for someone pushing a cart or a chair through.

No. The PPH-50 is a straight momentary switch, so the contact changes state only while the plate is pressed. Hold time has to come from the door operator or an outboard timer. If you want the delay built into the plate itself, the Alarm Controls JP Series and PD Series are pneumatic time delay push plates, and the SDC 480 Series actuators are the other common route.

The SDC 480 Series push plate actuators are the closest peer, built from 18 gauge stainless steel like the PPH-50's stainless steel faceplate. Both are hardwired push plate switches for door automation. The PPH-50 is the rectangular narrow plate and ships with a black box, and its faceplate carries engraved text with an anodized finish.

Round actuators are a different footprint entirely. Camden's CM-40 Series is a 4-1/2 inch round all-active switch and the CM-60 Series is a 6 inch round all-active switch. The Locknetics PPH-50 is a rectangular narrow plate, so if the existing cutout or the site standard is round, the Camden rounds match that shape and the PPH-50 does not.

The Locknetics PPH-50 uses a S.P.D.T. switch behind a stainless faceplate. If the delay has to live in the plate itself, Alarm Controls builds it in: the JP Series is a pneumatic time delay jumbo push plate, and the PD Series covers pneumatic time delay PD, PN, PS and PT vandal resistant push plates. Those handle the timing mechanically at the actuator rather than at a separate relay or timer.

A push plate like the Locknetics PPH-50 needs a mounting surface at the opening. Where there is none, such as an approach across open pavement or a drive aisle, SDC's BP Series square bollard posts give you the surface: 6 inch by 6 inch, with the BPS6 surface mount at 42 inches and the BPG6 in-ground at 54 inches. The bollard carries the actuator rather than replacing it.

A vestibule with two door sets is usually the case for a dedicated part. SDC's 480V Series is a vestibule push plate actuator with dual switch activation, so one press drives both leaves in sequence. The Locknetics PPH-50 is a single S.P.D.T. switch behind a rectangular narrow plate, which suits a single opening.

The Camden CM-60 Series 6 inch round all-active switch is offered wired or with a kinetic wireless transmitter, which is the option to look at when fishing wire through a finished wall or a glass front is not practical. The Locknetics PPH-50 is a hardwired S.P.D.T. switch supplied with a black box.

A black surface box ships with the PPH-50, so you do not have to cut into the wall or fish a back box in. That matters on block, tile, glass front and existing finished walls where a flush electrical box is not realistic. If you are running the plate into an existing single gang box instead, you would not need the box version.

The plate is the actuator only. You still need the automatic operator or the electrified lock it triggers, a power supply for that device, and low voltage wire from the plate back to it. On a vestibule with an inner and outer door, SDC's 480V Series is a vestibule actuator with dual switch activation for that exact sequencing problem. Where there is no wall or jamb at all to mount to, a bollard post such as the SDC BP Series (6 x 6 inch, BPS6 surface mount 42 inch or BPG6 in-ground 54 inch) carries the switch out to the approach.

A narrow rectangular plate like the PPH-50 gives a small target and has to be located precisely for reach and approach. Where the goal is that anyone touching anywhere along the column activates the door, SDC's 480AA Series is a 36 x 6 inch Ingress-R.E.X touch panel column built for ADA compliant access control, and it is the better choice when the user population includes wheelchairs and mobility devices.

The PPH-50 is part of the Locknetics PPH Series, so it shares the series' stainless faceplate and anodized engraved appearance with the other PPH plates on your other openings. Sizes differ across the series though, and the PPH-50 is the narrow rectangular one, so if the existing plates are a wider or square format the cutouts and mounting footprint will not line up one for one.

The PPH-50 is designed for use in high traffic areas and uses tamper resistant mounting, which covers most public entries. Where the concern is deliberate abuse rather than volume, the Alarm Controls PD Series is built as vandal resistant push plates in the PD, PN, PS and PT variants. The two are aimed at different kinds of wear: traffic on one side, attack on the other.

Yes. The SDC 480AA Series is a 36 inch by 6 inch Ingress-R.E.X touch panel column for ADA compliant access control, so the active surface runs the full height of the column and does not require the user to find one plate at one mounting height. The Locknetics PPH-50 is a narrow rectangular plate with a single active face, set at whatever height you mount it.

The SDC BP Series square bollard posts are the item most often ordered by mistake alongside a push plate. They are 6 inch by 6 inch mounting posts for access control, BPS6 surface mount at 42 inches and BPG6 in-ground at 54 inches, and they hold an actuator rather than acting as one. The Locknetics PPH-50 is the switch itself, a stainless steel faceplate with a S.P.D.T. switch and a black box.

Commercial. The PPH-50 is a commercial grade access control actuator, which is why it comes with an engraved and anodized stainless faceplate rather than a painted or plastic one. Engraved text will not wear off the way silkscreen does under constant hand contact.
